editpulled one miner off the hub, and ran 2 at 450mhz and it got pretty stable (running dec18 build), anything lower than that i get resets and missing nonce
i guess i need more power to run 3...
it is a low quality psu. or at best medium quality it has 2 rails for 12 volts. each are 22 amps so you could have the pcie jack pulling on a 22 amp rail along with the mobo using that rail. which would mean you do not get a full 22 amps to pull on.. 22 x 12 = 264 watts which seems enough but if the mobo and the pcie jack share a rail
and the cpu pulls on the other 12 volt rail using the cpu cable. in both case you are pulling on limited power amp wise
ATX12V v2.3 / EPS12V
80 PLUS BRONZE Certified
100 - 240 V 47 - 63 Hz
+3.3V@24A, +5V@24A,
+12V1@22A, +12V2@22A,
-12V@0.8A, +5VSB@2.5A
so one rail send say 12 amps to the mobo and the other rail send 12 amps to the cpu cable
this means at best there is only 10 amps left on either rail for your gear.
this gear is a much better fit for you
