PSU Spark

[Dr.ShaLaShaSka]

Recently I've been noticing that when I switch on my system after having it switched off and unplugged for a while it makes a loud-ish spark inside the PSU right behind the switch.
This doesn't happen every time I switch on, only when the PC is off for about a day and the PSU switch is off, but the system itself never has any trouble powering on and performs completely normally, should I be worried.

It's difficult to tell why and what is sparking without opening the PSU, but I would say it is a little worrying. Does that sparking happen only when you turn it on with the switch on the PSU?

What PSU is it and how old is it?

Your video doesn't play.

If there are indeed a spark (as in you can see it) then it's definitely not normal. You can however mistake a spark noise for relay actuation.

What PSU is that ?

The sparks happens only when I disconnect the PSU from the switch on it for a while (till the capacitors lose their charge), if I turn it off and on from the same switch immediately that does not happen, the PSU is a specail version from InWin that comes with their signature D frame 2.0 (SIII-1056 W) the system is 6 months old.
