Getting shocked from back of pc

[CentR]

I know I need a ground but will my components get damaged?
I get shocked from I/O shield and metal back of case

[tacoshy]

depends on so many factors. where you touch the components. But in general grounding yourself is way overrated. besides grounding yourself doesnt mean to gorund on a heater or any metal part in the room but to ground yourself on the PC case to get the same electrical level of your PC.

Oh, so it uses you to ground itself, interesting.
Afaik I/O shield should be able to do that, it's got those metal thingies on the mobo side to draw static from components to the case. Tho there must be something wrong with the case design if it has to wait for you to discharge. Also, does it just discharge once in a while, or does it shocks continuously? As in the latter case there might actually be some kind of problem there.

In electrical engineering, ground or earth is the reference point in an electrical circuit from which voltages are measured, a common return path for electric current, or a direct physical connection to the earth.

Electrical circuits may be connected to ground (earth) for several reasons. Exposed metal parts of electrical equipment are connected to ground, so that failures of internal insulation will trigger protective mechanisms such as fuses or circuit breakers in the circuit to remove power from the device. This ensures that exposed parts can never have a dangerous voltage with respect to ground, which could cause an electric shock if a grounded person touched them. In electric power distribution systems, a protective earth (PE) conductor is an essential part of the safety provided by the earthing system.

Connection to ground also limits the build-up of static electricity when handling flammable products or electrostatic-sensitive devices. In some telegraph and power transmission circuits, the earth itself can be used as one conductor of the circuit, saving the cost of installing a separate return conductor (see single-wire earth return).

For measurement purposes, the Earth serves as a (reasonably) constant potential reference against which other potentials can be measured. An electrical ground system should have an appropriate current-carrying capability to serve as an adequate zero-voltage reference level. In electronic circuit theory, a "ground" is usually idealized as an infinite source or sink for charge, which can absorb an unlimited amount of current without changing its potential. Where a real ground connection has a significant resistance, the approximation of zero potential is no longer valid. Stray voltages or earth potential rise effects will occur, which may create noise in signals or if large enough will produce an electric shock hazard.

The use of the term ground (or earth) is so common in electrical and electronics applications that circuits in portable electronic devices such as cell phones and media players as well as circuits in vehicles may be spoken of as having a "ground" connection without any actual connection to the Earth, despite "common" being a more appropriate term for such a connection. This is usually a large conductor attached to one side of the power supply (such as the "ground plane" on a printed circuit board) which serves as the common return path for current from many different components in the circuit.

So do my components get damaged?

The case, IO shield and components are all tied together, holding the same charge. The danger would be having the side of and get a discharge of one of the circuitboards or electrical components on them, that could fry something.

More likely he has the case plugged into a non-grounded outlet.

I myself have been forced to use non-grounded outlets for most of my life. Never had components fail within an unreasonable lifespan.

If it is plugged into a grounded outlet, you have even less to worry about. You're the source and discharging yourself through a path designed to handle that. You might want to consider switching to more natural fabrics though, clotheswise.

If you are getting shocked from the motherboard i/o shield something is wrong, such as a metal tab on it touching the inside of the lan or usb port, make sure the shield is installed properly

[CentR]

well the PC is still working properly
so it's alright

You are correct I have a unsecure outlet

[_I_]

getting shocked is just you obtaining a common ground with the device
touching a ground is fine, data or power pins are not and may damage the device if you are not grounded first

if you are constantly getting shocked, every time you touch it within a few seconds
then its most likely a bad ground or outlet is not grounded properly

so is my system not damaged?

odds are its fine, just check that the outlet is grounded properly

Your power supply should have 3 prongs on it, and assuming your outlet is wired up right it will serve as your case's connection to ground. As long as you aren't touching any actual circuit board components everything should be fine. I get a static shock every once in a while when plugging in something in my front panel USB, because the metal housing of the USB slot is also connected to ground. The only danger is if you were touching the actual components inside the PC when you get a static shock, as static can be 10's of thousands of volts, which would be very very bad for a sensitive low voltage component. The case, IO shield, USB housing ect will all be grounded to your power supply which is grounded to earth through your house's earth ground, where it can safely discharge any static without hurting anything.

You aren't using an adapter to take 3 prongs from your power supply cable and make it into 2 prongs for an outlet with no ground or anything right?

Guys to be clear I did not get shocked when my PC is plugged into the wall it was when I plugged it on and moved it into another room without the PC having a ground

means I am safe
I am scared as I just purchased a Rtx 2060

The shock happened when the PC was unplugged from the wall? I'm thinking the static charge would have still discharged to the case where it would sit until you plugged it back into the wall, where it would go to ground.

Yea if it was broken from a shock you'd probably know it by now.

I'm pretty anal about this, I will touch the case with one hand (or be connected with the bracelet) and with the other hand ground to metal in my house. I know this is probably overkill but this stuff is expensive.

problem is i think the psu still had charge when i purchased it as my computer was tested by the store
so is it a discharge? i think it is
PS : computer store is 20 mins away so my computer still has some power stored i think.
i am using the pc that shocked me right now

Yea voltage is just a difference in potential. It wants to go from high potential to a place of low potential. Any charge in the PSU should be contained inside of the PSU and never make its way out. Any charge that's outside of the PSU will go to the case and be grounded.

Just to be clear, was this a single shock, maybe a little spark, only once and then it didn't do it again? Or are you getting bit by 120v or whatever is in your home where it will get you every time you touch it?

Like I said, if it was broken you would know because it probably would instantly stop working. Static shocks can be many thousands of volts, and the most your components use is either 12 or 24v i don't remember, so a shock to components would kill them right away.

Does your wall outlet have 2 or 3 prongs?
