Hello there!

I just made myself an account here on Tomshardware.co.uk.
Basicly, I bought the new version, so called XBOX 360 compatiable Razer Carcharias. The problem is that I get a small amount of static noise in my speakers in side the headset, however, that's a thing I could live with. They bigger and more nnoying problem is that on the actual microphone there's tons of static noise, which irritates the hell out of my friends that I am teamspeak 3 and mumble with. The headset has two 3.5 standard audio connectors that are lead to my ASUS Xonar DG, however, the headset also is powered by USB which is irronicly needed for this headset to work. So I have found out that the USB connections have static electricity in them and I have tried to connect to all of them on the back and even on the front and it is still making a lot of unbearable static noise. I've also read that you can ground your computer with copper wire. If I am doing it, where should the copper wire be connected? I've heard that it should be in the rear of the pc, quite near the PSU and be lead to something with metal. Is it completely safe to ground the pc from the back side of the case and to an element? Or is there any other ways of doing it? I've thought of another thing which is getting a AC powered USB hub that I have at home at let it be connected to the computer and then connect the USB hub with the USB cable from my Razer Carcharias headset? Would that work?



Much thanks from Sweden,
Artur.

Hi
Your power supply should be grounded anyway which will ground the entire case.
Check that your mains plug is 3 pin.
If the noise in your headphones is coming from the usb then your power supply filters are inefficient,if this is the case then the powered usb hub may work better but no guarantees.
I have heard of a number of people with this problem on carcharias headphones,Razer needs to include DC smoothing components inside the headphone.

Hey Makkem! Thanks for the advice. I believe then that it is my PSU, since it's an old Hiper Type-R 580W, that I've had for around 5-6 years. The sound is coming from the USB, so it's the an old PSU. My system is a Intel I7 2600k, 8GB ram and gtx 560ti. And another thing, the power switch on the PSU flickers a little bit, which could mean inefficent PSU, at least from my knowledge. Well thanks anyways Makkem, I really do appericate the help I've been given! Have a great evening! ^^

Also, when buying a new PSU, which brand would I go with? Since I don't want to buy a cheap brand. I am probably gonna go with a Corsair TX 650v2, is that a good choice for my system?

Sorry cant give you a straight answer on that as there is no information on how well smoothed the voltage lines are on PSUs.
It may or may not work.
Can you try your headphones on different computers and take note of their PSU makes.
If you are handy you could try soldering a capacitor across the 5v and ground lines to the usb socket you use.It would need to be about 1microfarad and at least 5V.This should smoothe the supply and remove the hiss.
