Do you switch your PSU on/off via the switch at the back every time you use your PC?

Do you switch your PSU on/off via the switch at the back every time you use your PC?
Might be a bit of a duh question for some, I suppose? But do you?

For some reason I was thinking of something that Alev Tav said to me many years back when I called them about some problems I was facing regarding possible PSU failure on a Verudium PSU (yeah, remember those?), and I brought up to them that, when I switch the PSU on or off via the switch at the back of the PSU there’d be this electrical ”bzzzt” noise ... and the guy told me - quite matter-of-factly - that I shouldn’t be switching on / off via this switch in the first place, just leave it on and switch on / off at the power socket.

Does anyone here actually believe in that?

Usually that switch will be remained ON all the time.

Unless want to do CMOS reset or remove the whole casing.

That puny switch actually has quite low cycling rating compared to other switches that you see.

Plus the bzzzt that you're hearing is arcing due to the low spring force and consequently low switch-closing speed.

Motherboard still need tickle charges to maintain the components. Always turn off your PC by shutdown in the windows. Never off the power completely.

When i need to replace any parts or disassemble, i will off the switch and remove the powercord. Most people dont do that and it makes me cringe.

I turn it on/off whenever I like, and never had issue before.

My last psu served me good for 8 years and I still could sell it off for $30 on Carousell.

I will off/on the PSU switch, then off the main supply switch when I am doing the follow:

-Reset CMOS
-Changing/upgrading of components.
-Bootloop restart of computer when overclocking goes haywire
-Extended holiday and I turn off the main power supply.

Other than that it stay on.

Motherboard components. Hardware can simply "died off" when when the PC is off from a long period of time. Same thing with phone or other electronic stuff. I believe technology hasnt changed much that we dont need to.
