So I should solder a ground wire to the aluminum frame? The walls of the case are made of plywood. I'm assuming the PSU was intended for use with a conductive case so that installing the barrel jack to the case would essentially just ground it.

You don't need to solder on there, just use a sheet metal screw with a star washer and a ring terminal. Yes, the board was probably meant to be mounted to a conductive surface (with standoffs.) However, if you're not mounting it to something conductive, you shouldn't have to worry. I'd still ground any conductive part of the case that you can touch though.

Hey guys, I have a question regarding grounding.

 

yesterday I received a power supply that I ordered for a PC build I am calling LugBox. The power supply in question is the Realan 250W12VDC-1106 which is a single PCB power supply that runs on 12 volts. Upon unpackaging the power supply I found that the 12 volt DC plug has a grounding wire. I'm assuming that this must be connected to the contact on one of the mounting holes, is this correct? Do I need to ground my other hardware as well?

My procrastination is the bane of my existence.

I make games and stuff in my spare time.

Not necessarily.

 

The ground wire (that goes to the wall) is generally connected to the metal case of the power supply. Just look inside any normal PSU.

 

Current doesn't flow through the ground of house wiring normally. If it does, then something is wrong. 

 

The ground is basically there to prevent the user from getting shocked when touching an electronic device. (So the outside of the device doesn't become "live" to 120V or 240 V depending on where you live.)

Alright, thank you.
