It occurred to me very recently, that after my recent computer upgrade rather than storing my old GPU on a dusty shelf, I can still use it in my computer.

While I can't do SLI on account of only a single x16 PCI slot (and a shitty second card), I should still be able to use my old card as a dedicated PhysX card in the 8x or 4x slots. It's not much, but it's always something.

The question is however, do I have enough power? Currently the system is powered by a 650 watt Cooler Master PSU.

Things that munch on voltage: Core 2 Quad Q9550 GTX 275 1 SATA Hard Drive 1 CD/DVD+RW Drive 4x 1GB Ram

If I were to add a single 8800 GT to that setup, would my PSU be able to handle the load, or give out under the strain? Ive tried several online PSU calculators, but none of them seem to consider the posibility of a dedicated PhysX processor.

You've got more than enough.
