Almost certainly the PSU.  A voltmeter is handy for checking such 
things!  A short circuit on mobo or wiring might also have similar 
symptoms.

ATX PSUs are all pretty much the same so you could do a swap-out.  If 
you really need 400W and don't have another then disconnect some stuff 
before testing with a smaller one.
