Are there any PC power supply wizards out there that could please help
me with the following query?

On a standard PC power supply what voltage levels does the motherboard
expect to see on the 'Power Supply Good' line (pin 1):

a) at initial turn on, before the +12V, +5V, -5V and -12V power rails
have stabilised?

b) when the power supply is operating correctly?

c) in a fault situation, assuming it has not a totally failed ;)
