Hi there,

I'd like to test a new PSU (just the output voltage) without putting my mobo at risk.

Which wires should I connect together on P1?

The problem here is you need a load on the psu to prevent cooking, put an old hard drive or some other useless item on the unit before firing it up.

Oh and

To turn on an ATX power supply without having to plug it to a motherboard, just ground the PS-ON signal from the power supply, i.e. conect the PS-ON signal (pin 14) to ground (pins 3, 5, 7, 13, 15, 16 or 17). Usually the PS-ON is connected to a green wire, so you will have to conect the power suply's green wire to the black wire, through a small wire or an opened paper clip.

or just...
jump the green and any black wire with a paperclip or some other conductive material (wires, etc...) and it'll fire up.

Though I would be carefull

Cheers

You need to load the supply, I'd make sure you have at least a 2 amp load on the +12 and the +5 before you fire it up.
