In my experience, when the electrolytics go, they go with a bang. Sometimes
accompanied by flames, but always by stink.
I used to volunteer at a facility that spruced up old computers for use by
the disadvantaged, and we had so many PSUs go bang that we finally set up a
dedicated "first power up" station, complete with a fire extinguisher and a
remote power switch.
Of course, it's always possible that the electrolytics have failed, but some
other component sacrificed itself to prevent the explosion. This would
almost always be something expensive; the Law of the Innate Perversity of
Inanimate Objects decrees that the thirty-dollar power transistor will
protect the ten-cent fuse, not the other way around.
