Mini ATX PSU problem?

[the_irondave]

I recently traded a friend of mine for a power supply that I assume is some sort of mini version of a 20-pin ATX power supply. It even says ATX on it, but for some reason, there is a missing pin on the 20-pin supply. I looked up the pin orientation of the standard 20-pin connector, and it is missing the -5v pin (pin 18, I think). I was wondering if I could just take a -5v connection from the standard molex and wire it into the missing pin without a problem. Seems like it would work to me, does anyone see anything wrong with this idea?

It sounds like you have an SFX PSU which does indeed lack the -5v.

There is no -5v rail in a molex so..........your idea doesn't make a lto of sense.

Modern PC's don't need or use the -5V.
