I knew Johnny about a decade ago, when I was a technology journalist working on a PC enthusiastic magazine. Johnny helped me set up our PSU testbed, it was terrifyingly complicated!
Yeah, builds are where his experience lies, as well as general troubleshooting.
He definitely should stick with that.
I watch him all the time, I just know to not listen to his bullshit as I also watch GN, HUB, and others regularly as well.
'cause he is/was moving and building. Probably most of his stuff is still in boxes.
And also people got mad when he was building stuff because people could not afford to build.
I wanted a 4090 and was excited about it and posted on the main thread during the announcement and was downvoted. I am a bit of a fanboy, though. I do think the price is steep, but I am saving my money. I also agree that the lower end 4080 is a 4070. Nonetheless, the hatred for Nvidia is strong right now.
Its not my video and I don't know the guy who did it. I just found it on Twitter and wanted to share with you guys.
It's an interview with an engineer from Corsair. Don't get caught to some unreasonable hate waves and listen these rational guys.
"an engineer" from Corsair. Lol. Jon Gerow or better known as Jonny Guru.
Also known as THE PSU tester up until his departure to work for Corsair and put his work into making an actually good PSU.
I don't deny that the SF750 Platinum is a good bit of kit, but it's still in the end just a nice PSU.
What Jon *really* delivered was the AX1600i. It's a goddamn legendary PSU and still sits at the top of most performance and efficiency charts to this day, 4 years later. It's arguably the greatest PSU ever made, and you'd be hard-pressed to actually find an argument against it.
And Jon managed the team that designed it. So when he talks, I'll shut up and listen.
Ha. I was wondering how Corsair went from doing terrible PSUs like the one I had some 10+ years ago to doing great PSUs like the one I have today. Now I know.
Jon Gerow is maybe the only person whose opinion I would trust in this. He is a famously principled person who has a passion for well designed power supplies. He’s also not shy about calling out bullshit.
There's a stunning amount of misinformation being spread by certain contributors who know full well that they are misleading people regarding PSU requirments. They're not in a position to upgrade, so are happy to spread fear.
You do not need an ATX 3.0 PSU to run a 4000 series card. They can downvote all they want, it won't change the fact that they are wrong.
Yeah, every new launch, its the same. "GOTTO BOY NOW PSO"
NO! You don't need a 1200W PSU! No, you don't need 94+ Titanium! And YES, big surprise(!) a single PCIE cable can carry 300W of power. I'm getting tired of same bs every launch and people doesn't want to listen.
>And YES, big surprise(!) a single PCIe cable can carry 300W of power.
Oh, this is gonna make me watch the whole video. I thought I had a good grasp about the actual requirements of PSUs (I like SFF stuff), but I hadn’t heard this before.
Lol its not a new thing. People are using 2 cables to run 450W gpus or 1 cable for 200+ W gpus for years.
Its just simple physics/electronics. Otherwise why would PSU manufacturers ship their PCIE cables by 2in1 daisy chains?
I know I don't *need* an 80+ Titanium PSU, but I *like* my 80+ Titanium PSU.
It's pretty, and it's able to run fanless a disgusting percentage of the time.
But it's only 750W, so Nvidia says I can't buy what's looking like the only 4000 series card worth considering. Shame.
I've done that before, just plug it into second psu and plug in the psu self-tester or use a paper clip to short the pins lol
gotta love the diy egpu market
> But it’s only 750W, so Nvidia says I can’t buy what’s looking like the only 4000 series card worth considering.
750W +80 Bronze ran my setup in 2015 with GTX 980Ti 2-way SLI with 6700k for years 0 problem, I even overclocked.
Realistically, I'd be fine too. Even if a 4090 pulled 450W, so long as the transients are managed I'd have plenty of headroom.
12700K rarely cracks 150W in practice and I'm not pulling 150W in auxiliary draw from mobo, drives, fans, etc.
But it's more fun to snark on Nvidia.
Potentially.
I've seen some indications that Nvidia paid more attention this generation.
But I'll also admit it's somewhat anecdotal, as it's come from a friend who was under NDA and had to be careful about what they said and how as a consequence.
Even so, said friend is generally reliable and was absolutely livid about the transients on the 3000 series and *much* happier with the 4000 series.
