Compatibility issues - need quick advice

I just got got a new power supply, and I'm wondering where I can confirm that it is compatible with both my motherboard and graphics card. I'm pretty sure it's compatible, but am having trouble confirming. The power supply is the rocketfish RF-500WPS2, my graphics card is the geforce 8600 gt, and the motherboard is the amd athlon 64 x2 dual core 5000+ 2.60GHz.

If anyone knows off hand if these are compatible or if I would have any problems, or a webpage that would lay it out for me it would be appreciated.

thanks, i appreciate it.

Power supply is in, but now when I switch my old ATI radeion x1650graphics card for the nvidia geforce 8600gt, it seems to go in and work properlly, but my monitor is not getting any singnal at all from my PC. Any ideas?

yeah, the chords are plugged in. I tried uninstalling the drivers for the old card, then installing the new ones, but i got a message saying the new drivers couldnt be installed because the hardware wasnt present(i was doing this with the old ati card in) so i shut it down, put the nvidia card in but again got no signal so i couldnt install the drivers.

any other theories?
