This efficient power supply can run two 8800 GTX in SLI.
Essentially this is Seasonic power supply with a Corsair badge whacked on.

wow, that looks like a damn nice psu

I was looking at

http://www.ebuyer.com/UK/product/114941

however evga are not very specific,

i.e. they ask for 26amps on 12v psu, and as their site is aimed at the end user whether in/competant one would assume they mean 26amps on a single rail, because most end users will not know that a psu can have multiple rails/ and there is no mention of this on their site
