I have a corsair rm850 psu and one gtx 780 at the moment. I also have a i7 4700k at stock spped if that helps. But i was wondering if my 850w psu would be enough to power 2 780's in sli if i wanted to upgrade?
thanks

Yes, that's plenty of power for SLI'd 780s.

On a side note, great choice in PSUs.

I wouldn't do it, 850W is fine if the unit is high quality, but that unit uses capacitors that don't like high loads: http://www.jonnyguru.com/modules.php?name=NDReviews&op=...


I had a Corsair AX860 for my Titan Blacks (which consume less power than a 780 Ti) and I had issues ranging from lock-ups to freezes and black screens. As soon as I upgraded to my current PSU those issues stopped.

I'd say you are cutting it VERY fine with 850w and would strongly suggest upgrading your PSU.
