Hello everyone, I need help deciding what to get. I just purchased the coolermaster 1200w psu for my rig in my signature from newegg at 180 AR as an upgrade from my 750W PC Power. With the dual 6970 setup I have 1100 W seems just right with 30% capacitor aging. However should I decide to add another 6970 and do 3 way crossfire, I will be at 1350W according to the PSU calculator at coolermaster. Plan on a 4.8 ghz overclock with the 3930k. The enermax maxrevo seems to be better suited for future growth, and I have seen it come on sale for around the 210 mark.

What should I do, keep the 1200W or return it and get the 1350W?

System

Case: Corsair 780T Black
Motherboard: MSI X99 Godlike Gaming Carbon
CPU: 6800k overclocked to 4.2 ghz @ 1.42v @ 55c load temp
Video Cards: 2x MSI GTX 1080 EK X in SLI
RAM: GSkill 64 GB (4x16 GB) DDR4 3200 cas 14
Drives:
Samsung 960 Pro nvme 512 GB (OS and programs)
Seagate 7200 rpm 6 TB (Data)
Cooling: Custom 4 radiator EKWB loop

Wow, that is a terrible calculator, dual 6970's call for at most a 750 watt PSU. Capacitor aging is of no concern with quality power supplies until they become at least, say, a decade old. A 1200 watt PSU is needed for quad SLI GTX 480's under heavy overclocking, not for just two 6970's. A third 6970 would call for an 850-950 watt PSU.

i agree. your current PSU is a good choice, id just stick with that unless for some reason it causes you problems. i had a cm PSU in my last build and it was awesome for the 5 years i used it.

You are fine with your current setup. That system would run fine on 850w.

Yeah the 1200W is more then enough,

I'm running 2 pumps, 2 8ch fan control, 2600k and 6990 + 6970 from a 1000W unit, and my HDD's and dvd drive from a 620W unit.
all toghether out the of the wall it pulls 1050W~ running prime95 and heaven2.5.
edit : My overclocks are [email protected] 4.7ghz 1.4v and the 3 gpu's at 1.3v

Thanks. The SB-Es are power hungry compared to the 2500/2600s, but I'm currently managing with my 750W, I'll hang on to the 1200.

Yeah thats true, but its only a 95W to 135W difference, inlude an overclock and you will have some more, but not 150W + over the 1200 your already using. just my 2ct.

lolwut.


2 580's will run with a good 850W PSU, and believe me they love their power.


Stick with your current PSU, they report artificial power draws, extracted from artificial benchmarks such as furmark. Even then is that power draw exaggerated.
