I haven't built a new machine in many years. Now that I know I want the ATI 6970 (possibly xfire'd x2), what would be the minimum Power supply you'd recommend?

Thanks!

Something that has 70A on the combined +12V rails and have 4 PCI-E connectors, two 6-pin and two 8-pins.

. 750 watts will be ok and the brand should be like corsair,seasonic,antec,xfx,cooler master pro.

Get 850w with 70amps on 12v rail....you need it for 2x 6970s...and you have to keep in mind PSU's lose their ability to maintain the rated power overtime..so 750w might be fine now..but in 2-3yrs its capacity declines. The price difference is minimal.

newegg has a 850w psu from OCZ for $100 today on shellshocker..get it.
