I have an Antec 850W PSU (this one to be exact)

and My current GPU setup is 2 GTS 250's in SLI. Now my current plan for the summer is to upgrade to either a GTX 560Ti SLI or a GTX570 SLI. I also want to keep one GTS 250 card as a dedicated PhysX card. (i have 3 slots in my mobo) Can my PSU take all of this??? My i7 930 is OC'd to 4.0ghz @ 1.27V and my RAM is OC'd to 1600mhz @ 6-8-6-18 timing config. Thank you!

Well, gtx 560 Ti's draw 170w each
570s draw 219w each,
gtx 250 150w each.
So, 570 sli and a 250 would be 588w.
and 560 sli plus a 250 would be 490w.
Most-power scenario would be the 570s and a 250, which would leave 262w for the rest of the computer. I wouldn't risk it, even though Antec is one of the best PSU makers ever.
I would think that leaving 360w by using the 560s would be okay, though.

Hah alright thank you for the replys. Ill prolly either do the GTX560 in SLI + GTS250. or just scrap it and buy the GTX570's in SLI.
