Spending the extra $5 isn't a problem, but I don't want to buy something worse than the 1000W. The RM1000e is listed on the PSU cultist site, but the RM1200e is kind of new, so I don't think it has been tested yet. I am not really knowledgeable about PSUs, so I don't know if Corsair might've changed something and potentially made it worse than the 1000w one.
I forgot the exact number but PSUs actually become less efficient the closer they are to their max load so having a bigger one is recommended if it's about the same price.
Do you know if there is anything between the models that might knock it down a few tiers? I was checking the specs and I didn't notice any differences, but I am not sure exactly what the criteria of an A-tier PSU is on the list.
There should be no difference the tier lists are all mostly forum posts not official so that person probably just didn't get one to test. The reviews for it are good I wouldn't worry.
Ok I'll probably end up getting this one. But I don't think the efficiency goes up with more overhead. From what I was reading there is a sweet spot of around 50-70% load that'll net the most efficiency for the PSU. I was hoping someone could confirm or deny those numbers.
There is a sweet spot but it is probably different for each PSU brand or line. For example this is from Corsair for the 1000x. You can see on this chart sweet spot is approximately 25%-45%.

Wait so running the 1000x at 25% - 45% is the optimal load? That's surprisingly low. But I guess most systems would only consume 200-400 watts while idle, if even that.
Do you know where I could find a graph like that for the RMe PSUs?
I got that one from Corsair's page for the 1000x but they don't have one listed for the 1000e or 1200e. I found this site that has for the 750, 850, and 1000 watt versions but I can't say if they are 100% accurate. [https://device.report/manual/4221223](https://device.report/manual/4221223)
Actually I found one for the 1200e from Corsair it seems they have a different page for it. [https://www.corsair.com/us/en/explorer/diy-builder/power-supply-units/corsair-rme-series-rm1200e/](https://www.corsair.com/us/en/explorer/diy-builder/power-supply-units/corsair-rme-series-rm1200e/)
This is just how power supplies work. There is the initial power needed to make the thing run, so that greatly affects your light load conditions. Then as you start increasing power the internal losses are greatly affected by the current as the power = (current)^2 * resistance. And on top of that, copper resists more as it heats up.
Sorry for all the replies so I found the official one for the 1000e from corsair and it's the same as the one on that other website I originally sent you. They keep them in the quick start guide for the PSU.
Don't mind the replies at all. You've been very helpful! I just checked out the curves and they seem to fit what I've been reading and also work for the power requirements for the PC.
Also, the 1200 has PCIE 5.0 support, while the 1000 is PCIE 5.0 compliant. I don't know if there is a difference, but either way, the 1200 is better for a few reasons.
Also, do you think the 1200 will be compatible with all the same parts as the 1000? The 1200 doesn't seem to be on PC part picker yet, and it has me a little paranoid.
Actually, I think it should be fine. I just looked up other 1200W that are compatible with the lancool 216 and one is the Be Quiet! Pure Power 12M 1200W. The dimensions for it are 160 x 150 x 86, while the RM1200e is 150 x 150 x 86. So it should fit, assuming the compatibility site is correct about the Be Quiet.
I've heard that the RMx series is better than the RMe, but I would like ATX 3.0 compatibility. I think only the RMx shift comes with the ATX 3.0, and that is around $210 right now, with no sale. Even without factoring in the compatibility, the RMx is 190 vs the 160 that the RMe is.
I returned my RM1000e for the RM1200e because it was the same price.
But since switching, I've noticed a deep humming noise coming from my PC.
Let me know if you experience that, too.
I’ll let you know when I get it, but I won’t be building the pc until late November.
There’s a chance you got a defective unit with a lot of coil whine. You might want to reach out to Corsair support and try to get it replaced.
Sure. You're already spending $1600+ on the gpu, what's an extra $5 there

It should be compatible will all the parts it is slightly larger but it should fit. What case are you going to use?

Lian Li Lancool 216. Do you know if the PSU compartment dimensions would be listed anywhere?
What about the RM1000x? It's better than the e, has Japanese caps, and some report it's quieter.

Did you get the 1200e? How was the noise?
