Motherboard Power Supply Port

[invertedflight]

Hello,

I just bought a cheap computer power supply to be used for circuit prototyping (not in a computer). This means I want to simply plug it into a wall outlet and use the 5v, 12v, etc. outputs that it has. The problem is that I can't activate these outputs because I don't know anything about the master plug that plugs into the motherboard. I'm assuming that pulling one of the pins high will activate the power to the rest of the cables, but I don't want to just mindless probe the pins. I'm having trouble finding info online, so if someone can point me to the documentation I need that would be very helpful (doesn't really matter, but the power supply is an Enermax EG301P-VB).

Thanks a lot,
Chris Hansen
