While I'm here... just ordered a second AM-V2 anyone have any thoughts on stacking vs not stacking and also opinions on PSU, I have a 1300 watt Platinum PSU from EVGA that looks like it could run two of these but BTC Gardens' stated specs call for a 750 W PSU for each.
(When I first plugged my V2 in I checked and it was drawing 634 W at the wall but I haven't checked to see how much this fluctuates while mining).
I've got 4x AM-V1 which I stack. And then 2x AM-V2 which I stack. The V2 board and casing is smaller than the V1 which makes stacking of V1 and V2 not easy-peasy.
I'm using the Dell P/S sold by minersource for all of them (2x per 1.2TH). I tape the two supplies together with aluminum tape (for ductwork) and then I safety wire them to the stack. I pop-rivet the miners to stack.
It requires one raspberry pi per 8 boards. Too bad, I was planning on running a floor-to-ceiling stack with one pi LOL.
With the Dells it is drawing 1450W at the wall per 1.2TH. These things run and run. I am constantly dicking with my other miners for one reason or another and these btcgarden always sit at a consistent 1240TH. Temperature monitoring and better power efficiency would be welcome though. I've got a blower fan behind the stack.
