Got to test some rails on a PSU.

Got my multimeter set to 20v, black in COM and red in voltage (not 10ADC)

Put my black probe into a black COM pin on my 24 pin atx plug which is plugged into the board.

Got to test the 3.3v/5v/12v.

Problem is:

There's quite a few 3.3/5/12 pins, so which ones do i need? -12v or +12v or +12v1?

Also, what is the best way to get the PSU at a Load state?

Help :D

Thanks,

Andy
