Please help me out! Antec 300 front panel.

post #1 of 7
Thread Starter 
I have a case: Antec 300
My motherboard is: ASRock AM3 processors AMD 770-140W 4DDR3/ATI CrossFireX motherboard M3A770DE

(Beware im a computer noob sorry ><)

Basically, there is this problem with the grounding of Antec 300 which can be found here...

http://forums.bit-tech.net/showthread.php?t=208880


I have a question kind of regarding this problem.....

It isn't regarding the grounding loop, because when i opened my case there was no cable connecting the audio to my usb slots.

But when i plug my headphones into the audio jack, everything sounds as if i only plugged my headphones half in but its actually all the way in. This basically renders my front panel audio useless which really bugs me.... so i took apart everything and tried to fix the problem.

My problem is... when you touch the metals of the audio and the usb slot it makes a noise, just like when you did your 'quick test' . But when they don't touch, there is no noise. Well....when im playing a song regularly, it sounds all jacked up (not crackles but a distorted version of the song). When the metals touch, it plays the song normally! without any thing. When they don't touch my song gets all screwy again....

Does anyone know the fix to this problem? Please help me out! I hate having to go all the way back there to plug in my headphones.

hmmm thats weird. When did you purchase your 300? Cuz i got mine in late 2009 and it has that front audio port static problem, which I recently fixed by cutting the ground wire from the USB port to the audio port.

have you tried connecting a speaker to your front audio port? but then again, if your headphones sound alright when connected to the rear audio port then that means your headphones aren't broken.

what do you mean by when the metals touch? You said there wasn't any ground wires connecting from the USB port to the audio port, but you said when metals touch. Do you mean when you touch it with your finger or do you mean when both USB and audio port's metal in contact?

If you just recently purchased the case, you could probably contact Antec and ask for a replacement for your faulty USB/Audio port. But wait a bit for people who knows about this problem or who came across the same problem.

Idk if it will help, but you should show us some pictures of the USB/Audio interior casing.

Thanks for the reply.

The pictures are all in the posted link in the opening post. But ill repost what i mean when the metals touch here.


Thats when they touch


Thats when they don't touch.



Basically, when i plug in my headphones to the back part. It sounds great but theres this small interference that just doesn't go away. Similar interference can be heard when i plug my headphones to the front and the metals are touching (when playing music with metals touching, it plays normally). I'm not sure if this has anything to do with the problem but im trying to give as much info as possible.

Any help would be appreciated!

hmmm so it needs to be in contact with the USB port's ground to fix the sound....well that green wire looks like it's been cut which I think is the ground wire. Normally it's connected to the Audio port, but did you cut it or you found it like that? If you found it like that then you will see some soldering to the Audio port with no wire.

Try to solder the green wire to the Audio port. And if it's too small to solder to the Audio port then try to extend it with a 24gauge stranded wire(doesn't have to be 24g std as long as its not too thick that you have a hard time closing the Audio/USB plastic case). And if you don't have any soldering iron then just wrap the stripped ground wire around the metal housing of your Audio port and hot glue it or use electrical tape.
