ahh yes. the old game of “did the circuit trip because the PSU blew or did the PSU blow because of the circuit trip” Followed swiftly by “where the fuck did my spare PSU go” and then onto “Fuck me, what the shit happened to PC stores while my back was turned”

(I need to get my UPS on a separate circuit, about once a year we get a dirty feed that it regulates and then the RCD shits itself thinking it’s a spike)
