Gone are the days of PSU exploding left and right. They normally just shut down themselves if something bad happens.
I don't know about the vendors but I actually enjoyed the days of hardware malfunctioning in a hazard way, melting CPUs, etc 😀
I think... even the cheap PSUs these days, are pretty safe to operate. Well unless somebody uses HARP or other electro-magnetic weapon ;-)
P.S. Just keep one for spares.
