2 psu for 1 computer connected to different stuff?

I don't see why you wouldn't just use one power supply. You can find 24pin to 20 pin adapters for around $10 at newegg.com. But you would be able to use two, but you would have to manually start the power supply that is not connected to the motherboard. To do this, I suggest watching this video (a href="http://www.youtube.com/watch?v=u0OKmIuNtmI)." rel="nofollow"http://www.youtube.com/watch?v=u0OKmIuNt…/a You will need to do this every time you boot your computer, so I strongly recommend that you use a single power supply.
