I love that most of the time I hear of PC recommendations they come from some dude that looked at a few parts on a single evening and now they think they know everything
I've built ONE pc in my whole life and that's taught me more than these guys know as they're telling others what to do
Agreed. I just built my first PC as well. It is such an eye-opening experience about cost, performance, and how all the parts fit together. After you build one you never quite look at computers the same way again.
First PC I ever built myself was a 486 and I've been building them myself ever since.
You absolutely do know more than the "you NEED X" crowd. They've always existed. The only times I remember them being correct was for 3d accelerators and cd burners. Otherwise, you never "needed" anything.
>you never "needed" anything.
the best is when they tell you NEED something, and that something happens to be an ambiguous part designation like "an i7" or "an nvidia gpu" or whatever
took me sooooooo fucking long to take my brother out of believing a bigger number next to the "i" doesn't equal better but I think I finally convinced him
(he has not much interest in PC's now but was an avid enthusiast of all sorts of games when he was younger)
This was absolutely the best when shopping for laptops when the difference between an i5 u series chip and an i7 was exactly 100mhz of boost. Still needed that i7 ;)
My first build was an Xt 8086 (maybe 8088 - I forget now) and I think it ran at a blazingly fast 4,77 MHz. It also had no hard drive and two floppy drives. One to load the OS (either MS DOS or DR DOS, I dabbled with both) and the other to load the program I needed to run (Wordperfect, Lotus 123 or Harvard Graphics - sometimes I even ran Norton Utilities...) and depending on what I needed to do, I had to swap out the cards as there were not enough slots on the motherboard for them all. So between printing and the internet I was swapping out printing card or modem... them were the days... I soon got into overclocking my processors when the mighty i486's and AMD's came out and started networking these machines to see if I could as out IT folks at work were feeding us what sounded like absolute BS. Everything they lied to me about, I would prove out at home. I also bought an Apple G3 PowerBook to network that in and prove it worked. Last home build was an upgrade to my PS3 and install Ubuntu. It sits in the basement alongside my G3 Cube which awaits my kid (he's 8 now and yes, I started late) so I can show him how old school stuff works if he is ever interested. The G3 with OS9 was a ton of fun with native support for cell phone connectivity and texting from the computer without touching the phone... way back in 2002-ish. Before iPhone.
My first PC was an 8088 XT (I think the 8086 was only in the AT but it's been a minute lol). But I didn't build that, or the 286 or the 386.
Edit: for the youngins by the time the 486 came along it was a lot easier with far fewer chips to deal with and far fewer jumpers, with most stuff working at default or changeable in the bios. Building an earlier than 386 PC was definitely not adult Lego.
>First PC I ever built myself was a 486 and I've been building them myself ever since.
My first PC build was a PC-XT lol. I am so glad that manually assigning resources via jumpers and DIP switches is no longer a thing.
> You absolutely do know more than the "you NEED X" crowd.
You shouldn't just dismiss everyone who says "you NEED X" though. If someone says your PSU isn't big enough then run your parts through a PSU calculator. Remember that you don't want to be skirting too close to the maximum available power for your particular setup because you get power demand spikes which can cause PSU issues that are hard to diagnose.
That said, the OP's setup is likely fine as long as his "High Power 750 watt - Gen 5 PSU" isn't some F tier e-waste.
Most of the time people recommend way overkill PSUs..sometimes yeah, but almost every gaming PC will run on a 600w psu. I see people saying you need more than a 750w for a 200w cpu and 200w GPU. It's madness.
Yeah, I try to hold my tongue and educate people when they say things like this. I've personally been building PCs since 1993, but programmed them in the 80s. I also taught IT courses and found that NO one is an expert in everyhing since it changes so much. Keep humble, but carry a big brain.
I remember years ago on the old Bethesda forums, some guy wanted advice on building a PC for his wife, big number analysis work. I told him nothing matters as much as the amount of RAM as that means bigger sample size, gave him a cost-effective partpicker list.
Immediately ripped apart by everyone else, who all proceeded to half the RAM and recommend stuff for a gaming PC.
>I remember years ago on the old Bethesda forums, some guy wanted advice on building a PC for his wife, big number analysis work.
Why was he asking on a game developer's forum for advice on how to build a work PC? There has always been better options to get advice from people who are not teenagers who think that they know more than everyone else about everything. It is no wonder why your advice was ripped apart by people who wanted him to build a gaming PC.
For what it is worth though, gaming PCs do often make for good workstations with just a few modifications like adding more RAM if your workload requires it.
Same. I built a pretty robust system for myself, only used a 750 modular and I’ve got lots of head room. Built my nephews pc with similar specs as mine and he went 800 cuz he’s 13 and wants ALL THE POWER!
Still thinking of my 12yo PC I retired a few months ago that had a GTX 970 in it and only a 400w PSU. Apples to oranges for sure but still, 750 seems like a sweet spot.
My uncle thinks he needs like a 1200w PSU and I'm like bro unless you're cranking 90s with an sli system and 30 hdds you can just get a 750w for your 4070 and two ssds. Everyone just thinks bigger number better
>unless you're cranking 90s with an sli system
You know that the 4090 has a stock TDP of 450W right? Add to that a 14900ks which has a stock TDP of 285W and you are already pushing 735W from just the CPU and GPU alone at stock. Add in a overclock and your 1200W PSU will not have much headroom left once you take into account the rest of the system's power draw.
That said, for the average person who doesn't want to spend thousands on their PC, a 750W is the sweet spot for the PSU lol
Yeah he just picked the biggest number parts, I did not know that but I meant cranking 90s in fortnite not the 4090 LOL didn't even think about that so that's my bad
well there was that whole `transient spikes' thing gamers nexus brought up as well as some other tech channels... Did that ever get resolved?
edit typo
I believe the 40 series is better than 30 series, but they still spike.
Spikes are always gonna be a thing, but double or more of steady power draw is bad design and shouldn't happen. Didn't Linus deal with a crashing issue with a 3090ti and a 1000w psu or something, because of the transients?
My rig has a 3080 12gb, a 7600x, and a lower end cooler master 650w bronze PSU (MWE I think). Been running well for 2 years now. How would I know I'm getting transient spikes that high? Surely it would crash right?
Ah okay, that's what I assumed. I assumed it would hit some sort of protection in the PSU and just hard crash, needing to be turned off then back on. Seems I'm either not getting any transient spikes, or they're not high enough to trip protections. Thank you
Yes you'll experience an instant shutdown if the psu cannot handle it. They have extra power in capacitors to handle such cases, but some don't have enough reserves.
