EVGA PSU dead?

[aisle9]

I have an EVGA Supernova 750 GM (80+Gold) that I think is dead, but not ready to write it off just yet. This unit was an RMA replacement about a year ago for a 650 GM that died on me. I was watching YouTube last night when my computer made a loud click and turned off, then wouldn't turn back on. I put a PSU from a different system in and my PC works fine now, but I'm not sure if the EVGA PSU is truly dead. I connected it to an old system I have here, and when I connect it and try to turn the system on, it clicks, the fans kick in for a second, then it just dies. Doesn't even make it to full speed, just a pulse of power. Pressing the PC's power button again doesn't do anything. It's definitely delivering power to the board (green light is on), just dying instantly. Video below. Is this PSU as toast as its deceased predecessor, or is there something I can do to bring it back to life?

Sounds dead I'm afraid.

It might be shorting somewhere. I'd try with one more fully stable functioning PC before ultimately coming to the conclusion that it indeed is dead.
