Case grounding

Lets get a thread going about grounding our cases?

Turns out, that the PSU case is grounded, so the idea is that the whole case plus all the electronics connected should be grounded too. Not quite, since they started painting those cases they are basically NOT GROUNDED. Why is that? Are they stupid or something?

>grounding
Meh, been running all my computers ungrounded for the last 15 years.
I just avoid touching the case and the radiator at the same time.

Because all of the dangerous voltage are contained inside the PSU case.
So, theoretically if something short you're already protected.

Protip, your car is painted too, but the parts are still grounded because screws cut through the paint.

what an idiot

yes that's the idea, but the screw cuts only on the PSU, the hole is larger on the case /doesn't cut in/

i have tested it with a multimeter, the resistance was very high and charge was building everywhere

this is actually a legit issue

your argument is invalid

Its fine. The case doesnt need to be grounded. Plus it grounds through your motherboard, cd drives, pcie cards etc.

that sounds a little oversimplified

the powdercoat they use isn't ideal and the bonding will go up, but it should still be conductive enough that the voltage drop is minimal

My entire house isn't even grounded. None of my sockets have the extra pin. Nothing ever happened though. Starting to think grounding is a meme.

Grounding a case will improve sound quality.

It will remove all the buzzing and artificial noise

I have shag carpet in my room.
Piece of cardboard underneath the case did wonders.

If grounding is a meme then jam a fork into the outlet

exactly the opposite

grounding has fuck all to do with that

It does help to get rid of the 50/60hz hum in most cases.

The case is grounded, through the mainboard standoffs, connected to the mainboard, connected to the PSU ground.

If the painting gets in the way of the grounding then it would get in the way of the current if it came into contact with live power as well.

the big pin is a ground pin you blithering idiots

Not in most cases (Ground loop)

Case being grounded has more to do with EMI shielding then electrical safety.

Not putting it on the floor would do even more wonders, especially for dust accumulation.

Wait...
ATX black wires are ground
Ground on the mobo connects to all the pads around the screwholes
screw goes into standoff
standoff goes into case metal
Shouldn't that ground the case?

If it still doesn't, try scraping a little paint off around the screwholes for the PSU.

All voltafe coming out of the psu comes under the selv section of voltage so no one realy gives a fuck you might get a quick tingle if you touch the case while also touching an earthed point its not going to harm you

>Case being grounded has more to do with EMI shielding then electrical safety
This is probably the dumbest thing I have read on Sup Forums all week.

DC ground is different to AC ground.
You don't really want them to share a common ground. Bad things could happen.

Mines on the ground as well, with a slab of corrugated plastic cut to be essentially invisible under it. As long as you have filters it's fine. I don't get much dust, and I smoke stuff up there sometimes. Also have a cat that likes to rub on the intake when the computer is on.

>ince they started painting those cases they are basically NOT GROUNDED
so did you actually measure and check that, or did you pull that out of your ass?