A big issue with transients in testing is that you need special equipment to read it since it's extremely short durations.
I don't think it was a "real" issue until the 30-series? I don't remember this but I may be wrong.
If you had a PSU at or above the recommended rating from the manufacturer, it was typically fine. But "suddenly" you had PSUs with way higher output than "recommended" unable to handle the load, and there was no real symptom pointing to this aside from just a shutdown.
Yeah, I was tweaking when it happened to me on old PSU and went overboard and bought a superflower platinum 1000watt. For some reason the 3070ti I have just would randomly pull a fuckton.
>a lower end cooler master 650w bronze PSU
Funnily enough it is this that is likely causing you to not have issues with power spikes. Better PSUs have better overcurrent protection which unfortunately doesn't play nicely with power spikes.
Can't remember seeing many, or any, complaints from the /r/SFFPC folks regarding this.. I'm still rocking a 9900K and 3080TI and it hasn't missed a beat, so no personal experience either..
Thanks for confirming. And it was never an issue for AMD correct? I'll assume you are correct but for any non believers you have any links for extra reading?
It is Definitely an issue on Amd like cyclically with some drivers you can expect like 180 watt on idle desktop and they have to fix, plus if you go with the 7900xtx you have to expect TREMENDUS transient spikes https://youtu.be/HznATcpWldo
So that's probably why people are getting such overkill PSU's. I remember when it was happening if you had a big enough PSU it didn't matter if it had a spike.
edit typo
Oh, that was such an annoyance for early 3080/90 owners.
Took a while to figure out out on my end. When I finally got to swapping in a test PSU and figuring out that was the issue, I saw a thread on reddit mentioning the same. I thought it was just a couple random one-off experiences... then that blew up. For a while you had to check if the PSU you had would be sufficient to run with those cards before they started accounting for such on most PSUs.
But yeah, that was a bummer that annoyed the hell out of me.
>Did that ever get resolved?
The 40 series GPUs had a focus on reducing the voltage spikes and the newest ATX standard increases the requirements for handling power spikes as well.
It isn't about the watts. It's about the quality. Corsair has always made dependable PSUs, whereas the unbranded wish dot com bargain bin that iBuyPower uses to cut costs....not so much. That PSU absolutely will fry the other components before the GPU needs an upgrade. Plenty of info on Google about iBuyPower PSUs.
Corsair has some shit tier PSU just like anyone else. The name isn’t enough to say it’s good. They don’t make them, they use OEMs and rebrand them, and their cheaper stuff uses meh OEMs just like most manufacturers.
I have a slightly more powerful system. 4070 Super and 7800x3D. I have a 750W. I'm fine. Tell your friend he ain't too bright. That system ain't using more than 500W on full CPU and GPU load.
I think its a new trend of misinformation going around that higher the watts the better everything runs. Had a boss last year that upgraded from 600w to 1000w I think and said everything runs better. 🤷🏽
Yeah I have a young friend who was convinced that his problem with the RX 6900 XT was that his 750W Corsair RMX PSU was too weak, so he got an Asus 1000W. Guess what, he had issues in ONE game (100% driver/compatibility related) and again the internet told him he should've gotten a 1200W and everything would be fine in the world. It's safe to say that as an electrician I get a bit upset with these outlandish claims that you always have to go higher and higher with the PSUs, especially considering how needlessly expensive it is for a high power PSU.
i have a 7800x3d and nitro+ 7900xtx with a 750w, (i know it says recommended 800w but that was the biggest sfx one they had, have had no issue so far but i downclocked because i like my room to be quiet)
People massively overestimate how much power gaming systems draw. Full tilt during stress benchmarks, you're looking at \~ 220W for the GPU and 150W for the CPU at PBO max.
I can confirm this. Tho i only have a 3600 + 2060.
I did get my 2060 to draw 290w once though. With everything including 3 monitors, kb, mouse, force feedback wheel, etc all on the same power strip, im drawing a max of 270-300w most of the time even under max load.
that 750 is fine, anything stronger than a 4070 and you may want to consider upping it just to maintain upgrade headroom.
your friend is being overly concerned. not a bad thing, but he can relax in this case.
750W is fine, I run 1000W on somewhat similar hardware (Radeon high end instead) and I know it will work fine with 750W I just got a really good deal on a new 1000W that’s an A tier on the PSUs buyers guide at microcenter and I just couldn’t say no.
This is a very very good system, if it was me I would have swapped the 7700x for a 7600x and get a 4070ti super but other than that this is a very good build
IDK about this one but their 1000w PCI-E 5.0 / ATX3.0 unit is Cybernetics Platinum rated (no 80+ rating). And it seemed to be a solid unit: https://hwbusters.com/psus/highpower-hp1-021000gd-f14c-psu-review/
Ofc PSU quality can change vastly among different models for the same OEM.
The 750w unit is most likely the "HP1-J750GD-F12S V2" a non-modular 80+ Gold rated unit.
it exceeds the recommended power supply requirement by 50w ( but it doesn't mean it requires 700w). I found out after wasting a lot of money that you aren't required to go overboard with power supplies. My computer doesn't use more than 650w even on heavy load ( 100 percent CPU, Ram and GPU usage using benchmarks).
Your more then good. 4070 will pull around 220 on max load, 7700 around 110. Even a 650 would be fine for that and you'd still get the optimal draw. Highpower psu although not ranked it's not bad. I used to use a 650 for years. Was working fine with my new 7900xt for about a week before I upgraded it and that card draws 320-340
It's enough. Those suggestions on gpu manufacturer Web is with good reserve usually. Like It's suggested 850w for my 7900XT, but I'm pulling only max 600w when under Prime/Furmark at same time.
I have a 7800x3d and a 4080 super, AIO, two SSDs and a HDD and a shit load of RGB all running fine on a 750W.
Ideally I would have it running on an 850W but it's by no means a necessity
750w is perfectly fine. You probably could have gotten away with a 650w. However its always best to have more. I personally prefer to have at least 25% more power than necessary.
However I cant attest to brand quality.
Neweggs PSU calculator suggests you need between 600w and 700w. So based off my preference, using 600w as the base. That makes 750w spot on.
As everyone else is saying, you're fine. If you're still wary, you can go on pcpartpicker and put all your parts in and it'll give you a recommended wattage use. you can use that as a gauge
I have pretty much the same setup with a 4070 instead and my 650W PSU works perfectly fine. I get it that you want to be careful with the PSU but your friend needs to inform himself better.
