*Rob, possibly
you made the 110/240 switch wrong, but also
possible is that the PSU just wasn't ready to be turned on like
that. Electrolytic Capacitors (of which there are many in that
PSU) tend towards non-functionality the longer they sit unused.
Without those caps working right, the PSU will do pops, smokes,
and other alarming things. Then good luck fixing it.
I have to say, for all the talk of failing caps in power supplies
I've only ever seen one electrolytic cap fail *ever*, and that was
last week in a one-year-old graphics card that has hardly ever been
powered off...