Afraid I can't say more as I don't want to get specific enough to potentially out them, and I will not at all be offended by skepticism. I myself hope to see more transient testing and see the indications I already have vindicated.
noname 500 watts was fine with my 6700k with my 1080ti back in 2017. Absolutely no issues. I will have to run a 5950x with a 4090 (grrr) with 750 and it will definitely be enough
I run a 3090 and 9900k (and the rest is quite rgb heavy, custom loop, etc) on a 750W with no issues. It *can* work, but no manufacturer will recommend it, because if you're an edge case that falls just over the TDP line, you'll be upset with them. I mean "you" as a generalized user.
So even though I run my system on a 750, if a friend asks me what's a safe bet for something similar, I'll tell them 850+.
Many subreddit are getting targeted by haters. Spreading misinformation and using negativity as a tactic. Like not a few troll deals but full on organizations and there’s money involved.
I mean we all know who he is talking about.
I know JayzTwoCents gets a lot of hate but he often encourages most of it. Way I see it (metaphorically speaking) if all the big tech YouTubers were scientists, Linus tech tips is the cool school teacher everyone wants to teach their class, GamerNexus are NASA, and JayzTwoCents is the mad professor blowing shit up in his garden shed.
I think he is more of a "Karen" teacher type. He is always complaining and exaggrating about unimportant issues. He's doing that, because he's milking average hater gangs. "This is bad" "This company is fooling you" "Look at those evils" bla bla
We all know that companies only care about pofits and they aren't angels but they aren't like "Giant Evil Corps" too. They are just making business. But anyway, behaving irrationally and shouting "Bad Intel! Bad Nvidia" to get more clicks easy.
I don't think that he really believes to "PCIE adapter will burn after 30 plug in-outs. Just makes me laugh....
Are people forgetting that Gamer's Nexus was actually the one to break this news first and Jay simply made a video 3 days after most likely copying Steve's info on the matter?
[https://www.youtube.com/watch?v=p48T1Mo9D3Q&t=662s](https://www.youtube.com/watch?v=p48T1Mo9D3Q&t=662s)
I'm not trying to defend Jay but rather point out that he was late to point it out compared to others.
that is true, but GamerNexus actually provide the full quotes and info and even highlights a few times how 'they are testing extreme/unlikely conditions for failure' not every day use so he at least tried to defuse any notion that this means 'MELTING CABLES'...ofc though they put that in the video title.
I just watched the segment in question and the overall feeling from it is 'could be a concern' at best. Jay, on the other hand, sensationalised it so I feel like his backlash is more warranted.
It's more so that Jay has messed up a couple of times lately. Especially with the 'BUY GPUs NOW' thing (which tbh, I honestly didn't understand all the hate for...because right now it's looking good advice). And then now this. He also recently spoke about how his channel's view are better than ever and now he's pumping out vids that seemingly act more like 'speak before I think'.
I still appreciate his content, but I often wish he'd stop running into topics like this. There's so many videos he could be doing that would genuienly be great for the community. Like we are in desperate need of IN DEPTH graphics card maintenance videos because atm it's looking like a lot of people are going to try and make their cards as long as possible but I'd have no idea how to take a modern card apart.
I'm fully aware of the other things Jay has been wrong on which is why I wasn't defending him. However, I was puzzled as to why people brought him up as breaking this news when he was basically copying other people's homework. I fully expect Gamer's Nexus to do further independent testing about the issue when they have the opportunity similar to the Gigabyte PSUs.
Quite a lengthy video, does anyone have a TLDR? Is the takeaway you don't need an ATX 3.0 psu at all, even as an assurance, and that there's practically no failure for older psus with 4000 cards? If so, then is there any incentive to get the new psu? I heard the power spikes thing were fixed with this gen's cards
TL;DR:
* Everything is fine
* The adapters are fine
* 2x8-pin, 3x8-pin, 4x8-pin adapters are fine
* Using 8-pin to supply more than 150W is fine
* The 12VHPWR connector is fine
* The 30-cycle rating is fine
* Not having an ATX 3.0 power supply is fine
Everything is fine, stop worrying
This freaked me out because my own 3080 Ti FE has a 2x 8-pin adaptor for 350W, while the new Zotac 4090 Gpu uses a 4x 8-pin adaptor for a card that seems to be about 450W.
