Greetings, ( Enermax pro87+ Power Supply Odd behavior )

Occasionally, when pressing the power button on the case the PC won't show that it is beginning to power up.
The power light might come on for a split second but then go off.

Switching off the PS and then back on usually cures it. This has been going on for more than a year but only happens about once a month on average.

However,
Tonight it happened again, I let it stay off without switching the PS on and off,
and I thought to put a power supply test on it, but I needed to do something else first before testing.

Then on it's own -
10 minutes or more later, it just booted up without me once again hitting the power button.

I'd appreciate any thoughts on this.

Thank you!

Steve

When power supplies begin to fail, they can exhibit all manner of faults.  When a PS shuts down for whatever reason and the power is not removed, the fault may eventually clear itself and attempt to restart.  This could be a hazard as if left on and unattended, the PS could attempt a restart and fail, spectacularly, as in starting a fire within the unit.  Fuses and breakers should remove power if current ratings exceed the device limits.

Thank you.
I have a new spare and I'll replace this one asap.

 

EDIT: Replacement done.