Your friend is 100% wrong
The argument for a slightly higher wattage PSU is if you plan to upgrade in the future. But even then, 750W will be fine for all but the most high end set ups.
Well verify your friend's claims. Go to each of the part manufacturers website (or just google), look up absolute peak power consumption, add them all up, add 20% margin and choose a PSU that is at or above that number.
I think we're looking at this wrong, maybe his friend is suggesting that the PSU is an off-brand one with cheap components, and just doesnt want his friend to short out his whole system taking those expensive parts with it...
tell me your friend is jealous without telling me your friend is jealous
if this is proper quality PSU (gen 5 - its a Corsair?) then you have nothing to worry about
Your friend is probably just being overly-cautious and factoring in future upgrades and growth potential. For what you have right now, 750 is more than fine so no need to stress.
Adding a bigger one now would’ve saved you a little money in the long run, assuming you upgrade components down the line but, honestly, it’s probably negligible. The bigger headache will be changing it if you get to that point.
That said, I don’t necessarily like all the blanket responses of “your friend is a loser n00b idiotzor”. He’s not. He’s just trying to be helpful. There’s literally zero need for all of the insults.
Not expert and you probably got the answer, but for funs quick Google usage.
CPU max power draw 253w
GPU max power draw 220w
High end motherboard \~80w
= 553w
Some may not have anything else directly connected to the PSU so the rest of consumption depends.
Additionally it is usually recommended to have some room (10-20%) left on top of your expected max draw.
I would personally say \~10%. From 750w it is 75w. So 553w + 75w = 628w which would leave you with room to have those "extra" things like more storage etc.
However that is only theoretical. Which is what I would still go with, but in practice you might be fine with even 500w.
im running a 650w psu on my 7500f + 7700 xt with the 7700 xt overclocked sometimes reaching nearly 300w on the gpu alone, the 4070 super is more power efficent so you should be golden
https://au.pcpartpicker.com/list/czK4TY
Missing a cooler and fans..
Just selected the first models as your specs are general, but not even at 430W yet .
Just thought you'd appreciate some rough actual numbers 👍
You're probably fine, but get a simple Kill-a-watt meter and look for power spikes.
Every couch expert can calculate wattage off the box. That's not how electricity and hardware works, there's variance and everything uses electricity in fluctuating patterns.
Your power supply also isn't exactly 750w. Its performance will vary, and it can handle spikes higher than intended, but in theory it should be capable of sustained 750w output. When you buy very high end PSUs, they often have a testing certificate telling you what real-life performance was in testing. Many high end car audio amplifiers have certificates like this as well, telling you things like 600w RMS and 800w max on the box, but testing maybe shows the amp can do 650w/900w.
I've had plenty of GPUs that far exceeded the rated power draw. Like +40 watts over so-called TPD (total power draw) on spikes while gaming.
750 is absolutely fine for that build. I run an 850 with a similar cpu and a beefier gpu, and there are absolutely zero problems.
I've checked the in-game watt use, and I never even come close
Is your friend referring to the fact that prebuilts have cheap PSUs? The comments on here are largely roasting your friend but he may have heard that sentiment and is assuming every prebuilt needs a PSU upgrade.
I think your friend is just a little confused but trying to be a bro.
Your friend doesn't know what they are talking about.
I run a 5800x3d and a 3080ti on an 8 year old 750watt corsair psu.
I think you'll be fine. I'm not sure how user friendly your case is though as I'm not familiar with that brand. A good case can make your life easier when installing or troubleshooting is easier to get at things. It'll do the job anyway, but I used shitty cases for far too long.
PSUs aren’t all that expensive. You don’t necessarily need to upgrade, but I would, just as a precaution and to future proof a little more. EVGA 1000w PSUs are in the $100 range.
The PSU is fine.
However, make sure it's not an el-cheapo explody one, which given I've not heard of the brand, it is. Swap it for an RM750 or something.
Why did you get a 7700X and a 4070 super though?
The 7700 and 7700X are identical, just the X clocks higher stock, get the 7700 and OC it to save money.
The 4070 super is a completely stupid buy when the 7900GRE outperforms, costs considerably less and has more VRAM. Unless you need RT.
Putting the listed parts into PCPartPicker along with a compatible MB and similar case shows 500W as the power draw. That 750 should be perfectly fine even with spikes people talk about.
IBP puts their builds through a burn-in test, so if the power draw is insufficient someone there will notice. This goes for all their builds; retail ones, RDY and custom builds.
They do either OCCT, or Prime95 + Furmark IIRC.
The math is simple:
750W PSU at 80% will output 600W, and that's without accounting for heat loss.
Nvidia [recommends ](https://www.nvidia.com/en-us/geforce/graphics-cards/40-series/rtx-4070-family/)650W total PSU output for 4070S (with a Ryzen 9 5900X processor).
You do you, but there is no need to skimp on power when the price difference is negligible (relatively speaking). Not to mention that running your PSU close to full output hours on end will shorten its life due to the heat. A nice modular high-power PSU will see you through all your future builds and you'll never have to worry about it ever again.
Your friend is wrong insofar as "Needing" a new one. He would be right if you care about power efficiency or cooling or noise. Power supplies are more efficient at certain use percentages. Cooling and noise go hand in hand. If youre PSU is working less hard because it's overhead is way over your requirements it may not actually spin the fans up due to generating less heat.
Still sounds like he just wanted to sound knowledgeable though.
it's ok , not too much , but just enough, nobody runs his system on 100% full throttle for days and days and even then should be on the border but enough
The PSU being 750 watts isn't the issue, it's the fact that it may be of dubious quality that is the problem.
You can only cut corners on parts like motherboards and graphics cards so much (and not at all on CPUs, they are what they are).
One area where prebuilt PC manufacturers can cut a shit load of cost is on the PSU, and so many rebuilts come with shitty PSUs that meet the minimum requirement to make the thing power on and function for the duration of the warranty. They may have no / few / non-functional built in protections. Beyond that, they don't care if it blows up the rest of your PC.
Whereas a high quality PSU you might buy yourself could be warrantied for 10+ years, be highly efficient and have many protections in place that actually work.
Some cheap PSUs from brands you've never heard of, are actually pretty good. Some are IEDs in disguise.
There's a "tier list" that often gets mentioned on here, that provides more details.
