Update:
I tried one of my antminer 1600 watt PSUs and there was no change. Seems weird... I can try to contact zoomhash to see if they can offer any help.
Any other thoughts?
If you know that PSU is good then its still something power related - a short maybe. This is why resellers are a bad idea, they're buying the product exactly the same as you but passing on problems and responsibilities. Buy from the source whenever possible.
