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'
Yeah. Even when the multi-rails are powerful enough to run mining gear by spec, I seem to have much more problems with multi-rail then single rail PSUs. I'd go for a 1200 Corsair over a 1500 Enermax any day. And I'd go for a server PSU over both =)
Over on the KNC board there are several complaints that the Corsair AX1200i's are shutting down at startup presumably because of the protection mechanism built into the PSU.
I have the same issue using a Corsair 1200i power supply. After a couple of minutes the power supply shuts down. What did KNC tell you to do? This is one of the best power supplies out there this is very odd.
