Turning on an ATX psu.

[SirFrags]

I have an ATX power supply I want to turn on that is not hooked up to a motherborad, all the information I can find leads me to believe that I need to use a 'TTL' circuit. If this is untrue, how else can I turn on the supply? If it is true, does anyone know where I could buy one or get a schematic / instructions on how to build one? I am looking for a permanent solution; I read one site that suggested connecting PS_ON# and a common pin, but it also said this could damage the power supply if done often.

Thanks for your time,

You can find information here:

Just for testing fans or power supply, I jumper the green wire to a black wire at atx connector. You need a fan connected to a molex for power supply to work, install jumper before plugging in power supply.

I just stick my pliers into 2 pins, works perfectly fine for me, always has!

I use a paper clip.

I couldnt find anything and saw these twisted pair offcuts on my desk, hey! they work ok!
