[SOLVED] My PSU sparked when first turning on the switch at the back!?

[rbissett1999]

I built my second custom pc.
Once plugged into the wall I then turned it on at the wall then the back of the power supply. When I hit the switch on the power supply it sparked with a loud noise. My pc booted fine and seems to be running fine, I am currently installing games on it right now. After seeing a previous post about how this could be a faulty PSU I am now worried that it may damage other components. I did try it again multiple times and it did not do it again. Some re-assurance or advice is appreciated

I happened to notice the spark after viewing back this video

It's called in-rush current. You have a completely discharged bulk capacitor that needs to be fully charged in under a second.

So this is normal?
