PSU ATX power off

As soon as i switch on my PC after a second it switches off. I have determined that by unplugging the 4 way 12v ATX P4 cable the PSU stays on. Any ideas what can be occurring when the cable is plugged in? Thanks

Re: PSU ATX power off

Either Power or Heat, Unplugging the CPU power plug will lighten the load on the PSU, also because the CPU isn't powered up it won't heat up.
Try unplugging the drives and and USB devices except the Keyboard/Mouse see if you get into the Bios.
