Normally a PSU will not turn on unless it has a reasonable load on the 5v and 12v rails.

Why do you want to 'short' the powersupply?

What kiwiguy is saying is that you need to connect something to the power supply like a motherboard to put a load on the power supply so that it will turn on and not get damaged.

Perhaps in your forum reading you either came across shoring the pins for the front case switch or the jumpers to reset CMOS. Neither seems appropriate here. Any more info you can give. Is this a new build?

As for the issue at hand, have you tried to boot the machine with nothing attached except for video and cpu?

I was thinking that maybe the wires that go on the bottom pins (pwrswitch, reset sw etc) are not in the right way or on the wrong pins. I remember doing that and the machine wouldn't boot up, though there were power. I'm thinking that the POWER SW is not in the right way.
