Sure,

Computer power supplies (types AT & ATX) both output 5 volts (yellow wire) &
12 volts (red wire), just don't exceed the wattage output which is probably
on the power supply label.

For instance, if the device you are powering needs 5 amps at 12 volts, your
power supply needs to be capable of at least 70 watts (dc voltage x dc
amperage = dc watts)

AT power supplies are the easiest since they are generally not reliant on
the motherboard and have a physical switch. ATX power supplies generally
have a purple wire that I think you have to tie to the yellow - could be all
wrong on that, it's been a couple years but that's the general idea.

Would like a computer power supply for other purposes without a
motherboard connected. Either AT or ATX? Has anyone done this? If so,
how?
Any help?
