APW++-12-1600 Bitmain PSU not outputting any power

[KEBKR]

My PSU has stopped outputting any power. The fan powers up but there’s no power output happening.  Anyone have any experience with this or is it just dead?

Often when the APW3++ psus die, the fans will still spin up. I would still consider them dead if they aren't outputting any power, though.

When one of mine stopped supplying power (think it went into protection mode) I had to leave it unplugged for nearly 10 minutes before it would supply power again. A quick unplug did nothing, fans would spin up but no power.

If you have voltage meter then check all 6 pins cable the output must be 12v if all cable gives you a correct voltage then the problem is your miner and not your PSU but you must reboot the miner first and let it run for 10-20 minutes for power cycle.

possible that semiconductor or mosfet exploded. we had that problem happening in one of my company farms. maybe because of overheating..we dont know the exact cause.

To clarify what BitMaxz said, the APW++ supplies need a rest with power off for 5 min or more before they will restart after shutdown from overload/heat.