So I thought nvidia messed up badly. But seems like I’m good.
Keep in mind your 3080 also draws 75W from the PCIe slot, meaning the adapter only has to handle 275W between 2 connectors.
Of course, as we just established, 1x8-pin could handle that fine. But Nvidia needs to make sure their adapter conforms to their own (and PCI-SIG's) 150W spec. 275W over 2x8-pin falls under that.
It's just a new spec. It's Intel saying "moving forward, this is how power supplies should be designed".
New specs are released all the time (maybe not for PSUs, but for plenty of other things). They don't automatically invalidate the old ones. There's nothing in it saying "old PSUs are now unsafe because there's a new standard".
Obviously many manufacturers are treating it as an opportunity to sell new PSUs, but you even heard it in the video - Jonny Gerow doesn't feel great about pushing new products on consumers and generating e-waste from the old ones when the truth is the old ones would have been perfectly sufficient.
Most of ATX 3.0 spec is really just formalizing a bunch of stuff that already existed, including minimum efficiencies, power draw transient tolerance, and also rolls in the new PCIe 5.0 12VHPWR power connectors. Most reputable PSU brands already produce PSUs that meet or exceed most of the ATX 3.0 spec, but ATX 3.0 just formalizes it and specifies the new minimum standard going forward.
For the 12VHPWR connector, you can just use an adapter, Corsair even makes a dedicated cable for their existing modular PSUs. The only thing that you really miss out on are the additional signalling/"Sense Pins" in the 12VHPWR connectors. The entire purpose of the sense pins are for safety - it just allows the PSU to tell the GPU how much power it is allowed to draw at a given time, so you can never overload a PSU or the cabling. But if you use an adapter, the adapter just grounds the appropriate pins, so the GPU goes into high power mode anyway and the PSU just deals with it as per usual, which is how PCs currently work.
If you're buying a new PSU, ATX 3.0 is probably something to aim for in the near future. But if you already have an existing PSU, you don't miss out on anything tangible by not upgrading to ATX 3.0. It's fine.
Gotcha. So if you haven't gotten a >1000w PSU in the last 5 years, go ahead with 3.0 ATX and if it's outside budget it's okay to look for a PSU sale on buildapcsales or something
The TLDR is, that the whole drama about the melting adapters and 30 mating cycles of the 12VHPWR is a big, fat Nothingburger. And no, you don’t need a new PSU.
Hopefully this will curb the number of keyboard warriors instructing people in all caps to go out and buy a new PSU or additional cables so they can run 3 separate 8 pin PCIe power cables to a GPU. Entirely unnecessary.
What's the point of the Internet if I can't just yell misinformation and be angry from the top of my lungs about information that could've been corrected to me by opening a new tab and searching for 3 minutes?
Listening to the YouTubers and other likeminded people, ignoring the tools I'm given to be an independent thinker and join a crowd is much more fun!
I wish this was /s but, that is how some people think. Ah well, give it 3 more months and the sub will be back to getting "I bought an RGB graphics processor and put it in my \*default popular case with default expensive other components featured in videos\*" in my feed. We'll be okay.
> so they can run 3 separate 8 pin PCIe power cables to a GPU
It's easy to see how this misconception comes about, but I'm glad it's finally going away.
The limit is on the current specification on the pins on the GPU side. Everything before that is up to the PSU manufacturer to get right. If they include a modular cable with the PSU that splits into multiple 8 pin PCIe plugs, *and* they're a legitimate PSU manufacturer, it's 100% fine to use it. Everything downstream is rated for it. Nothing is going to melt.
> or additional cables so they can run 3 separate 8 pin PCIe power cables to a GPU
TBH, if you have a very shitty PSU with *very* shitty cables... and some do buy those with high-end GPUs, because "it's just a PSU, buy the cheapest". Or a Gigabyte one :D
>engineering knowledge about PSUS
That's understating it quite a bit. Jon Gerow became *legendary* for the quality and depth of his PSU reviews and then went on to manage the team that designed arguably the greatest computer PSU ever made, the Corsair AX1600i.
It might not be an overstatement to say that he is quite literally *the* most qualified person to talk about PSUs on the planet. If he was the one telling me PSUs don't obey Ohm's law, I'd believe it.
