How much power do I need?

[CefiroZ]

I'm putting together a few dedicated rendering machines that will basically be composed of a box (microATX or more likely Shuttle), mobo, single hard drive, cd drive, and the graphics card. The graphics card will be a high-end NVIDIA card of some sort. What size power supply do you think I'd need to drive this setup if the nvidia card is a single card solution and if it is an X2 solution? I'm looking at Shuttle boxes on Newegg but can only seem to find them with 400W PS max.

no, no, no.....size, heat, not good idea in any way shape or form. if you're intent on a shuttle, your best bet will be an ati 3870 or 3850. nvidia 8800gt will blow heat back into your case, and both gtx and gts 512 are too big and too hot for a shuttle. psu output will be the least of your worries.

Yeah it would be an oven. My first 8800gt was in a Matx Dell Vostro 400 and I had to add a intake and pci fan to put my mind at ease. It was still to hot for me.
