Because I have a power supply that may be broken , but I don't have the motherboard to plug it into.
Should it power up if I short out pin8 to ground.
Currently it doesn't , but I don't want to waste time trying to find a fault if there is something else that is also required.

and even if it powers up, how do you know it's working right? do you have a motherboard/cpu/ram that you can possibly destroy just hanging around?
risking 100.00 in parts to check a 30.00 power supply that you have been told is bad is not cost efective
while there do exist ATX compatable power supply testers, HP uses non standard power supplies on many systems that thes testers will not work with

i cant answer if a power supply that you have been told is defective will power up because i have no idea what the problem within the supply is, and your last reply stating that i should somehow know this is rather short sighted on your part

again just because a power supply power up does not mean it's working correctly
since the DPS-600UB supply is from a z420 workstation, the supply has a builtin self test
also note that this supply is not a ATX standard pinout, it uses a HP custom power supply pinout
take the time to read the service manual hp provides for how to do this simple test
To test the power supply:
- Unplug the AC power.
- Remove the power supply.
- Plug in AC power and verify the following:
- If the green BIST LED on the rear of the workstation is illuminated and the fan is spinning, the power supply is functional.
- If the green BIST LED is not illuminated or the fan is not spinning, replace the power supply.
