I've been having a weird issue where one of my cubes randomly shuts "off"
I say off in quotes because it's still getting some power, but only 1 of the 2 power lights will be on (the 2 vertically stacked, the top stays on) and the fan continues to blow, but it pushes cold air and the device doesn't hash or respond to web requests. I can then un-plug and re-plug one of the 2 plugs (doesn't matter which) and it magically whirs to life again, for some random amount of time.

I have 2 cubes (and 1 BFL miner, no oc, total power should be < 700w) running of a Corsair AX860i, and it's always the same cube having the issue so I don't think it's a power issue. The fuse looks fine and I don't see anything wrong looking at the board.

Anyone else have this problem?
