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'
Heck my Merc with upgrade module is still running strong on two el cheapo 12v LED 360watt supplies that cost, what, $25 each? Those and a wall wart for the BBB.
