EVGA SuperNOVA 850G2 Enough

Hey guys. I plan on watercooling my sig rig below and I was wondering if the EVGA SuperNOVA 850G2 would be enough to effectively power my rig. I do plan on overclocking both GTX 770s and 4670K. Would you guys use this PSU or step up to the EVGA SuperNOVA 1000G2? I did use Xtreme's PSU calculator and it recommended a 775w PSU for this rig with 90% TDP and 15% Capacitor Aging. Thanks.

The 850 would be plenty unless you plan on modding the bios and its power limits and voltage. So long as you stay within those constraints, that 850W PSU will be fine. The 770 is a 275W GPU at worst with stock bios.... and you wont reach that value unless you power virus the thing.

I do plan on modding the bios on both GPUs. The 1000G2 is onle $25 more than the 850G2.

The 850W should still be fine, but for only $25 more, why not.

Alright. Cool. I'll get the 1000G2
