Yes.

Yes, they both do. Not well, but they do. I have a Phenom 9600 and an Asus M3A
motherboard. I just got those a couple of months ago.

Haven't gotten that far yet.

I know that the power supply is sending power as far as the motherboard. But
it's either not getting the signal back from the board to power on up, or it's
defective. So, it really could be any of the three.

I'd better, because it's what I do for a living. And all my home systems, except
for the two Apples, are ones I built.

This board actually has a 24-pin and a 4-pin 12v, IIRC - I've been pretty tired
lately, so it's a bit foggy right now.
They were in place, yes. the 4-pin 12v connector *has* to be used as the system
won't boot without it, according to the manual (yes, I know it's against
tradition to actually *read* the manual, but I do anyway, sometimes.) The PS
actually comes with a lead that has *two* four-pin 12v connectors at the end,
but I tried both and still nothing.

I'll test with the original PS and CPU tonight - if I have time.

Thanks. :)
