EVGA vs. Corsair

[F Bomb29]

So I am currently looking into a new PSU and I was thinking either the AX1200i from Corsair or the SuperNOVA 1200 P2 from EVGA. Which one would be the better PSU? I plan on putting in 2 1080s and a custom water cooling loop for CPU and both GPUs. There will be 2 radiators both on push/pull, and one D5 pump/res combo from EK. With the Cooler Master PSU calculator it recommended having 938 watts so I decided to go a little higher wattage just in case.

 

Thanks

Either.  Get the one with the features you like.  They're both good.

The Cooler Master calculator is complete bullshit.. why do people still use it...

 

The two 1080s in SLI with a 5960X would use no more than 600W under load and you definitely don't need a 1200W PSU for that...

 

Nonetheless, the EVGA 1050G (under the GS moniker minus the S for some reason) would do you nicely as well as the 1000W G2. No need for 1200W.

 

Of the two you chose both are so damn good you should get the cheaper of the two, but only if you had four 1080s in SLI.

They are both very good PSUs, go with whatever you like or is cheapest. 1200W is way overkill, a 700W/750W would be fine for two 1080s in SLI.

Both are fine choices but Corsair looks nice IMO.

Completely stock with no CPU or GPUs overclocks, maybe.  Definitely not with all running a decent overclock.

Thats what i'm thinking, I'll have both cards overclocked and currently I'm sitting at 4.3GHz @1.3v on my CPU.

Even with an overclock they won't exceed 650W. Two 980tis with overclocks use about that much.

You could easily run with an EVGA G2 850 or a Corsair RM850x.

Eh, an overclocked 5960X isn't really the easiest on power.

With a heavily overclocked 3960X (more power hungry than most CPUs) and three GTX 980s Guru3D's test bed used 589W from the wall http://www.guru3d.com/articles_pages/geforce_gtx_980_sli_review,4.html

 

Add 200W for overclocking all three cards and you're still well under the threshold.

OPs got a 6800k which uses less power than the Sandy Bridge E chip Guru3D used in the link I posted above.

Definitely not trying to call you out bud, but your passing some misinformation so take it how you want.  When I had a 980 Ti SLI, I hit peak draws from the wall in the area of 1075w.  These were only peaks and not average consumption.  

 

My 1080s are obviously better, but I still would never run a 600w to 650w PSU to my current setup.  Can you get away with doing so, maybe, but is it good practice?  Hell no.

I do agree that his setup will use less than mine.  I was just addressing your first comments about a 5960x.

Lol, I wanna know how you got that figure  Did you calculate efficiency of your PSU and also count in everything that was plugged into the wall? I highly doubt your readout was correct there. Whatever you had reading out didn't factor that correctly or you had everything plugged into the socket and/or didn't factor in efficiency of your PSU which plays a big figure in power draw. Trust me when I saw this, you were not borrowing 1000W from your PSU

It's very obvious that your basing your posts on what you've read hear or heard there.  What I am telling you is that it was measured at the wall.  It's really that simple.

In fact, I'd recommend the 850 G2 (IRC it was one of the few 10/10 from JG). I pull right up to the limit under full stress two 980ti's over-volted custom bios, but gaming loads are more like 600W or so, and the two 1080s should draw about 150W less total so it would probably be right under the sweet spot for that PSU (given the 5960x will draw a bit more power than a 5820k)

The only time I ever have had issues was trying to do F@H (I did actually overpower shutdown a few times before I gave up) for both GPUs and CPU (and that is custom bios GPUs running at 350W power target), that said I would expect the 5960x to draw about 50W more under load than my 5820k did (which is easily offset by the 150-200 W less underload two 1080s overclocked will run since they don't really improve that much at all relative to GM200 with more power). 850W is a good sweetspot, I wouldn't touch less than 750W though just in case.

 

Using a T2 that wall peak looks like about a 950W at the psu peak which I guess makes sense if all loads I was pulling over 850W spikes and you were using a hotter cpu.

This is straight from the Asus guys like Raja.

1000W doesn't seem too awful for a minimum recommendation from a manufacturer. If someone else had my pc and they weren't tech savy, I might have recommended them a 1000W instead of the 850W I bought (I tried to talk a friend who is aircooling a 980ti and a 4790k into swapping his 1000W G2 for my 850W G2, but he wasn't interested.)

Agreed.

 

I hate being this far off topic, but couldn't resist pointing out how wrong assumptions can be.  So Asus says that 400w or more can flow through the 5960x while overclocked as low as 4.4 GHz.  Digital Storm has similar dramatic increases in CPU power draw once the 5960x was overclocked.

 

Back on topic.  @F Bomb29, stick with 850w to 1000w and call it a day bud.  That 6800k and 1080s deserve it.

In fairness that is whole system power, which means the cpu is probably drawing closer to 300-350W, but point remains.

That was the 550 G2 that got all 10 points.

Either way, it's easily a great PSU.

Thanks, I decided to take your suggestion and go with the RM1000x. I hope that one works fine.
