Just got a new graphics card, now I have a new problem... - Hardware & Software

So, I just got an Nvidia GTX 660 Ti the other day. However, today I have a new problem which I think may be caused by the graphics card, but not directly. When playing games, I can hear a buzzing in my headset, and so can other people I'm talking to. But, when I'm not running a game, it's fine. I have concluded that it's something to do with my graphics card putting strain or something on my PSU. I can hear the buzzing coming from the PSU if I put my ear close. The other odd thing is that what I do in-game can effect the pitch of the buzz. To test it, I booted up the Far Cry 3 Map Editor. When I look at the ground, it's higher pitched. If I look somewhere else, it may be lower pitched. So, like I said before, I think it's something to do with my graphics card, but the actual noise is coming from the PSU. What should I try? I have an 800W PSU by the way. My 660 Ti says I should have a 500W power supply, so I'm not sure if the PSU is going bad, or if my new graphics card is just straining it too hard.

A friend once told me that when the GPU is getting too much power from the PSU it makes that squeaky noise

Which PSU do you have?

Is your PC grounded?

That is called crosstalk and occurs when circuits on your mobo aren't separated properly and high currents (GPU) interfere with other signals like for example your audio. Ground your case/PSU. Or if that fails, get a seperate cheap sound card.

[QUOTE=12voltsdc;38675066]Which PSU do you have?[/QUOTE] I got my PC in 2010 from CyberPower PC. It's one of their power supplies, specifically "800 Watts Power Supplies [-36] (* CyberPowerPC XF800S Performance ATX 2.0 Power - Quad SLI Ready)". I know it's kinda shady, and that's why I feel that it's just a crappy PSU and I need a new one. This is my first time changing the GPU in this computer since I've had it.

Just to be sure, I unplugged my PC from the power strip I had it plugged into originally and plugged it directly into the wall and it does the same thing.

Your PSU is the problem. You need to change that immediately regardless and avoid using your computer until you replace it. Assuming you're in the USA then get this: [url]http://www.newegg.com/Product/Product.aspx?Item=N82E16817371030[/url] [editline]Dec 2012[/editline] Just made a minor change if you're buying from United Kingdom: [url]http://www.ebuyer.com/413804-xfx-proseries-450w-power-supply-unit-core-edition-p1-450s-x2b9[/url]

Basically what's probably happening is the switching transistors on the GF660TI are backfeeding high frequencies into the PSU, which are then routed to everything else in the computer. While the PSU is designed to filter power from the AC source, it isn't designed to handle backfeed and doesn't filter HF coming back up the wires. While digital circuits are more resistant to this noise, analog circuits like sound chips that operate with very low voltage levels will pick this noise up easily and play it through the sound output. If you use the front panel audio connectors, try using the ones on the back of the computer.

That's actually a very detailed and logical explanation. The OP stated that he could hear buzzing coming from the PSU itself though so I assume it would be a serious issue related to the PSU itself. Would or wouldn't you advise the OP to still keep his PSU?

If the GPU is backfeeding switching frequency, it doesn't matter which PSU you use, it's still going to happen. On the other hand, the PSU could also be the culprit and not be filtering the DC properly. He never said what model his PSU was so we don't know if it's a crap unit or not.

[QUOTE=Darkmaster21;38689254]What would you recommend I try then? Should I get another PSU or not?[/QUOTE] Which one do you have now?

As stated in an earlier post: [QUOTE=Darkmaster21;38680595]I got my PC in 2010 from CyberPower PC. It's one of their power supplies, specifically "800 Watts Power Supplies [-36] (* CyberPowerPC XF800S Performance ATX 2.0 Power - Quad SLI Ready)".[/QUOTE]

[QUOTE=Darkmaster21;38689254]What would you recommend I try then? Should I get another PSU or not?[/QUOTE] Your PSU is garbage, I would get a new one regardless. If the buzzing still happens with the new PSU, you should RMA your video card since the power regulation circuit is clearly defective.

You kinda did good but before they ship it out I would get a refund and get this. [url]http://www.newegg.com/Product/Product.aspx?Item=N82E16817151102&Tpk=X850[/url] Fully modular and cheaper.

It's already been shipped. It's basically the same, except the one I got isn't fully modular, but it's still modular. I'm fine with what I got, but thanks though.

I'm gonna send the card back and get a refund and get another one that isn't factory overclocked.
