My System Specs

Default

Just looking at the power numbers between my previous 560ti SLI setup and the stock 480 from the original review here has me wondering about a 1K PSU for your current setup.

I was pulling over 600W (as reported by my UPS) with my current 920 OC + 2 560ti OC cards (stock OC). Looking at the 480 power numbers, I'd expect a pair of them would add an extra 75W / card so at least an extra 150W which puts you into 750W+ draw under full draw (when I say full draw, I mean 100% FAH both GPU and CPU) which to me doesn't leave a lot of overhead on even a good 1K unit.

I know many folks here will say that I'm crazy to suggest that even a good 1K might be pushing the limit for a heavily OC'd 480 SLI setup, but I personally want as close to 50% overhead and 40% is my comfort zone.
