GTX 460 sli PSU?
 
Im going to be running two GTX 460 1GB in sli for Battlefield 3 Is a 850watt Psu enough power or should i go with the 1000watt?

850watt is more than enough to power 460's in sli

I have 750w with the 460s over clocked to 800mhz and I have no issues, I doubt I'm much over 600w.

What did you overclock them with?

850w is more then enough...assuming it's not a cheapy 850w. What PSU is it?

Probably MSI Afterburner, with a bios mod.

If you're over 600w there is something terribly wrong, or you're extremely overclocked on both your CPU and GPU cores. From memory my i7 920 @ 4.2 and 2x460's @900mhz+ (bios modded) were pulling about 460-480 from the wall while folding on everything.

Corsair HX650 should be enough to run both cards, from your specs you have a 1000W PSU now so why you worrying about PSU.

FWIW my other rig has two gtx 460 in SLI with a HX620 and IMHO that is plenty. A quality 600W should and will not have any issues, Anything more than that is just gravy.
