PSU fired sparks after flipping the power switch.

[antoniokresic4.2002]

So I turned off me PC completely overnight beacuse I thought that there was gonna be a thunderstorm at the end it was just a peaceful night, today I come in my room , plug in the PSU cable in the PSU and I flip the power switch to ON, as I flipped it ON it fired a spark and i heard the usual spark noise. But my computer seems to be doing fine. What could have caused that? Please help me so it doesnt happen again. The power supply is a Seasonic M12II-520 EVO

This seems rather unusual, but if everything is working, then just keep an eye on things.

Is your PSU connected directly to a wall outlet, a power strip, or to an UPS?

Also, please don't start any more threads asking the same question. Thank you.

Its connected directly to the wall, I made 2 threads beacuse I thought that the first one got deleted. The web-site is buggy for me.
