Google it.

BTW, there is no -5V.
Be careful.

Check JABBA's Supergun page -- he talks about cnonnecting a PC power supply to a JAMMA rig:

Direct link to the Microsot Word DOC containing his instructions:

NOTE: Don't rely on wire colours -- use a multmeter to test voltages!

Cheers.

Sorry to just jump in... long time lurker, only posted a couple of times...

PC power supplies do have -5v, not off the connectors to components (hd, cdrom, etc)
but there is -5v on the motherboard connector...

Here's the motherboard connector pinout for an AT power supply...

That's an outdated AT power supply, though. What about ATX?

FWIW, I would use an AT over an ATX in this application everytime. No need to short pins.

But, here is the ATX pinout:
