FPS and noise

[Cedric Germain]

Hi everybody,

Since a week, I have a new PC

Coolermaster - CM Storm Scout 2
Intel Core i7-3770K, 4x 3.50GHz
ASUS P8Z77-V, Intel Z77
NVIDIA GeForce GTX 780 3GB
8GB Kingston DDR3-1333 (2x 4GB)
1TB Seagate Barracuda
600W - Corsair GS Gaming Series
IIYAMA 27" 1920*1080 Prolite G2773HS/
Wheel: G27
Win7 64 bits

I noticed an anoynig noise coming from the power (600W Corsair GS Gaming Series)
I noticed that the noise is there when the number of FPS is high (400 FPS or more)

In the Nvidia control panel, when I choose Vsync "adaptiv", the noises disapear (I have then a max of 200 FPS and an average of 120 FPS, sometimes 75-80 FPS)
Paradoxaly, I have to say that the video quality is better with Vsynch adaptiv (max 120 FPS) compare to Vsynch out (400 FPS or +)

I made the test with the game Formula Truck

My question: are these noises normal? or should I give it back and let change the power supply "600W Corsair GS Gaming Series"? (it's under guarantee)

Is it a pity to to play with vsynch with a GTX 780?

Thanks a lot for your advices.

Hi,
This noise is probably made by coils inside CPU/GPU when they are under heavy load. It's pretty common thing and won't damage your hardware.
You should notice it especially during some intro movies (usually computer is rendering them with even 1000+ FPS)

If it is annoying you just cap FPS to your monitor's refresh rate.