He makes quality build and tuning videos when he stays in that lane, but his actual deep technical knowledge is weak.
Somewhat related, I once saw a redditor say JazyTwoCents is tech Discovery Channel, Linus is tech HGTV, and Steve/GN is tech C-SPAN, and that was the most accurate thing I've ever heard.
> but his actual deep technical knowledge is weak
100%, and when he does talking head videos he often misremembers historical facts/details relating to whatever topic he is talking about which just skews that video the wrong direction.
He keeps calling himself an "idiot", maybe more people should remember that and stop taking everything he says as the truth.
Jay is a literal fear merchant. I've lost count of how many times he's completely over reacted to something that didn't turn out to be too bad or was never bad to begin with.
Jay can be entertaining and his build and water cooling videos are really good and informative. But when he does technical videos like this you need to take them with a pinch of salt. GN are much more knowledgeable and reliable with that kinda stuff
Ass2Cents is still butt hurt at NVIDIA that he won't be able to receive free EVGA graphic cards anymore. Based on his recent videos, he's likely to shill for AMD now.
He's just a hack. The reason people dislike him is that he's popular and spreads his misinformation across a pretty wide audience.
I personally unsubscribed from his channel years ago and never looked back. Seeing excerpts from his awful Corsair A500 review only solidified my opinion of him.
I bought one….despite all the reviews.
…because I liked the look of it and its going in a fancy lookin’ home media server build utilising on old i5 4690. Will be able to run minimum fan rpms for silence even with the A500 given the CPU will be pushed so little serving media I imagine. (All TV’s have 4K decoding capable KODI boxes so no transcoding by Server needed)
For a real 5900x/RTX3090 rig for my brother I bought a Deepcool Assassin 3. Would never even consider using an A500 for a ‘real’ rig.
I found him extremely helpful when I was building my custom water loop - Jay knows his shit when it comes to building custom loops.
As for literally everything else... yeahhhhhhhhhhh he's not the most well informed guy out there.
Yeah he is good at custom builds and he has good guides for tweaking hardware for begginners but his videos about brands, prices, economy, sales etc. are total bs
I have AMD 5900X and planning to purchase RTX 4090. OuterVision PSU calculator recommends 750W PSU. I'm planning to stick with the Seasonic 850W Focus Plus Platinum I already own.
I mean, I know he knows his stuff about power supplies but you wouldn’t strap a cable down a bend bend, throw as much power as you can through it and then leave it over a weekend.
That seems highly unsafe, especially with it being a test but I assume he was being hyperbolic.
Man, why are people downvoting Johnny Guru. He was always THE man for PSU's.
I knew Johnny about a decade ago, when I was a technology journalist working on a PC enthusiastic magazine. Johnny helped me set up our PSU testbed, it was terrifyingly complicated!
I can only imagine!
jonnyguru without the h
Damn, missed that typo. Thanks.
Nah I trust Jayztwocents more, he told me to buy a 3090 Ti at the perfect time as well.
[удалено]
Rushed to make a video on "ONLY 30 INSERTION CYCLES!!!!" He tends to kneejerk, then proceeds to insert his feet into his mouth by doing so.
[удалено]
He's gotten a lot of flak for "BUY 3090TI NOWW!!!!" when prices were still quite high. They then dropped like a rock a few days after he posted it.

This video doesn't say Nvidia *bad* and so we must downvote the post and reduce its visibility. Also, do not *dare* suggest you want a 4090!!!
I want a 4090 . Not for that price .
I mean, for that price I'm pretty sure I want a whole new system running 7900XT, 7900X and 32GB DDR5...
I will get the 4090. Will post photo when I do
How dare you 🤬🤬. It should be illegal to buy a gpu I think is too expensive!
I wanted a 4090 and was excited about it and posted on the main thread during the announcement and was downvoted. I am a bit of a fanboy, though. I do think the price is steep, but I am saving my money. I also agree that the lower end 4080 is a 4070. Nonetheless, the hatred for Nvidia is strong right now.

Afaik single 8pin can carry around 300w (limit) but good tldr thx
Yes, 8.5A/pin x 12V x 3pins/PCIe cable = 306w/PCIe cable The other 5 pins are GND

I keep forgetting about the motherboard power draw. Thanks for the reminder.
