I turn off the computer only at night, is it worth turning off the surge protector so that the idle power supply in the system unit does not receive current at all? Or, on the contrary, is it better to keep it connected to the network all the time so as not to pull it once again? Preferably with reason.

It’s just that I already have a very ancient one, I changed the swollen capacitor in it twice, so I’m thinking how to extend its life.

There is no single answer.
Capacitors swell under load.
Disconnected electrolytes lose capacity and degrade.
Then it doesn't matter.

if you turn off the power at night, you will save a couple of kilowatts of electricity per year. It's all.
It is believed that electronics fails at the moment of turning on and off, therefore it is recommended not to turn off the computer at all, but even without turning off the computer from the outlet, you still de-energize the main units (processor, memory, HDD). Of course, a constantly turned on computer will lead to a large overspending of electricity and in real life, for any (turn off, do not turn off), your computer will become morally obsolete much earlier than it fails.

UPS - it is not recommended to turn off for a long time,
their batteries fail because of this (somewhere in a month of shutdown - noticeably worse).
conventional power supplies are completely de-energized.
they only have a circuit that provides inclusion.
Initially, everything was designed and calculated for this.
don't sweat it.
if the power supply even in the off state is very hot
, it means that it is poorly designed.
like this, turn it off.
when you leave the room for a long time - you need to turn it off.
little.
overheating, spark, fire.
PS:
it is not clear your attitude is scrupulous in this matter.
you'll get tired of it before it burns out.

It’s better to turn it off, otherwise we had a couple of times that instead of 220V they gave more and then it would definitely burn out. But my advice to you, do not try to extend its life, but rather change it right away, since the life of other devices depends on a stable voltage.
