Best solution
There could be a number of possibilities. Before ruling your computer dead, try the following:
1. Plug it in to a different outlet
2. Use a different power cable from wall/outlet to PSU
3. Disconnect the P1 connector from the motherboard, and then stick a paper clip in the green wire pin socket and any neighboring black wire pin socket
4. Check the motherboard for signs of damaged components (I.E. popped capacitors)
5. Use a known working PSU
6. Check voltages at molex connectors, if using a known working PSU. Yellow wires should be at about +12v.
7. check voltages at P1 connector, while it's connected to the motherboard.

I would replace them all. The chemical composition is the same in all of them, so chances are high that others have failed, even though there is no physical sign of damage. Sometimes the capacitors dry up on the inside.
Also look for leaking capacitors, and not just at the top, either. Look closely at the bottoms. If you see any dried substance in orange, gray, brown, white, or black, it probably means the capacitor(s) next to the discharge have leaked.
