I just bought another power supply (Antec 550watts) and tried it, with the same thing happening. So now I'm leaning towards another motherboard problem.
Even though I am now suspicious of the P5W since mine has done the weird power down thing once or twice - in your case since it happens every time, with two boards in a row (and so many people have success with this board), I would have to guess, probability-wise, that it isn't the board. If you have two brand new sticks of RAM and have tried each by itself, then probability wise you would think it's not that either. You've tried two PSU's also, so it seems exponentially less likely that either your PSU, mobo, or RAM are at fault.
That leaves the CPU.
Although I'll admit I'm still suspicious of the mobo. And there is a ridiculously unlikely chance that your BIOS is not as new as the sticker on the chip says. But again, unlikely.
You need some way to prove one by one which components AREN'T at fault, though that's probably easier said than done, unless you have a computer hardware store in your closet. That what sucks about putting a bunch of new hardware together - too many variables.
