btw here's the best stable 1080p valley run I got out of my 760 so far
1320/1882 with 2500k @ 4.5

I had 460's before this in SLI and my power usage, if anything, seems lower now. Keep in mind that was comparing 460 SOC's (super-high factory overclocks) versus my 760's at stock. In Valley I'm pulling about 530W maximum (UPS reading), usually 516W, 500W+ either way. In 3DMark's Fire Strike I seemed to pull more, up to 580-590W peak, and under a true heavy load (Kombustor with CPU in use) I definitely hit 618-630W or so. This compares to 580W I hit in Shogun 2: Total War on my 460's at max (which should match up well to Fire Strike power usage). Although I'm running a 750W PSU, it was tested in the factory to be stable up to 810W (edit, oops) usage (PC Power & Cooling's individual in-box report). In other words, a true quality 650W should be just enough for you as it has more overhead than it states (actually I run a ton of stuff, lol) and keeping in mind the UPS reading doesn't account for PSU efficiency.
tl;dr I've seen quality 650's power 670's in SLI and these are the same wattage, you might just have to keep an eye on your OC.Edited by NewMaxx - 7/2/13 at 3:25pm
