Computer sometimes turns on then immediately off when resuming from sleep

I have a completed build with the following specs:
ASUS Z170-AR
Intel I5-6600K
ASUS Strix RX 480 8GB
Toshiba OCZ Trion 480 GB
Seasons 650 KM Active PFC F3 PSU

The computer runs fine, will never turn off spontaneously, and most of the time is able to resume from sleep and boot up just fine.

Occasionally, however, when resuming from sleep, the computer will turn on and then shut off immediately (within a second). The problem is always fixed by turning the PSU off from the back, waiting a few seconds, and then turning it back on. The computer will then boot up just fine.

This seems like a short circuit, but the problem is highly intermittent. Does anyone have any suggestions?

My specs are very similar with the GPU and PSU being slightly different. I have never experienced this issue, personally, and it sounds rather strange. I would have to say that your PSU is to blame. Perhaps the sudden jolt of energy needed to wake up your computer is a bit too much for your PSU to handle so the safety kicks in and shuts the PSU off. This would explain why the only way to fix it is by flipping the PSU on and off again to allow it to reset. I think the best thing to do is try out a new PSU and see how it goes. Everything in your build matches mine exactly besides your PSU and GPU and mine runs fine.
