PSU problems - not enough load on it to run?

Hi guys - hope someone can help, this has been driving me nuts for days. I've got the RMA form filled out but wanted to check here before I post the PSU off.

Just to start, I've read through that helpful post at http://www.tomshardware.co.uk/forum/261145-31-perform-steps-posting-post-boot-video-problems while I was reading through the other posts.

Okay, the PSU is an Enermax Platimax 1350W and the motherboard is the ASUS PT6 SE. PSU is a monster and had it for running multiple GPU's on another rig where it DID work before trying to move it into this computer.

The motherboard is fine as it's working with another PSU on the computer that I'm writing this email from :)

The PSU only seems to start up the CPU heatsink fan for a second then stops. The PSU fan itself starts and runs for about 20 seconds before stopping.

I've got the PSU also running by itself with a the yellow and black wires in a molex connector plugged into the red and black wires on a little heatsink fan that came with a little 45W CPU - I've got the paperclip trick to get it to start but it's doing the same thing that it was doing when connected to the motherboard, that fan starts moving then stopping.

Any ideas guys? A great PSU wrecked? Or just not enough load on it to get things moving (total guess!)?

All suggestions more than welcome :)
Thanks in advance,
Andrew
