What PC components will give you a electric shock if you touch them while it is running?(not static shock)

[Newblesse Obblige]

I want to know this as I might touch something that I shouldn't touch while I test my newly bought and running components.

[kelvinhall05]

Don't touch any power delivery stuff, but why would you be touching a computer while it's on?

[PeachGr]

Except PSU, the others are running on DC 12v.

That means you won't die but you will feel a shock if you try enough. ALSO DON'T TRY IT!

you should never ever ever touch the insides of a running pc. there are fans running that can cut your fingers if you are unlucky and some components could indeed shock you, only touch the insides when the computer is off and the switch on the power supply is switched off so that no power is getting through to the components you are touching, and always make sure you are grounded to stop ESD from damaging any components you touch, that can happen even if there is no power going to the components.

When I'm doing a test if my newly bought components like CPU, Cooler, RAM, Motherboard and Graphics card, are working properly. I am a rascal and clumsy so I might just something that I shouldn't

Why would you be testing shit by touching it in the first place?

Things can happen to me as I touch things unconsciously which isn't the case for the rest of you.

As long as you don't touch any bare wires I think your OK

[Moonzy]

anything inside the computer SHOULDNT shock you, as it should be grounded so the voltage relative to ground should'nt be too high

 

any voltage past the PSU is safe (you only get 24V max from bridging -12v and 12v with your body, even then the current is very limited)

the PSU casing or other bare metal parts are safe to touch. people designing a computer dont want it to be a death trap.

 

that said, you shouldnt touch anything anyways, the risk of you dying is near 0 but the things you touch might die, as you might bridge things with a sweaty finger or smth.

 

if you feel a tingly shock when you run your finger across your computer, it most often means it's not grounded and the surge protector feature of your PSU wont work.

[Lord Bloobus]

Don't stick anything metal in the PSU and you'll be fine as long as everything is installed correctly.

Isn't it counter intuitive, at a fundamental level, to put your hands inside a powered electrical device?

 

Especially, when it is one with as many "moving parts" (for want of a better expression) as a desktop computer. 

 

If it was me I would turn everything off, then unplug everything, then wait a good 10 minutes, and even then I'd be as careful as possible. 

 

I expect this might be unnecessary, but it's how I would react regardless.

I get the feeling you were the kid going after the electrical outlet with a fork... 

 

Thank God your parents kept an eye on you.

But I used a disposable fork so close enough. lmao

maybe. regardless a lot of people do this, maybe even "unconsciously".

 

often it's to check fans or whatever. yes you shouldn't do it, a lot of people who build PCs however do this.

 

that said I think one should really just touch plastic parts if possible tho.

pro tip: if you press the power button for 10 seconds after you unplugged the power cable the components inside discharge  so no need to wait 10 or whatever minutes.

 

(you can still get electrostatic discharge, but that's something different)

 

Also do not work on a PC in a room with carpet (bad idea)

It's just my cautious nature.

 

I've always waited a little while thinking there could still be some residual power left in the components for a short while afterwards. 

 

Glad to hear it's safe to do stuff sooner than that.

I'd just be so paranoid messing about with something that was switched on and fully powered up.
