Hi, I was wondering what size PSU I should be getting?
System I am almost done putting together:
ASUS p8z77-v deluxe MB,
16GB SSD 1.25v 1600 ram
680 GTX vid card(maybe someday I will get another for SLI, maybe never.. who knows)
Corsair H100 Water Cooling
1x3TB seagate HD
1x500GB WD HD
750 is the minimum recommended (http://www.guru3d.com/article/geforce-gtx-680-sli-revie...) for GTX680 SLI, so it more than likely would, as long as you balance the load properly across the 4-rails (vs. the 1 on the Corsair which negates the need balance.) The PSU is just such a critical component for everything, that I would happily spend more on a quality well made piece (OCZ isn't "bad", but there are better PSU vendors) versus things like an H100 over comparable/better air cooling at a lower price.
Also that PSUs typically are more typically more efficient at a lower load % and there can even be some (very small) energy savings.
