Currently I use my GTX 580 for folding overclocked to 900 core @ 1.15v. Even though the TDP is 244w I think it only draws ~105-110W according to GPU-Z. Usually I don't use my CPU at all when folding. But I wanted to add a GTS 450 to help my PPD as it seems like the best deal for the money (~60 used on ebay). Will my corsair 650tx be able to handle both cards and my CPU at full load?
Also, if i do get it, would the gts 450 make a decent physx card in games that support it? (I realize this question wouldn't belong under the psu sub-forum but it does save me having to start 2 threads)

Thanks

Yes and yes.

you should be fine, Worst case 200 watts for OC cpu, ~225 watts for the gpu, ~120 watts for the gts 450, leaves you about ~100 watts for the rest the system

Edit: and yes, will do fine for physx

It'll be Fine, My work computer uses a 300 watt power-supply that came with the computer, and I don't run anything at the factory clocks.... it runs perfectly fine.
