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

I don't think that's the case. The PSU (VSP Megamax) doesn't have the voltage switch as it has active pfc. In fact, most PSUs can adjust the voltage accordingly.

Yea, i haven't seen a voltage switch on a PSU for at least 15 years, maybe even longer.

Plenty of cheap PSUs that don't have active PFC and require you to set the 110v/220v switch properly. That said, they are becoming rare enough that it isn't something that you would think to check these days...

You are right, now imagine that's the part that failed.

Also, if that ACTUALLY happened with PSUs just because the switch was in the wrong position, it would be a pretty big and easy-to-win lawsuit. A minor user error should not result in an electronic device catastrophically exploding.

I don't think it has active PFC, it's just a 240v only model.
