So, the PSU runs and what happens? Do the case fans run too, does the hard drive spin up? Does the CPU fan run?

Does it beep when it turns on, does it stay on, or does it turn off after a few seconds?

What exactly happened when your first PSU "died"?

Triple check all your wiring.
If it is not beeping, and the CPU fan doesn't spin, then I think you should check the CPU first for any signs of fried goo. If it looks clean, it could be the motherboard that was fried with it, try your CPU on another computer, if it works, try your hard drive on another, then video card.

Just from the information now, I think it's the motherboard, but you should probably wait until tomorrow when more people are on.