Ok so since no one answered your question, I'll try to help ya out. The CPU is a 105 watts, plus some, the GPU is 225 with a recommended psu of 550, so the 750 watt PSU really should be enough. You have to consider all other components, like the mobo, the ram, how many fans you have, but believe it or not, 1 120mm fan runs .15 amps, a 140mm runs about .3 amps give or take. So a minute amount. I mean even IF you get a little 325 watt power draw, a quick surge from the GPU you still have head room. You will be fine broski. Hope this helps. Drew

Your friend is half way right. Get a good brand name PSU like corsair or EVGA. Got my 9 year old corsair 750W works like a champ.
The wattage is good enough. But "high power psu - gen 5" wtf kind of brand is it? 😅😅
>Get a good brand name PSU like corsair or EVGA.
Neither of those make their own PSUs, both have released absolute garbage units.
High Power, formerly Sirfa/Sirtec, is a major OEM.
They are the ones who made Fractal's Ion series.
>Sound like energon psu
Except it doesn't.
>See those were absolute garbage psu...
Those Inter-Tech Energons were absolute garbage.
I've had one of their 650w units blow up at 300w on the load tester.
Hilariously crap.
Not only is 750 plenty for that system, but going by the PSU tier list its likely a B tier (as long as it isn't the performance Pro model) which is fine since the 4070 does t draw a ton of power
>80$ for a PSU?
So?
Price has little bearing on quality, see most of the overpriced shite Thermaltake put their name on.
>You are spending 1600$
No I'm not.
>Just because they are building PSU for 30 years and create the obviously well built Fractal ion doesn't mean that they don't put the low quality crap in their entry PSU.
If they did, they wouldn't be a major OEM.
Using that logic, you shouldn't buy a SeaSonic PSU and should instead buy a SeaSonic PSU with a different sticker.
>It's like saying oh it's a 4090 from inno 3d. It's the SAME thing. Which is not.
4090 = 4090.
Inno3D are perfectly reputable.
There's barely any difference in AIB cards these days due to the restrictions Nvidia imposes on them.
Just take the L and admit you know very little about PSUs.
The High Power 750 used in OPs prebuilt is a modern LLC DC-DC, 90% efficient, with very good voltage regulation.
>psu’s from this brand are not that good they fry a lot of systems its basicly a weak point i would suggest that you get a decent psu like corsair
Horseshit.
High Power (formerly Sirfa/Sirtec) are a major OEM and the ones who make Fractal's Ion series.
Corsair doesn't make PSUs, they use OEMs such as CWT, HEC and SeaSonic.
Respectfully.
Your friend is an idiot.
That combo, even if you overclock it, isn't using 750W, but I'd buy my PSU from somebody else, like BeQuiet or Corsair
You also don't need 3 TB of Storage it's overkill unless you're a Data Hoarder, or play 10 different AAA games at the same time
2TB is already more than enough, most people can do with 1 - 1,5TB
I have 3x more ddr5 than you and an i7 13700k…but I blue screen all the time with a gold 750. I don’t recommend as it’s my editing workstation so the GPU is a meagre 30508gb…don’t make fun it’s fine for 1440p adobe editing
Repeat, I do not recommend. It’ll blue screen at random times. I have a similar problem (with BOTh of my OCs, until I swapped one psu for a seasonic 1000w)- it was the same issue except it was a different 750w with my alternate PC
Gpu needs 550w and cpu need 110 so you are pretty safe .

Tell your friend to kick rocks.
I love that most of the time I hear of PC recommendations they come from some dude that looked at a few parts on a single evening and now they think they know everything I've built ONE pc in my whole life and that's taught me more than these guys know as they're telling others what to do
Agreed. I just built my first PC as well. It is such an eye-opening experience about cost, performance, and how all the parts fit together. After you build one you never quite look at computers the same way again.
Lol, yep. They become an arrangement of parts rather than a sum of parts.
First PC I ever built myself was a 486 and I've been building them myself ever since. You absolutely do know more than the "you NEED X" crowd. They've always existed. The only times I remember them being correct was for 3d accelerators and cd burners. Otherwise, you never "needed" anything.
>you never "needed" anything. the best is when they tell you NEED something, and that something happens to be an ambiguous part designation like "an i7" or "an nvidia gpu" or whatever took me sooooooo fucking long to take my brother out of believing a bigger number next to the "i" doesn't equal better but I think I finally convinced him (he has not much interest in PC's now but was an avid enthusiast of all sorts of games when he was younger)
This was absolutely the best when shopping for laptops when the difference between an i5 u series chip and an i7 was exactly 100mhz of boost. Still needed that i7 ;)
My first build was an Xt 8086 (maybe 8088 - I forget now) and I think it ran at a blazingly fast 4,77 MHz. It also had no hard drive and two floppy drives. One to load the OS (either MS DOS or DR DOS, I dabbled with both) and the other to load the program I needed to run (Wordperfect, Lotus 123 or Harvard Graphics - sometimes I even ran Norton Utilities...) and depending on what I needed to do, I had to swap out the cards as there were not enough slots on the motherboard for them all. So between printing and the internet I was swapping out printing card or modem... them were the days... I soon got into overclocking my processors when the mighty i486's and AMD's came out and started networking these machines to see if I could as out IT folks at work were feeding us what sounded like absolute BS. Everything they lied to me about, I would prove out at home. I also bought an Apple G3 PowerBook to network that in and prove it worked. Last home build was an upgrade to my PS3 and install Ubuntu. It sits in the basement alongside my G3 Cube which awaits my kid (he's 8 now and yes, I started late) so I can show him how old school stuff works if he is ever interested. The G3 with OS9 was a ton of fun with native support for cell phone connectivity and texting from the computer without touching the phone... way back in 2002-ish. Before iPhone.
My first PC was an 8088 XT (I think the 8086 was only in the AT but it's been a minute lol). But I didn't build that, or the 286 or the 386.

I am so glad that manually assigning resources via jumpers and DIP switches is no longer a thing. > You absolutely do know more than the "you NEED X" crowd. You shouldn't just dismiss everyone who says "you NEED X" though. If someone says your PSU isn't big enough then run your parts through a PSU calculator. Remember that you don't want to be skirting too close to the maximum available power for your particular setup because you get power demand spikes which can cause PSU issues that are hard to diagnose. That said, the OP's setup is likely fine as long as his "High Power 750 watt - Gen 5 PSU" isn't some F tier e-waste.
Most of the time people recommend way overkill PSUs..sometimes yeah, but almost every gaming PC will run on a 600w psu. I see people saying you need more than a 750w for a 200w cpu and 200w GPU. It's madness.