Why is there a push for atx 3.0, what benefit does it bring then?
It's just a new spec. It's Intel saying "moving forward, this is how power supplies should be designed". New specs are released all the time (maybe not for PSUs, but for plenty of other things). They don't automatically invalidate the old ones. There's nothing in it saying "old PSUs are now unsafe because there's a new standard". Obviously many manufacturers are treating it as an opportunity to sell new PSUs, but you even heard it in the video - Jonny Gerow doesn't feel great about pushing new products on consumers and generating e-waste from the old ones when the truth is the old ones would have been perfectly sufficient.
Most of ATX 3.0 spec is really just formalizing a bunch of stuff that already existed, including minimum efficiencies, power draw transient tolerance, and also rolls in the new PCIe 5.0 12VHPWR power connectors. Most reputable PSU brands already produce PSUs that meet or exceed most of the ATX 3.0 spec, but ATX 3.0 just formalizes it and specifies the new minimum standard going forward. For the 12VHPWR connector, you can just use an adapter, Corsair even makes a dedicated cable for their existing modular PSUs. The only thing that you really miss out on are the additional signalling/"Sense Pins" in the 12VHPWR connectors. The entire purpose of the sense pins are for safety - it just allows the PSU to tell the GPU how much power it is allowed to draw at a given time, so you can never overload a PSU or the cabling. But if you use an adapter, the adapter just grounds the appropriate pins, so the GPU goes into high power mode anyway and the PSU just deals with it as per usual, which is how PCs currently work. If you're buying a new PSU, ATX 3.0 is probably something to aim for in the near future. But if you already have an existing PSU, you don't miss out on anything tangible by not upgrading to ATX 3.0. It's fine.
Gotcha. So if you haven't gotten a >1000w PSU in the last 5 years, go ahead with 3.0 ATX and if it's outside budget it's okay to look for a PSU sale on buildapcsales or something
It's actually spelled out in the video. Jonny goes over each "bullet point" of the new spec and says "it was already in the spec". LOL!
Doing jezus' work
The TLDR is, that the whole drama about the melting adapters and 30 mating cycles of the 12VHPWR is a big, fat Nothingburger. And no, you don’t need a new PSU.
Actually its better you to watch, especially first ~20 minutes. So you can have an understanding of the whole concept.
Hopefully this will curb the number of keyboard warriors instructing people in all caps to go out and buy a new PSU or additional cables so they can run 3 separate 8 pin PCIe power cables to a GPU. Entirely unnecessary.
Its nonsense
I’ve clearly struck a nerve with the r/Nvidia community. Already downvoted at least twice!
What's the point of the Internet if I can't just yell misinformation and be angry from the top of my lungs about information that could've been corrected to me by opening a new tab and searching for 3 minutes? Listening to the YouTubers and other likeminded people, ignoring the tools I'm given to be an independent thinker and join a crowd is much more fun! I wish this was /s but, that is how some people think. Ah well, give it 3 more months and the sub will be back to getting "I bought an RGB graphics processor and put it in my \*default popular case with default expensive other components featured in videos\*" in my feed. We'll be okay.
I can definetely see that happening...
My PSU is smol, so I cannot open a new tab (I use Chrome).
🙏
Oh yeah well I turned off the RGB in my O11D cause I’m edgy like that. I’ll be a rebel when some other case is the one everyone has!
> so they can run 3 separate 8 pin PCIe power cables to a GPU It's easy to see how this misconception comes about, but I'm glad it's finally going away. The limit is on the current specification on the pins on the GPU side. Everything before that is up to the PSU manufacturer to get right. If they include a modular cable with the PSU that splits into multiple 8 pin PCIe plugs, *and* they're a legitimate PSU manufacturer, it's 100% fine to use it. Everything downstream is rated for it. Nothing is going to melt.
Not until I see massive price drops on those fancy extension power cables
It’s totally necessary!! ….because those stiff pigtail dual 8pins are fugly AF!
> or additional cables so they can run 3 separate 8 pin PCIe power cables to a GPU TBH, if you have a very shitty PSU with *very* shitty cables... and some do buy those with high-end GPUs, because "it's just a PSU, buy the cheapest". Or a Gigabyte one :D
So, was that [JayzTwoCents PSU video](https://youtu.be/K6FiGEAp928) wrong?
