Hey Guys!

I know the GTX 790 hasn't been released yet, but I definitely want to pick one up as soon as it is! I just want to know, if this is possible, do you guys think it'd be possible to run two of these in SLI with a Corsair RM Series 850 Watt PSU? My other specs are here:

i7 4930k @ stock
Corsair H80i
16 GB Corsair Vengeance 2400MHz
Will probably have a few (3-4) SSDs/HDDs when I buy the cards
EVGA X79 Dark Motherboard

Thanks a ton!
 
Solution
The GTX 770 has a TDP of about 230W. If your imaginary GTX 790 is two 770 on one board, two cards would eat 920W.

The rest of the system also needs power.

So I suggest a 1200W or better.
