Peeps....
I thought every miner knew....

You should only use SINGLE RAIL PSU'S
anything else you are wasting $ and taking huge risks imho

Multi-rail PSU's are SHIT,
I burnt out a couple last Generation before going to all Corsair single-rail
Even when the multi's "worked", they could not keep up with the rest
Even 5 year old-crappy used HP desktop PSU's were better. Just sayin'
