Yes, that power supply is more than enough to run a GTX 570. I'm running one fine with my TX750.

Since you use a Corsair you should use their own watt calculator

GTX460 runs good on a VX450W according to their site and it does.

i'd take real world experience over any watt calculator.. and wholeeo just told you he has 2x 570's on a HX750 so you should easily be fine on a HX850
