When you jumper (short) the green wire and a black wire, are you effectively bypassing and "turning the power switch on"?

If so, does that mean the green wire connects to the PSU power switch?

So, if I have the PSU "out of the computer" and "all PSU wires disconnected from everything" and I short (jumper) the green wire and a black wire in the 20 pin mobo connector, the PSU should come on unless it's dead....correct?

If true, this should be a simple test to determine if the PSU is dead or not. Advise me if I'm wrong please.
