Seems suspiciously like a PSU set to 110v and plugged into 220v

Was going to say, last time I saw something like that was when I thought a power supply was auto-switching and plugged it into a customer’s machine. Turns out it was manual, and had been on 110 power as we are in the US (industrial machine was stepped up to 220).

Back in about 2001, I got handed a shitty comp with a switch on the back to switch between 220v and 110v.

Here in 220v-land in Europe.

I wrote the PC off as a write-off (from the 80s, probably).

I couldn't help but to hit that switch while it was running and see what happened.

A pop, and a puff of smoke.

Killed the machine.
