Using PC without grounding

[divyu01]

Actually i live in a very old rented house and now i am thinking of a buying a pc but i heard that grounding is necessary for PC then I asked a electrician whether my house has grounding or not he said no then i thought my house has 5 holes outlet and it should have grounding, plz tell me if i am right or electrician and another thing i have bought a inverter ac and a new fridge and its been like 1 year that i have been using this in my house and when i touch them i dont get a shock so if a run a pc then it should also be fine right ?

I believe the word @divyu01 is looking for is grounding (as in electrical outlets with ground ports). Might want to edit the post to make this a little more clear, but I was able to understand what they meant.

no my house doesnt have ground wire ethier i have no problem at all

A lot of our PCs at my job aren't grounded. It works fine, just be sure to have decent electricity setup in your home.

im no electrician, so take what i say with a grain of salt

 

im not sure about other countries, but UK plugs have their neutral line earthed, so technically if you connect to L and N (which u definitely need for electricity), then you're technically earthed.

the earth pin is just an extra layer of safety in case something is wrong with neutral

i want to use a pc with these specs without grounding it - i3 9100f 1650 super 4gb and 8gb ram and also to mention here this house has old wiring and no grounding and all other appliances like laptop inverter ac and fridge work and its been 1 year plz confirm cuz its a matter of risk and money btw i live in india and my house 5 holes outlet plug

it seems you dont know what ground is.ground is a fail safe.all metal that is not circuit board is grounded in a psu in case live wire touched the metal body breaker pops and dont cause electrocution for person

There is nothing wrong with using the term "earthing".  "Grounding" is what's typically used in the U.S.  "Earthing" is what's used abroad.  Example:  In the U.S., your plug has a ground pin.  In the U.K., your plug has an "earth pin".

 

It comes from "Earth grounding".

 

Anyway... The lack of ground will work... until it doesn't.  It's there for a reason.  Like a seat belt.  It works fine now, but when it's needed and it's not there, the results can be catastrophic or deadly.

 

If you have a short, without a ground, your chassis can become energized.  If you have an electrical surge, the MOV can't send the extra voltage to ground to protect your PC.

 

And on and on.....

Earthing is a better term than grounding because "ground" in electrical systems doesn't always refer to "connected to the earth" whereas "earth" does.

 

The earth pin in a power outlet connects to the chassis of the power supply (and the computer case for that matter) so that if at any point a live voltage is applied to the chassis, the earth pin shorts it to earth, meaning there's no voltage between earth and the case, which means you don't get electrocuted upon touching the case. 

 

As far as short circuits are concerned, earth has nothing to do with that. When a short takes place, excessive current is drawn from the outlet, which will open the breaker and kill the power regardless of the earthing. 

 

In non-mobile appliances with no moving parts, like computer power supply it's unlikely that a live wire ever touches the chassis, meaning having a computer on a non-earthed outlet is pretty low risk.

Is an MOV not just wired up between the power wires rather than to the chassis?

I've seen it in some applications, but not PSUs.  I believe if you want to meet IEC 60950-1 and newer requirements, it's neutral to ground.

better I shift to another place where earthing is provided but this lockdown prevents me from doing this I will have to wait for years I think