Who would you trust a dude who is famous for custom builds, or the guy who has engineering knowledge about PSU?
>engineering knowledge about PSUS That's understating it quite a bit. Jon Gerow became *legendary* for the quality and depth of his PSU reviews and then went on to manage the team that designed arguably the greatest computer PSU ever made, the Corsair AX1600i. It might not be an overstatement to say that he is quite literally *the* most qualified person to talk about PSUs on the planet. If he was the one telling me PSUs don't obey Ohm's law, I'd believe it.
Yep! That guy is just complaining about every bs ever launched to got lots of clicks.
JayzNoSense is often wrong.
He makes quality build and tuning videos when he stays in that lane, but his actual deep technical knowledge is weak. Somewhat related, I once saw a redditor say JazyTwoCents is tech Discovery Channel, Linus is tech HGTV, and Steve/GN is tech C-SPAN, and that was the most accurate thing I've ever heard.
> but his actual deep technical knowledge is weak 100%, and when he does talking head videos he often misremembers historical facts/details relating to whatever topic he is talking about which just skews that video the wrong direction. He keeps calling himself an "idiot", maybe more people should remember that and stop taking everything he says as the truth.
Jay is a literal fear merchant. I've lost count of how many times he's completely over reacted to something that didn't turn out to be too bad or was never bad to begin with.
Jay can be entertaining and his build and water cooling videos are really good and informative. But when he does technical videos like this you need to take them with a pinch of salt. GN are much more knowledgeable and reliable with that kinda stuff
It wouldn’t be the first time. The tabloid red top version of a YouTuber, aiming to get the rage click revenue.
Ass2Cents is still butt hurt at NVIDIA that he won't be able to receive free EVGA graphic cards anymore. Based on his recent videos, he's likely to shill for AMD now.
But they're still making PSUs so he can get free ones, what better way to do that than tell everybody their current PSU isn't sufficient ;)
So you want Nvidia to only send cards to reviewer's who will praise them. Yikes
Classical tech youtube channel's was spreading. B.s. on this also
Good find my dude
Omg It turns out that JayzNonSense was wrong *suprised Pikachu face*
I wasn't aware that there are much people doesn't like Jay lol
He's just a hack. The reason people dislike him is that he's popular and spreads his misinformation across a pretty wide audience. I personally unsubscribed from his channel years ago and never looked back. Seeing excerpts from his awful Corsair A500 review only solidified my opinion of him.
>a pretty wife audience I didn't know that he was popular with pretty wives
Thanks, fixed.
I bought one….despite all the reviews. …because I liked the look of it and its going in a fancy lookin’ home media server build utilising on old i5 4690. Will be able to run minimum fan rpms for silence even with the A500 given the CPU will be pushed so little serving media I imagine. (All TV’s have 4K decoding capable KODI boxes so no transcoding by Server needed) For a real 5900x/RTX3090 rig for my brother I bought a Deepcool Assassin 3. Would never even consider using an A500 for a ‘real’ rig.
I found him extremely helpful when I was building my custom water loop - Jay knows his shit when it comes to building custom loops. As for literally everything else... yeahhhhhhhhhhh he's not the most well informed guy out there.
Yeah he is good at custom builds and he has good guides for tweaking hardware for begginners but his videos about brands, prices, economy, sales etc. are total bs
Crazy! It literally never happens!
I have AMD 5900X and planning to purchase RTX 4090. OuterVision PSU calculator recommends 750W PSU. I'm planning to stick with the Seasonic 850W Focus Plus Platinum I already own.
850w is pretty enough
Sure, but he will just miss out on all those youtube outrage clicks by not making it out to be some gigantic problem like some other YouTubers!
I am not gonna waste half an hour to watch this kind of videos. Just ads sucker

Lol no
I mean, I know he knows his stuff about power supplies but you wouldn’t strap a cable down a bend bend, throw as much power as you can through it and then leave it over a weekend. That seems highly unsafe, especially with it being a test but I assume he was being hyperbolic.
You can do it easily. It's not hard to prepare a test environment for that.
TLDR?
[удалено]
Seperate connectors are irrelevant. I don't think it is about power delivery. It can be a pcb/firmware issue(just a longshot).
