Just an update guys. The Enermax is exibiting some odd shut-off pulses. You can see them as my tester flashes on and off because the tester takes power directly from the PSU.
Video:
That video was taken as I switch the PSU off (you can see my hand) and each pulse is times to a muted "zap" from the PSU.
I have no idea what is causing this but I will hook it up to my multimeter tomorrow.
