You'll need some kind of load on it to get an accurate reading of its
output. Around 12 to 15 ohms, and able to disipate about 7 watts. I
don't know the supply requirements of those computers. But a couple volts
over spec is usually ok; if it wants an AC input, the computer must have
the remainder of the psu internal - its regulators should be able to
handle a little extra.
