So do you have both cards running at once? You didn't make that clear, If you have 1 Card running, 550 Watts will do, But if you have 2 In SLI 750 Will suffice.
And just so you know don't buy Corsair CX Series PSU's, They have bad capacitors that burn up fairly quick.

Thermal and Power Specs
Maximum Graphics Card Power (W) = 116 W
Supplementary Power Connectors = One 6-pin


So 600 watts for the system + 116 watts for the PhysX card .... will need one 8 pin and two 6 pin connectors

Id go for a good 650 watt power supply. That should be plenty to handle that rig. 750 if you lean to the "PSU Overkill" crowd like I do.

Which graphics cards can accelerate NVIDIA PhysX?

If you intend to use an NVIDIA supported graphics card [i.e. 550 Ti] as a dedicated Physx card, the other graphics cards [i.e. 770] in the system must also use an NVIDIA GPU.
