Verify Power to Motherboard
The motherboard will turn on power supply.
If your game has no 12 volts, it may be the motherboard not turning on.

Minimize load on power supply and isolate short
Unplug all outputs from power supply except for motherboard.
This will have power supply, motherboard, and monitor left plugged in.
If power supply, motherboard, and monitor now turn on:
Plug in one component at a time to power supply to locate short.
