im running 2 antminers perfectly with a 1000 W PSU
My antminer showed up on time but my powersupply was a day late because of FedEx. So I took one of my GPU miners, disconnected a 7950, and used those two PCI-e leads to run the antminer. It ran that way until late the next day when I finally received my new Corsair TX850M to run the antminer. All is running good.
I am waiting for my group 3 antminer to show up now. I pulled an old Dell 4u dual xeon system and a old supermicro 4u dual xeon server that I used as database servers many years ago. They both have dual hot swap power supplies in them. I am working on connections to put these to use with ASIC miners. I have a few 1u and 2u servers in storage, I'll have to see if I can use them also.
Not good. Never heard of the units _killing_ PSUs. I guess these are armyantminers. As far as the bent back plate, yeah that thing is really thin and prone to bending. One of my units came with the fan grill all pushed and bent in. As you can guess I did not spot it right away and when I powered the unit the fan made a loud grinding noise as it was stopped dead in its track by the bent grill. A pair of pliers did the trick and all is well now.
