PSU off switch

Hey,

I’m currently studying at uni and I’m home only during the weekend. Therefore I turn off my pc and. I do it with the backswitch from the psu.

Yesterday I accidently switched it slowly, (it took mby ~2 seconds) instead of swift click. And I heard little noise. From what I’ve browsed I know it was a small short and this switch is not supposed do be clicked slowly.

I will keep it in mind for the future. But I wanted to ask is there anything to be worried about this? PC seems to be working totally fine and my PSU is 4years old BeQuiet Straight Power 11 850w. Would love to hear some opinions since I have OCD and it’s another concern for me.

Nothing to be worried about, the noise was just a small arc inside the switch as the contacts got closer.

This also happens when you operate the switch normally, the arc just isn't sustained longer than a few milliseconds, and a good quality switch has arc resistant contacts that won't be damaged.

Everything is fine.

English is not my first language, so please excuse any confusion or misunderstandings on my end.

I like to edit my posts a lot.

Ideally you want to minimize arcing as much as possible, but once in a while is to be expected. It is fine. 

 

Are you saying though that you turn the PC off with the power supply while it's running? Or do you turn it off first, and then switch off the power supply?

Just a little arcing. Click the switch fast to prevent it. Nothing to worry about though.

No ofc no, I turn off pc normally, and like 15-20min later switch its psu off. And later the whole power strip.