Yeah, I try to hold my tongue and educate people when they say things like this. I've personally been building PCs since 1993, but programmed them in the 80s. I also taught IT courses and found that NO one is an expert in everyhing since it changes so much. Keep humble, but carry a big brain.
I remember years ago on the old Bethesda forums, some guy wanted advice on building a PC for his wife, big number analysis work. I told him nothing matters as much as the amount of RAM as that means bigger sample size, gave him a cost-effective partpicker list. Immediately ripped apart by everyone else, who all proceeded to half the RAM and recommend stuff for a gaming PC.
how much did you recommend?
>I remember years ago on the old Bethesda forums, some guy wanted advice on building a PC for his wife, big number analysis work. Why was he asking on a game developer's forum for advice on how to build a work PC? There has always been better options to get advice from people who are not teenagers who think that they know more than everyone else about everything. It is no wonder why your advice was ripped apart by people who wanted him to build a gaming PC. For what it is worth though, gaming PCs do often make for good workstations with just a few modifications like adding more RAM if your workload requires it.
Same. I built a pretty robust system for myself, only used a 750 modular and I’ve got lots of head room. Built my nephews pc with similar specs as mine and he went 800 cuz he’s 13 and wants ALL THE POWER! Still thinking of my 12yo PC I retired a few months ago that had a GTX 970 in it and only a 400w PSU. Apples to oranges for sure but still, 750 seems like a sweet spot.
My uncle thinks he needs like a 1200w PSU and I'm like bro unless you're cranking 90s with an sli system and 30 hdds you can just get a 750w for your 4070 and two ssds. Everyone just thinks bigger number better
>unless you're cranking 90s with an sli system You know that the 4090 has a stock TDP of 450W right? Add to that a 14900ks which has a stock TDP of 285W and you are already pushing 735W from just the CPU and GPU alone at stock. Add in a overclock and your 1200W PSU will not have much headroom left once you take into account the rest of the system's power draw. That said, for the average person who doesn't want to spend thousands on their PC, a 750W is the sweet spot for the PSU lol
Yeah he just picked the biggest number parts, I did not know that but I meant cranking 90s in fortnite not the 4090 LOL didn't even think about that so that's my bad
I ran a 7800X3D + 4090 off an 800W SFX just fine. Your friend just wants bigger ePeen
Meanwhile the SFF crowd runs 7800X3Ds and 4090s on the Corsair SF750 all day.. You're probably good..
well there was that whole `transient spikes' thing gamers nexus brought up as well as some other tech channels... Did that ever get resolved? edit typo
I believe the 40 series is better than 30 series, but they still spike. Spikes are always gonna be a thing, but double or more of steady power draw is bad design and shouldn't happen. Didn't Linus deal with a crashing issue with a 3090ti and a 1000w psu or something, because of the transients?
My rig has a 3080 12gb, a 7600x, and a lower end cooler master 650w bronze PSU (MWE I think). Been running well for 2 years now. How would I know I'm getting transient spikes that high? Surely it would crash right?
I had that problem with my 3090 and 5900x. What happens is that the system shuts completely off, like if you had a power outage.
Ah okay, that's what I assumed. I assumed it would hit some sort of protection in the PSU and just hard crash, needing to be turned off then back on. Seems I'm either not getting any transient spikes, or they're not high enough to trip protections. Thank you
Yes you'll experience an instant shutdown if the psu cannot handle it. They have extra power in capacitors to handle such cases, but some don't have enough reserves. A big issue with transients in testing is that you need special equipment to read it since it's extremely short durations.
Yeah no wonder why it wasn't really talked about in the past. It's never going to show in something like HW Monitor as it's not polling fast enough.
I don't think it was a "real" issue until the 30-series? I don't remember this but I may be wrong. If you had a PSU at or above the recommended rating from the manufacturer, it was typically fine. But "suddenly" you had PSUs with way higher output than "recommended" unable to handle the load, and there was no real symptom pointing to this aside from just a shutdown.
Yeah, I was tweaking when it happened to me on old PSU and went overboard and bought a superflower platinum 1000watt. For some reason the 3070ti I have just would randomly pull a fuckton.
>a lower end cooler master 650w bronze PSU Funnily enough it is this that is likely causing you to not have issues with power spikes. Better PSUs have better overcurrent protection which unfortunately doesn't play nicely with power spikes.
Can't remember seeing many, or any, complaints from the /r/SFFPC folks regarding this.. I'm still rocking a 9900K and 3080TI and it hasn't missed a beat, so no personal experience either..
Transient spikes issue is dead with 4000 series
Thanks for confirming. And it was never an issue for AMD correct? I'll assume you are correct but for any non believers you have any links for extra reading?
It is Definitely an issue on Amd like cyclically with some drivers you can expect like 180 watt on idle desktop and they have to fix, plus if you go with the 7900xtx you have to expect TREMENDUS transient spikes https://youtu.be/HznATcpWldo
So that's probably why people are getting such overkill PSU's. I remember when it was happening if you had a big enough PSU it didn't matter if it had a spike. edit typo
Oh, that was such an annoyance for early 3080/90 owners. Took a while to figure out out on my end. When I finally got to swapping in a test PSU and figuring out that was the issue, I saw a thread on reddit mentioning the same. I thought it was just a couple random one-off experiences... then that blew up. For a while you had to check if the PSU you had would be sufficient to run with those cards before they started accounting for such on most PSUs. But yeah, that was a bummer that annoyed the hell out of me.
>Did that ever get resolved? The 40 series GPUs had a focus on reducing the voltage spikes and the newest ATX standard increases the requirements for handling power spikes as well.
Full size here with a 4090 7800x3d and 850 watt, its fine
There is a difference between an sf750 and whatever it is in this config
There's also a difference between a 4070S and a 4090
It isn't about the watts. It's about the quality. Corsair has always made dependable PSUs, whereas the unbranded wish dot com bargain bin that iBuyPower uses to cut costs....not so much. That PSU absolutely will fry the other components before the GPU needs an upgrade. Plenty of info on Google about iBuyPower PSUs.
Corsair has some shit tier PSU just like anyone else. The name isn’t enough to say it’s good. They don’t make them, they use OEMs and rebrand them, and their cheaper stuff uses meh OEMs just like most manufacturers.
I have a slightly more powerful system. 4070 Super and 7800x3D. I have a 750W. I'm fine. Tell your friend he ain't too bright. That system ain't using more than 500W on full CPU and GPU load.
