'Grounded' leads on a DC plug?

[gulfcoastfella]

I've seen leads of internal power connectors labeled as 'ground'. Is that the right phrasology? To me, 'ground' always suggested AC current, whereas I thought a computer's internal power was all DC.

One of the reasons I'm asking is because I need to know how to hook up 12 volt molex connections in my computer to get 24 volts to power a pump...

Ground means an earth ground, relevant in both AC and DC applications. You are referring to neutral though, which would be the black wires.

Also, modern power supplies have a very small -12v rail, you will not be able to power a 24v pump from the -12v rail.
