Miner 1 added 55 watts to the total load, miner 2 added 60 and so on and so on.... They are all getting very warm but none of them have crashed. I have them all powered by a single 850 watt Corsair gold rated supply.
Would you mind elaborating on this -- using a single 850 watt corsair PSU?
1. Are you doing both BTC & LTC mining with this PSU?
2. Can you tell me how you wired this up?
Sure.
I'm trying to mine LTC only but as I found out without the controller the miners come up in dual mode even though I only have an LTC pool in my .bat file that starts each miner. Since the miners are supposed to only draw 7-8 watts in single mode only my 850 watt supply is more than enough to power them. As it stands the draw on the supply is close to its limit which is why I only have 9 miners connected to it right now.
I powered the miners by getting 5.5mm x 2.1mm (YES, 2.1) barrel power connectors (not sure what the technical name for them is) and a bunch of 4 pin molex 12" Y adapters. My plan was to power the fans on each unit via +5 from the molex but after I discovered that they are running in dual mode I abandoned that idea (the one miner I modified was getting way to hot with the fan supplied by +5). I cut off the male end of the Y adapters, removed the +5 wires from the connectors (since I'm not going to use them) and soldered the ground and +12 wires to the barrel connectors. A little heat shrink tubing and were off to the races.
If you want me to I can take some pics of the power adapters I made and post them.
I just read that some one modified bfgminer to support these things.... Going to try it later.
I really need a damn controller to get these things to run in single mode. Kinda not happy with them right now.