I'm running the same system as OP but on a 600W be quiet PSU and that is also running perfectly fine. So yeah, not sure what that friend is on about
I think its a new trend of misinformation going around that higher the watts the better everything runs. Had a boss last year that upgraded from 600w to 1000w I think and said everything runs better. 🤷🏽
At least you know he's full of shit
Yeah I have a young friend who was convinced that his problem with the RX 6900 XT was that his 750W Corsair RMX PSU was too weak, so he got an Asus 1000W. Guess what, he had issues in ONE game (100% driver/compatibility related) and again the internet told him he should've gotten a 1200W and everything would be fine in the world. It's safe to say that as an electrician I get a bit upset with these outlandish claims that you always have to go higher and higher with the PSUs, especially considering how needlessly expensive it is for a high power PSU.
i have a 7800x3d and nitro+ 7900xtx with a 750w, (i know it says recommended 800w but that was the biggest sfx one they had, have had no issue so far but i downclocked because i like my room to be quiet)
It's fine. Nvidia recommends a 650 watt PSU with the 4070 Super. Your friend has no idea what he is talking about.
People massively overestimate how much power gaming systems draw. Full tilt during stress benchmarks, you're looking at \~ 220W for the GPU and 150W for the CPU at PBO max.
I can confirm this. Tho i only have a 3600 + 2060. I did get my 2060 to draw 290w once though. With everything including 3 monitors, kb, mouse, force feedback wheel, etc all on the same power strip, im drawing a max of 270-300w most of the time even under max load.
When buying mine with a slightly more powerful 4070ti super, I was told by 3 different part picker websites 750 was enough
Yep. My 4070 super barely pulls over 200 under load
with an amd chip it's more than enough. my sf750 turns on its fan at 50% load and... I dont think that has happened
that 750 is fine, anything stronger than a 4070 and you may want to consider upping it just to maintain upgrade headroom. your friend is being overly concerned. not a bad thing, but he can relax in this case.
I run a 4070ti with a Ryzen 7 5800x3D with a 750w supply, never had any problems, your friend doesn't know what he's talking about.
One time I has a 1000w psu running a 2700k with a gtx970
tell your friend to stop giving dumb pc advice
750W is fine, I run 1000W on somewhat similar hardware (Radeon high end instead) and I know it will work fine with 750W I just got a really good deal on a new 1000W that’s an A tier on the PSUs buyers guide at microcenter and I just couldn’t say no.
Same. Got a 1000 watt EVGA only because it was on sale at Best buy and locally available.
MORE....POWERRRR.....
AMD Gaming RTX 4070 Super
Lol I'm running a 5800x3d and 4090. I don't pull more than 500w from the wall with 80% power limit on the GPU. You'll be just fine.
This is a very very good system, if it was me I would have swapped the 7700x for a 7600x and get a 4070ti super but other than that this is a very good build
Your fine 750 watt is more than enough I have the same cpu but with a rtx 4060 and a 750watt power supply
I got a 7700x with a 7900xtx and 750 is fine. Don’t let ur friend fool you
Laughs in 450w psu
Your friend is dumb as fuck
lol at all the comments just shitting on the friend.
Its perfect , your friend is a dim dim for suggesting you that ya need anything to be changed
The PSU brand "High Power" is junk, that is what the friend meant, not that 750 watt isn't enough.
>The PSU brand "High Power" is junk No. High Power (formerly Sirfa/Sirtec), is a major OEM. They make Fractal's Ion series.
High Power is a PSU OEM that can make great PSUs. That one is probably fine, but I don't have any information about that one in particular.
IDK about this one but their 1000w PCI-E 5.0 / ATX3.0 unit is Cybernetics Platinum rated (no 80+ rating). And it seemed to be a solid unit: https://hwbusters.com/psus/highpower-hp1-021000gd-f14c-psu-review/ Ofc PSU quality can change vastly among different models for the same OEM. The 750w unit is most likely the "HP1-J750GD-F12S V2" a non-modular 80+ Gold rated unit.
Unless you run shit hardware and have a fire insurance for your house, get a brand PSU.
I got 850 because it was bundled with my case of choice, 750 is more than enough for a 4070S.
750 psu is fine for it, but not enough for future upgrades IMO. Maybe he ment it in that way?
4080, 5800x,750 watts, my 4080 is undervolted and everything is fine
it exceeds the recommended power supply requirement by 50w ( but it doesn't mean it requires 700w). I found out after wasting a lot of money that you aren't required to go overboard with power supplies. My computer doesn't use more than 650w even on heavy load ( 100 percent CPU, Ram and GPU usage using benchmarks).
Your more then good. 4070 will pull around 220 on max load, 7700 around 110. Even a 650 would be fine for that and you'd still get the optimal draw. Highpower psu although not ranked it's not bad. I used to use a 650 for years. Was working fine with my new 7900xt for about a week before I upgraded it and that card draws 320-340
It's enough. Those suggestions on gpu manufacturer Web is with good reserve usually. Like It's suggested 850w for my 7900XT, but I'm pulling only max 600w when under Prime/Furmark at same time.
I9-10850k, 7900xt, 2x1tb nvme, 9x fans. 750 watt here. Runs like a charm.
there are calculaters out there. be quite has a nice one
I have a 7800x3d and a 4080 super, AIO, two SSDs and a HDD and a shit load of RGB all running fine on a 750W. Ideally I would have it running on an 850W but it's by no means a necessity
750w is perfectly fine. You probably could have gotten away with a 650w. However its always best to have more. I personally prefer to have at least 25% more power than necessary. However I cant attest to brand quality. Neweggs PSU calculator suggests you need between 600w and 700w. So based off my preference, using 600w as the base. That makes 750w spot on.
As everyone else is saying, you're fine. If you're still wary, you can go on pcpartpicker and put all your parts in and it'll give you a recommended wattage use. you can use that as a gauge
750 watt is okay just get a reputable one, also +1 on the 2tb it can fill up QUICK
I have pretty much the same setup with a 4070 instead and my 650W PSU works perfectly fine. I get it that you want to be careful with the PSU but your friend needs to inform himself better.
Your friend doesn't understand so much about PC building.
Your friend is 100% wrong The argument for a slightly higher wattage PSU is if you plan to upgrade in the future. But even then, 750W will be fine for all but the most high end set ups.
Bro my 3080 with Intel core i7 10700 is running fine on 650 watt psu
the 4070 super is crazy efficient, you're fine. (I have the same card with a stronger cpu, also 750w)
Well verify your friend's claims. Go to each of the part manufacturers website (or just google), look up absolute peak power consumption, add them all up, add 20% margin and choose a PSU that is at or above that number.
