Anyone use this powersupply for powering projects or as a bench supply? I found one in the trash and its supposed to deliver 19.5V but the volt meter shows 4.5Vish volts instead. I suspect the PSU is indeed broken or that it won''t supply the full voltage unless the PC and the PSU have some sort of handshake transaction. Anyone know? because this would make a great compact portable supply for powering motor power rails on many of my boards.
