If nothing is 'blown', then it may just be the startup resistors, which are required for the supply to start, then it feeds itself.

Look for a couple of highish value resistors, they usually use two in series (which is probably why they fail) - they go high or O/C.

If you are trying to run it outside of the computer case, it might need a load to start up, or the green wire on the motherboard connector needs to be connected to ground.