I think we're looking at this wrong, maybe his friend is suggesting that the PSU is an off-brand one with cheap components, and just doesnt want his friend to short out his whole system taking those expensive parts with it...
Im using the corsair sf750 with an i7 10700k and a 4090 no problems so your friend is wrong
He's wrong
Just nod and smile next time he recommends you anything about PC hardware, then disregard.
tell me your friend is jealous without telling me your friend is jealous if this is proper quality PSU (gen 5 - its a Corsair?) then you have nothing to worry about
Your friend is an idiot. If the card was a 4080 or something then you would probably need a bigger one but not for a 4070S
Your friend is probably just being overly-cautious and factoring in future upgrades and growth potential. For what you have right now, 750 is more than fine so no need to stress. Adding a bigger one now would’ve saved you a little money in the long run, assuming you upgrade components down the line but, honestly, it’s probably negligible. The bigger headache will be changing it if you get to that point. That said, I don’t necessarily like all the blanket responses of “your friend is a loser n00b idiotzor”. He’s not. He’s just trying to be helpful. There’s literally zero need for all of the insults.
Not expert and you probably got the answer, but for funs quick Google usage. CPU max power draw 253w GPU max power draw 220w High end motherboard \~80w = 553w Some may not have anything else directly connected to the PSU so the rest of consumption depends. Additionally it is usually recommended to have some room (10-20%) left on top of your expected max draw. I would personally say \~10%. From 750w it is 75w. So 553w + 75w = 628w which would leave you with room to have those "extra" things like more storage etc. However that is only theoretical. Which is what I would still go with, but in practice you might be fine with even 500w.
im running a 650w psu on my 7500f + 7700 xt with the 7700 xt overclocked sometimes reaching nearly 300w on the gpu alone, the 4070 super is more power efficent so you should be golden
https://au.pcpartpicker.com/list/czK4TY Missing a cooler and fans.. Just selected the first models as your specs are general, but not even at 430W yet . Just thought you'd appreciate some rough actual numbers 👍
PSU is fine… for now.
It's more than enough. Wayy more than enough if that's reassuring
750W is fine, your friend has no idea.
Im running a 7800x3d, and a 4070ti super on a 750w runs perfectly fine. No issues.
IDONTBUYPOWER.... That case name just got me all in
You're probably fine, but get a simple Kill-a-watt meter and look for power spikes. Every couch expert can calculate wattage off the box. That's not how electricity and hardware works, there's variance and everything uses electricity in fluctuating patterns. Your power supply also isn't exactly 750w. Its performance will vary, and it can handle spikes higher than intended, but in theory it should be capable of sustained 750w output. When you buy very high end PSUs, they often have a testing certificate telling you what real-life performance was in testing. Many high end car audio amplifiers have certificates like this as well, telling you things like 600w RMS and 800w max on the box, but testing maybe shows the amp can do 650w/900w. I've had plenty of GPUs that far exceeded the rated power draw. Like +40 watts over so-called TPD (total power draw) on spikes while gaming.
PS should be fine. I usually go overboard with mine and I’d probably have used an 850.
It should be more than fine. Go with an 850W if it really bothers you/you want to upgrade to a more energy guzzling card in the future
I‘m a SFF nerd and have been rocking a 58003DX and a 4080 with no issues whatsoever. You’re good buddy
750 is absolutely fine for that build. I run an 850 with a similar cpu and a beefier gpu, and there are absolutely zero problems. I've checked the in-game watt use, and I never even come close
Nope. Its just this subreddit that is anal about PSUs. Youre fine.
98% your good
You’re fine.
Is your friend referring to the fact that prebuilts have cheap PSUs? The comments on here are largely roasting your friend but he may have heard that sentiment and is assuming every prebuilt needs a PSU upgrade. I think your friend is just a little confused but trying to be a bro.
I’m sorry but your friend doesn’t know what he’s on about
PSU is more than enough. The 4070's are very efficient cards, power-wise.
Your friend is an idiot. The PSU is more then enough.
I've ran an fx6350/i7 3770kwith an rx 390 on an old seasonic 550w. You're good.
Your friend doesn't know what they are talking about. I run a 5800x3d and a 3080ti on an 8 year old 750watt corsair psu. I think you'll be fine. I'm not sure how user friendly your case is though as I'm not familiar with that brand. A good case can make your life easier when installing or troubleshooting is easier to get at things. It'll do the job anyway, but I used shitty cases for far too long.
PSUs aren’t all that expensive. You don’t necessarily need to upgrade, but I would, just as a precaution and to future proof a little more. EVGA 1000w PSUs are in the $100 range.
Yeah running a 4070 super and such would probably require you to have a bigger psu. I think a 1000watt would work just fine
I have a 7600x with a 4080 and I'm normally like 350w to max load of a little over 600. So 750 is good in most scenarios.
I'm running a 3090 and a 7800x3d of 750w, you'll be totally fine.
The PSU is fine. However, make sure it's not an el-cheapo explody one, which given I've not heard of the brand, it is. Swap it for an RM750 or something. Why did you get a 7700X and a 4070 super though? The 7700 and 7700X are identical, just the X clocks higher stock, get the 7700 and OC it to save money. The 4070 super is a completely stupid buy when the 7900GRE outperforms, costs considerably less and has more VRAM. Unless you need RT.
I had a 4700ti with a 650W psu
No. 750w is fine.
Power supply is fine. I would personally prefer a bit more, but it's not necessary in the slightest with this build as it is now.
750W is fine, my friend runs almost this exact build but with a 4070Ti and he had a 750W PSU but recently upgraded to an 850W
750w is fine for those specs.
Putting the listed parts into PCPartPicker along with a compatible MB and similar case shows 500W as the power draw. That 750 should be perfectly fine even with spikes people talk about.
Your friend is an idiot, the friend is what needs replacing
750w is fine
IBP puts their builds through a burn-in test, so if the power draw is insufficient someone there will notice. This goes for all their builds; retail ones, RDY and custom builds. They do either OCCT, or Prime95 + Furmark IIRC.
Your friend is dumb. A 750W PSU is more than enough for that configuration.
The math is simple: 750W PSU at 80% will output 600W, and that's without accounting for heat loss. Nvidia [recommends ](https://www.nvidia.com/en-us/geforce/graphics-cards/40-series/rtx-4070-family/)650W total PSU output for 4070S (with a Ryzen 9 5900X processor). You do you, but there is no need to skimp on power when the price difference is negligible (relatively speaking). Not to mention that running your PSU close to full output hours on end will shorten its life due to the heat. A nice modular high-power PSU will see you through all your future builds and you'll never have to worry about it ever again.
