What kills me is that the Jupiter boards had the mounting point for another power connector that no one needed. If they would have left that on the Neptune boards, there would significantly less complaints and returns. It was a pain soldering another power connector on the Neptune boards. But it made my ax1200i & ax1500i happy with 2 cables to each cube and no overheated wires or over-current problems...
What happens when you put a Y cable on your 5th miner and connect your 12 and 1500 to it? I would think both PSUs would balance out.
I wouldn't power one cube with 2 different PSUs or 2 in general...
I have 3 cubes on the 1500 (6 cables) and 2 cubes on the 1200 (4 cables)...there is room for up to 8 cables on each PSU
