Hello,

So, went to turn my PC on, and it did nothing.
Had power to the extension that it is powered off of.
Turned power on/off, no change.
Flicked the switch on the back of the PSU a few times, no change.
Changed the IEC with the one powering my monitor, both IECs could power the monitor.
Switched the IECs back, no change. Then after flicking the switch on the PSU off and on, it worked.

So, just wondering - is it likely to be just a weird thing that happened, or a sign something will go wrong soon? And any way I can test the PSU to tell if it will fail soon?

Yeah, I know ground to MB signal, right now the PSU is working fine, I am just not sure why it wouldn't turn on before. I have a light on my MB that comes on when it is receiving power but off, so it wasn't the button not working / etc.

Just, it would be very inconvenient if my PSU died now, considering the amount of coursework I have, so want to try and prevent it from failing if possible.
