What Power Supply for 2 x 8800 GTX cards ?

[Hawkwind]

I just ordered two 8800 GTX cards for SLI. Apparently (I am reliably told) I will need a big juicy power supply.... any idea just how juicy ?

nice buy! 750Watt thermaltake tough series should do, please wait for more responses than me tho ;) im new to the PSU advise

depends on what brand.

with a well recognised brand, even 650w will do. my Corsair Hx620w can even do 8800GTX in SLi.

but with a value brand, you'd be lucky if 1000w runs it
