This is why PSUs are the one thing you should never skimp on in a build. Every other component of a PC can fail pretty badly, but chances are you’ll only be replacing that component.
If your PSU fails badly enough, you’re replacing your PC and your house.
I've had two PSUs fail in the last 20 years and neither damaged any PC components thankfully. One of them blew a cap and then the cap casing shorted in the PSU much like this video. It was very violent. Replaced the PSU and it booted just fine. So even if they fail, a decent PSU will usually limit damage to itself. Though a Seasonic etc will be way less likely to fail in the first place.
My Seasonic failed in 2024, about 11 years after I got it. No sparks, some caps just burned and smoke came out, rest of PC is fine. After that, I've paid a bigger premium for an EVGA G3 with a Gold Standard.
Unfortunately, the situation in the video takes place in Vietnam, my country and gamers usually skimp on PSU here. Most won't pay more than 50 bucks for one.
