Since I am not very electrically minded at all, are there some instructions or tutorial somewhere that I could follow to add this switch to the PSU using the green/yellow wires?
Thank you so much for any info you can provide!
To add switch to it:
Got to hardware store and buy a small simple push or twist single pole switch with wires on it.
From the same aisle in the store get some small electrical wire twist caps for 18ga wire.
Go home.
Remove the jumper from the green/white wire pair.
In the middle of it cut the wire loop on the jumper.
Carefully strip back about 1/2" of the insulation on the 2 wires.
Twist one wire from the switch and one from the jumper together. Twist clockwise.
Twist on of the small electrical wire caps. Do same for the remaining switch and jumper wires.
Done.
