Corsair HX850

post #1 of 8
Thread Starter 
Hey all, just wanted to know if I added a 2nd 5870 would this psu be enough to power it comfortably? I went on one of those PSU recc websites and it said I needed a 1200 watt......this can't be right .......right?

PSU calculators are junk, and inaccurate.

That PSU will be more than enough. You could do that on a quality 650W.

You should be all set.

You should check out that Antec PSU Calc which is a bit better than the rest.
