It's far less likely that a switcher will fail to overvoltage. The
switching transistor(s) under stress, and most likely to fail, will just
cause the supply to die, as you have observed.
Still, I don't like entrusting the life of my K3 to one cheap resistor
in the feedback loop. That comes of
I haven't experienced that a switched PS causes overvoltage. They
usually just die!

Most likely due to overvoltage. Linear supplies are particularly
