Sick Corsair AX1200i. Please help!

[powernoob]

I have a used Corsair AX1200i Digital Power supply. It was given to me by a friend. RMA is not an optional. When I hook it up to a motherboard it trips instantly. So I started poking around with it. I pulled out all power cables exept wall power and turn it on with a small piece of wire. It will stay on for 20 minutes to an hour and it will trip. Then I plug it back into the board and it starts right up. So I hooked it up to my main system and it turns on for about 3 seconds and trips. It has a self test feature that works somtimes. I can hear a clicking noise coming from the area near where the wall power plugs in. Its an expensive PSU so I dont want to scrap it. Any help would be much appreciated!

Here is a picture I found untill the morning. The clicking sounds are coming from the bottem left side, from the grey rectangular boxes.

The clicking noise when you power it up is from a relay, which bypasses the NTC thermistor once tit has done its job and allowed the primary cap to charge up more slowly. the noise is perfectly normal on this PSU.
