Power outage and power supply

I had a power outage and my PC stopped working. It just wouldn't fire up by
pushing the power button but the next day it fired up no problem. Do they
have some sort of thermal switch in modern power supplies?

Thanks

There is a thermal cutoff in any decent power supply but
that shouldn't have been invoked by a power outtage.
More likely your power was instable when it came back on, or
somehow the motherboard logic became locked. In such cases,
it can help to unplug the power supply from AC for a few
seconds, at least 10, then plug it back in.

It's possible that was a problem because they have it in a cupboard that is
getting quite hot. I'm going to add some fans to the case. Although it would
be a big coincidence that it happened at the same time.

That could have been it. Most likely they shut the power down for the night
at the switchboard, I've seen them do this before.

again after usually after a wait of 30 seconds or so
