My GPU makes my PSU coil whine...

[Pepi93]

After some testing I have come to the conclusion that my 980ti is causing my PSU to coil whine...constantly...it's not a high pitched whine but a low buzzing...

I don't recall hearing any coil whine with my 970 so I unplugged my 980ti and used onboard graphics and voila, no coil whine.

I'm pretty sure this is a "live with it type of scenario" but I thought I'd ask just in case someone has come up with ideas other than the OCCT burn test.

I have also tried to enable Vsync in NVIDIA 3D settings to be on constantly and this did not help.

My GPU is not overclocked but even if I run my OC settings, the whine is there.

I've already addressed the issue with EVGA but their reply was that high end GPU's could cause this and getting a replacement PSU will most likely not fix it.

Thanks in advance

What type, power, and how old is the power supply?

 

[Pepi93]

EVGA 1000W Platinum PSU....few months old

 

[EarthDog]

Does changing the voltage and frequency of the card help?

1Kw platinum?? I hope you planned on 2+ 980Tis...

 

[Pepi93]

I bought the PSU bc it was a steal (it was a one day sale or some such on newegg). A 750W G2 at regular price was basically around what I paid...

Please give me some tips on changing voltage/frequency. Other than overclocking, not sure what to do exactly.

Thanks.

 

[EarthDog]

No tips.. just change/overclock it...

 

[JrClocker]

I would try basic stuff like making sure the GPU is properly seated, and all power cables coming from the power supply are fully seated.

Next, I'd try a different surge protector that the power supply is plugged into.

So I think I may have found a solution...

Seems the coil whine is triggered by using "Adaptive Power Mode" in NVIDIA 3D Settings. I have it set to "Performance Power Mode" and the whine is gone.

So now I have to weigh the options of whine vs warmer idle GPU temps

 

[EarthDog]

Weigh the options? What is the idle temp?

 

[Mr.Scott]

Weigh the options? What is the idle temp?

Doesn't matter. What do you do at idle except look at your idle temp?
It's a no brainer.

 

[EarthDog]

Just making sure it wasn't out of line.

 

[Pepi93]

Seems I can't spell...

Yeah that's exactly what I do, sit staring at the temps

It's been stupid hot all summer as I'm sure it has for most of you so every extra degree counts right?

 

[EarthDog]

Stupid hot indeed. But, no temp worries here.

I have to honest and say that I don't look much anymore after my overclock is set and tested. I don't push the overclock, so my cooling isn't pushed... so if we get stupid hot, I still don't have to worry. I find I enjoy my computer more when I'm not sweating those details as I used to.

Myself I found that I don't even really need the OC to maintain 60fps on all my games. I did set the core to 1500 but I'll leave the mem at stock...

How loud is the coil whine, Did EVGA say they would RMA the GPU?

 

[Pepi93]

PSU EVGA
GPU Gigabyte

EVGA would RMA the PSU no problem but would that make a difference? Doubt it.

The sound was a low pitch buzzing which I originally mistook for what a HDD spinner constantly spinning would sound like.

 

[wingman99]

The PSU would not help if it is not making the Buzzing sound. What does Gigabyte say about the buzzing that sounds horrible.

I don't understand?

The PSU is buzzing, not the GPU

 

[wingman99]

EVGA PSU buzzing that would be rare. How did you separate the sound so you know it's coming from the PSU?
