Slight electrical current in psu

post #1 of 9
Thread Starter 
All right I installed my new Antec TruePower 2.0 480W psu about 2 weeks ago.
Everything is going fine except for this little detail that's bothering me.
Sometimes (not all the time) when I touch the screws going through my psu I feel a light current flowing through my fingers. It's not that important a current but it's enough to make you want to take your hand off.
The thing is I didn't use the power cord that comes with the psu (and that has a 3rd outlet for ground) because I don't have a grounding installation in my house. Instead I used a normal power cord with only two outlets.
My question: Can this be detrimental to my machine/psu ? I mean will it be likely to damage some of my components ?

I would use a volt meter and get a reading on it, but I am curious. No matter what if there is current it should be replaced.

Is there a little screw right below the first 2 prong outlet? If so, there should be a metal tab that you are suposed to have screwed into the outlet. That screw is the ground wire. But you should not have your PSU ungrounded, having it ungrounded may lead to a sort of bridged ESD (if you tough your PSU and a component at the same time).

BFRD, you mean check the readings for possible fluctuations ?

Some_Idiot2, concerning the little screw right below the first 2 prong outlet... you mean I should look on the original power cable that came with the psu or the power cable I'm currently using ?
I know it shouldn't be ungrounded but it's like I have no choice. What am I going to connect it to ?
Hmmm all right so you're also saying I should not touch both my psu and back of the case at the same time ?

Sorry for the crappy paint pic, but I just reformated.

All right, if I understand correctly from the first black and white pic you posted... I should take off/cut off the metal part colored in red (see attached pic) and connect my power cord via a wire to the screw in my wall outlet ?
Can I connect it to the wall outlet without cutting the metal part ?
Sorry for the silly questions but I'm trying to make certain I'm doing the right thing here.

You should use an adapter that already has the wire attached.

Previously I was simply suggesting that you measure the amount of current that you are feeling.

All right, I'm going to find an adapter like the one Some_Idiot2 pointed out in the colored picture. I will then connect the attached wire to my wall outlet screw.
Thanks guys !

No you souldn't cut that off. Go out and get an adaptor and screw the metal tab or wire into the outlet. That way you'll be grounded.
