Testing psu

The ADT 2018 PSU that I'm hoping to use for a new build, like most psu's, needs a connection to be made to switch the supply on.
I want to check it on the bench that it works ok before connecting it up.
It has an orange wire labled P.G. and a grey labled PS-ON.
I can't work out what P.G. stands for, and I'd guess that I need to short the PS-ON to ground to get the PSU to turn on.
Can someone enlighten me, before I turn it all to ashes.

Your link started me on the right trail.
Identifying the connector as a 20 pin molex led me to pinouts.ru, where I found the info.
The colour scheme is different, but the pin connections look the same, and it would seem that PS On needs to short to ground, and the PG lead lights a led indicator that all is OK re voltages.
Many thanks

You really need to use a proper power supply tester, to put some load on the supply - otherwise you'll get to know almost nothing worthwhile about it.

seems cheap enough.
