Look at this instructable.  On most power supplies there is a brown wire called the sense wire.  If this is not connected the power supply won't turn on.

Also some of the power supplies don't have good regulation unless they are powering something so if you measure the 5 and 12 volt lines they won't be accurate unless you put a load on them.

 with a little messing around i found that touching the blue and green wires together will turn the power on.
