Hint - that's exactly what the on switch does. 

Granted we're talking 5V with a max current of 1-2mA or somesuch, and not
440VAC.  It's no more dangerous than touching the red and black leads of
a battery holder[1] to a small lightbulb (such as used in a flashlight,
model car, etc.) or a LED to verify it works / you have polarity right.
Actually, given that it's limited to 1-2mA, it's probably SAFER than
said battery-holder (since most dry-cell batteries can supply 2A
current, albeit for a very short amount of time).

And to ensure the motherboard isn't the culprit, you can always connect
the PS_ON (green) wire (in the 20/24-pin connector)any GND pin (black
wire) with a short length of wire.
