But if you put it in the wrong way round does it just pop or would
something else bad happen? I.e. would trial and error with one spare

Be sure to plug the uncased supply into a hard-to-reach socket just
before putting it down on your lap...

Not usually a pop, more 'this power supply will self destruct in FIVE
seconds' c.f. James Bond.
