A case with perfect grounding

Octopuss · Sep 9, 2010, 10:55 AM

Some people say grounding is still a big problem (in some cases) even with higher grade more expensive cases. I have Auzentech X-fi forte I gave up on using because of constant sound problems even with new drivers. One guy suggested it MIGHT be grounding problem and according to his tests, some current can be measured on almost every case out there, which possibly causes problems.
So my question is, are you aware of any case in under say $200 range which is perfect in this way?

I really wouldn't have that as my main requirement for looking for a case, its a moot point and even if most cases have some kind of current going through them whiich I can't comment on, its obviously not that big of an issue as there would be a lot more talk about it.

try a high end coolmaster or a NZXT case, both are great choices

Papahyooie · Sep 9, 2010, 11:22 AM

Ground the case to the screw on a wall outlet or something like that with a wire.

Bo$$ · Sep 9, 2010, 12:00 PM

i dont think it is ground although the OP mentioned it, maybe it is interference in the case caused by the computer components inside it.

I heard about this method but I do not like it very much. Extra cables/wires suck. Also, howwould I attach it to the case to make sure the contact is good? (or where of course)

slyfox2151 · Sep 9, 2010, 12:19 PM

touch the inside of the case and see if that fixs the audio... if it dosnt then its not likely a grounding issue....

Good idea. I will try it, thanks

Beertintedgoggles · Sep 9, 2010, 12:30 PM

If there is current going through your case to ground, then there is an issue with your components leaking current onto the ground plane rather than the return lines (the black wires). Not an issue with the case at all. In fact, even a well grounded case would still have current running through it in the above instance because it's doing what it's supposed to.

mudkip · Sep 9, 2010, 12:38 PM

touch the inside of the case with one hand while placing the other hand on one breast. if that doesn't fix the audio problem your soundcard is possible gay.

Do you have a link to the actual comments "one guy" made?

I am interested in what sort of currents he found; DC? or AC?, if AC what frequency? What amperage are these currents? How is he determining these currents exist?

Chassis grounding exists for one purpose; to direct transient voltages to earth in order to protect personnel from electrical shock.

Wow my soundcard was playing up and I just tried this and it didnt work, whod'a thought it I thought it was faulty and all this time it was gay!!!

Oh and sigged

My english is not good enough to translate that and besides, I have like zero knowledge about electricity, so sorry, can't.

Use the thanks button now and then you have been here over a year and not given one, its just polite

Octopuss · Sep 9, 2010, 02:53 PM

What does a button have to do with my question? I have no idea what are you talking about.

Absolutely nothing, only 9 people have responded to you so it was just a suggestion

Bye

He is just stating, that if you appreciate the help people are giving, use the "Thanks" button once in a while. We appreciate being thanked sometimes.

the best way to check if your case is grounded is...

take the plug out pf the PSU
take a LED, attach long wires to it.
then touch the positive wire to the top of the cmos battery.
take the other wire and touch it anywhere on the case, or the earthing wire of the PSU.

if the led glows, everything is well grounded.

this can be tested with a multimeter too, but how many peoplw have multimeters?

Octopuss · Sep 9, 2010, 03:12 PM

That's very good idea too. Will give it a try when I have some time for experimenting. Cheers.

de.das.dude · Sep 9, 2010, 03:32 PM

cheers

W1zzard · Sep 9, 2010, 03:34 PM

on every single case that i've seen the metal frame is connected to the metal frame of the psu which is connected to ground on the power cable.

you screw your card to the metal frame of the case, so it is grounded.

get a multimeter, set it to measure resistance, pick two spots that you expect to be ground, put probes there, resistance should be <1 ohm

de.das.dude · Sep 9, 2010, 03:35 PM

there is a connectivity checking mode on multimeters that can be used.

in this mode, a true connection gives a beep. also the resistance is shown
