Short cracking noise when flipping the switch off

[kvrier]

Hi,
this is a story why you should get enough sleep before messing with hardware.

PSU: Kolink Continuum 1200 W Platinium 80+

I disassembled my PC for cleaning, after putting it back I forgot to connect 10 pin to the PSU. (as shown in the picture).

In other words, 18 pin alone was connected to the PSU, and 20+4 pins to the motherboard. I haven't noticed that and obviously PC didn't turn on.

I began inspecting hardware and I've done the paper clip test putting it in 4th pin and 5th pin. PSU made short cracking noise. I've noticed my mistake and put 10 pin cable back again.

Computer works normally, fans are spinning, everything looks fine except that PSU sometimes makes short cracking noise when I flip off the switch. It doesn't make that sound when I turn it on. I can't smell smoke or see any sparks.

Should I be concerned? If yes, what should I do next?

Hi guys, thanks for quick replies. I've been busy reinstalling OS on my laptop and that's the first time I could have a glance at the forum.

When you say 4th and 5th pin, you mean on 20+4 connector, on the side closest to the connector clip (pins 16 & 17)?

Exactly, just following what I've found on the web. It's good to hear everything is alright, fighting with customer service for a replacement is the last thing I need right now.

When both are high results are spectacular:

Wow. That's more than spectacular. I can't get my head around how electricity finds the shortest way between contacts creating an arch and not just a straight line.

(wouldn't be any wonder if Kolink used some cheaper switches)

Is Kolink less reliable manufacturer than others? I'm green in these stuff, that's my very first 1000W+ setup.