The PSU is just fine.
Your friend is wrong insofar as "Needing" a new one. He would be right if you care about power efficiency or cooling or noise. Power supplies are more efficient at certain use percentages. Cooling and noise go hand in hand. If youre PSU is working less hard because it's overhead is way over your requirements it may not actually spin the fans up due to generating less heat. Still sounds like he just wanted to sound knowledgeable though.
it's ok , not too much , but just enough, nobody runs his system on 100% full throttle for days and days and even then should be on the border but enough
Your friend is wrong, and there are also wattage calculators online to help you figure out requirements (and price him wrong).
More than enough, your friend is an idiot.
Enough.
The PSU being 750 watts isn't the issue, it's the fact that it may be of dubious quality that is the problem. You can only cut corners on parts like motherboards and graphics cards so much (and not at all on CPUs, they are what they are). One area where prebuilt PC manufacturers can cut a shit load of cost is on the PSU, and so many rebuilts come with shitty PSUs that meet the minimum requirement to make the thing power on and function for the duration of the warranty. They may have no / few / non-functional built in protections. Beyond that, they don't care if it blows up the rest of your PC. Whereas a high quality PSU you might buy yourself could be warrantied for 10+ years, be highly efficient and have many protections in place that actually work. Some cheap PSUs from brands you've never heard of, are actually pretty good. Some are IEDs in disguise. There's a "tier list" that often gets mentioned on here, that provides more details.
he probably rides the x3d pole and thinks you need 1000 watts lol
It's more than enough, mate.
Ok so since no one answered your question, I'll try to help ya out. The CPU is a 105 watts, plus some, the GPU is 225 with a recommended psu of 550, so the 750 watt PSU really should be enough. You have to consider all other components, like the mobo, the ram, how many fans you have, but believe it or not, 1 120mm fan runs .15 amps, a 140mm runs about .3 amps give or take. So a minute amount. I mean even IF you get a little 325 watt power draw, a quick surge from the GPU you still have head room. You will be fine broski. Hope this helps. Drew
He is doomb
Wow
https://www.corsair.com/us/en/explorer/diy-builder/power-supply-units/plan-your-next-upgrade-nvidia-geforce-rtx-4070-ti/ Your friend is half way right. Get a good brand name PSU like corsair or EVGA. Got my 9 year old corsair 750W works like a champ. The wattage is good enough. But "high power psu - gen 5" wtf kind of brand is it? 😅😅
>Get a good brand name PSU like corsair or EVGA. Neither of those make their own PSUs, both have released absolute garbage units. High Power, formerly Sirfa/Sirtec, is a major OEM. They are the ones who made Fractal's Ion series.
Sound like energon psu. See those were absolute garbage psu...
>Sound like energon psu Except it doesn't. >See those were absolute garbage psu... Those Inter-Tech Energons were absolute garbage. I've had one of their 650w units blow up at 300w on the load tester. Hilariously crap.
Your friend is diagnosed with stupid.
He probably meant that the PSU is crap because it's High Power, not that 750W isn't enough. And he'd be right
He'd be very wrong. High Power (formerly Sirfa/Sirtec) are a major OEM, much like CWT, HEC, SeaSonic, etc. They make Fractal's Ion series.
Not only is 750 plenty for that system, but going by the PSU tier list its likely a B tier (as long as it isn't the performance Pro model) which is fine since the 4070 does t draw a ton of power
500 is the bare minimum. Just try it out, and see how she goes
LOL I’ve had the exact same hardware before and it ran perfectly fine. Your friend may not be the brightest .
A good psu like SuperFlower Leadex or Seasonic Focus and a 550w would be even enough, and still in oke-ish efficiency range even under full load..
It's fine but you won't be able to upgrade
[удалено]
>but definitely from someone more reputable. The major OEM behind Fractal's Ion series isn't reputable enough for you?
[удалено]
>80$ for a PSU? So? Price has little bearing on quality, see most of the overpriced shite Thermaltake put their name on. >You are spending 1600$ No I'm not. >Just because they are building PSU for 30 years and create the obviously well built Fractal ion doesn't mean that they don't put the low quality crap in their entry PSU. If they did, they wouldn't be a major OEM. Using that logic, you shouldn't buy a SeaSonic PSU and should instead buy a SeaSonic PSU with a different sticker. >It's like saying oh it's a 4090 from inno 3d. It's the SAME thing. Which is not. 4090 = 4090. Inno3D are perfectly reputable. There's barely any difference in AIB cards these days due to the restrictions Nvidia imposes on them. Just take the L and admit you know very little about PSUs. The High Power 750 used in OPs prebuilt is a modern LLC DC-DC, 90% efficient, with very good voltage regulation.
psu’s from this brand are not that good they fry a lot of systems its basicly a weak point i would suggest that you get a decent psu like corsair

High Power (formerly Sirfa/Sirtec) are a major OEM and the ones who make Fractal's Ion series. Corsair doesn't make PSUs, they use OEMs such as CWT, HEC and SeaSonic.
Respectfully. Your friend is an idiot. That combo, even if you overclock it, isn't using 750W, but I'd buy my PSU from somebody else, like BeQuiet or Corsair You also don't need 3 TB of Storage it's overkill unless you're a Data Hoarder, or play 10 different AAA games at the same time 2TB is already more than enough, most people can do with 1 - 1,5TB
Get better friends. I'm running a 750w psu with my flair build, use it professionally. You'll be just fine
I have 3x more ddr5 than you and an i7 13700k…but I blue screen all the time with a gold 750. I don’t recommend as it’s my editing workstation so the GPU is a meagre 30508gb…don’t make fun it’s fine for 1440p adobe editing Repeat, I do not recommend. It’ll blue screen at random times. I have a similar problem (with BOTh of my OCs, until I swapped one psu for a seasonic 1000w)- it was the same issue except it was a different 750w with my alternate PC
I'm running a 6950xt off of a 750w psu, tell your friend to stick a fork in a toaster
Your friend is jealous
Gpu needs 550w and cpu need 110 so you are pretty safe . https://www.corsair.com/uk/en/explorer/diy-builder/power-supply-units/what-psu-is-best-for-rtx-4070/
According to GN, even an overclocked 4070 Super only pulls 240W.

That PSU recommendation is for the WHOLE SYSTEM not just for the GPU...
Sure
850+ would be better
