My VS3100/M30 PSU does say 100-120/220-240 volts on the sticker attached
it.  There is however no voltage selector switch, and I'm looking at the
PCB, and there's no connector for 220V .. I have often seen PSU's that
have 2 pins on the board, which are labelled 120V and 220V, and there is
a wire that you simply move from the 120V pin, to the 220V pin, but
there is nothing on this PSU for that, it is most likely auto sensing.
