Use this to "do the math"

don't forget external USB's fans etc.

With two GFX and > moderate OC'ing I'd use an 650 - 850 watter off the Editor's Choice list (rated for electrical stability and quietness) here:

http://www.silentpcreview.com/Recommended_PSUs

Antec Signature 650 (and 850)
Enermax Modu82+ 625W
Seasonic X-650
Seasonic M12D 850W
Antec CP-850 (fits only w/ the 1200, 183 or 193 Antec cases)

If moderate overclocking (20 % or less) , the "Recommended list" is fine

Corsair HX/TX650W
SilverStone Decathlon DA700
Coolermaster Silent Pro M700W
