Pls read our above post again. Our plan is to empty our stock on A2 Terminators now and only make Farmboys in the future. Terminators are too heavy and too expensive to support. Everytime we receive a PSU maintainence email, we will scratch our head, J! Better leave PSU outside in the future. Lot of computer store and internet sites to buy them cheap and locally. Used power supply tends to be very cheap and they are easy to obtain used! All in all, it is you call.
Aaah, thanks for clarifying. I'm checking with my miner host to confirm, but I was originally told that my 110MH model was drawing 830W. If the 1050W figure is accurate though (and I assume you'd know this), the numbers would shake out to...
Terminators:830W => 88MH => 9.43W/MH
Farm Boys:600W => 60MH => 10W/MH
...which still makes the Terminators more efficient, though barely (and at best, the same). I suppose that's not taking into account the 10% power variance, which I'm hoping you can clarify, actually. Aren't all the ASICs in the same location from board to board? And if not, wouldn't it be smart to figure out what the optimal location is and then just stick with that so that there isn't a 10% variance?
Another factor is the density of the machine. At 4Us, Terminators already weren't very small or dense, but it seems the Farm Boys would be almost half as dense.
Terminators:110MH/4Us = 27.5MH/U
Farm Boys:60MH/4Us = 15MH/U
It sounds like this is intentional, but I'm not sure you realize this will very likely make hosting more expensive.
I welcome your feedback.
