Also commonly caused by failure of the bridge rectifier. And it's rare
for the fuse to rupture - normally it just gets a nice coating of molten
metal on the inside.
But these failures are caused by skimping on those components in the
first place. If the makers have skimped on those components, what about
all the other components inside the PSU?
Cheap PSUs have more insidious failings - high ripple current, which you
can't see unless you use an oscilloscope, cheap capacitors and fans
which work initially but whose lifetime is very much reduced.
