Any of you gentlemen (or ladies) running 2x SLI 580s on an 850W power supply without issues? I understand the 580s are power hogs and question if I need to go to 1000W to run BF3 full stop.
Thanks for the links and feedback, folks. I do like to overclock my CPUs and GPUs. 850W seems marginal if BF3 runs at load similar to Crysis. I may just wait until the 7970s become more available and xfire 2 of those. They seem to require 100 to 200 less wattage. I can sell the 580 and squeeze a little more performance out of the system for not much more cash.
I am running 2 GTX 580 MSI Lightning Xtreme cards on an AX850 without any issues. I don't have them overclocked but my 2600k is overclocked to 4.2GHz at 1.28V.
What kind of framesrates are you getting?
I think you will even be fine as long as you are not overclocking an AMD FX CPU. I would invest in a $17 Killawatt just to make sure you are not exceeding the continuous power rating of that PSU.
