Can my power supply hold this GPU unit?

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.

it's an excellent PSU and you will be fine with the GTX560 in sli + GTS250

the GTX570 in SLI will also be OK also but the GT250 may just push it too far (it will work but it be too close to the edge). frankly i would just get the GTX 570 in SLI and sell the GTS250.

* A second card requires you to add another ~225 Watts. You need a 750+ Watt power supply unit if you use it in a high-end system (800+ to a KiloWatt is recommended if you plan on any overclocking).

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.
