Is my Coil whine from my Gpu or can it be from psu?

[gardenlight]

Hi.I have tried 4 gtx 1080 graphic cards and 2 gtx 1080 ti all different brands and all of them have had coil whine.The last one I got now it's realy loud on so I wonder could this be the Psu and not the gpu's fault?
My pc specs are:asus gtx 1080 ti rog strix oc,32gb memory/ram,i7 7700k,asus rog z270h moatherboard,Cooler master v1200 1200w psu.

do you mean like a bzzzt sound by the phrase "coil whine" ?

 

[gardenlight]

A very high pitched buzz sound yes

 

[timmy_area51]

well , since your card is nvidia i might not be eligible to answer your question . but in AMD cards it's an uncapped fps that causes the bzzz sound . the fix is in crimson . there might be a similar fix with 1080's cause they say multiple cards result in higher fps . so you gotta go to the SLI settings see if you can limit the fps the produce !

I have caped my fps with nvidia inspector so its around 100 fps but even at 40 fps the sound is still there.

well what wattage does your psu supply ? you need tons of powers for 4 1080's like you mentioned . could you post a pic dude ?

It is often a combination, but usually the psu is the most prone to coilwhine... try another unit. a way to test this is if the sound changes under load. My psu caused coilwhine when scrolling while browsing and when gaming.

what I ment was 4 different 1080 cards not 4 at the same time and now i have tried two different 1080 ti's with the sme result.my psu is 1200w as i mentioned

And unless you plan to run multiple gpus there is really no need for 1200 watts.

 

[timmy_area51]

you can enter your different cards with other stuff you got in pc part picker or more accurately in cooler master's wattage calculator . that gives you the proper wattage you need . if your wattage is enough then it should be your combination of different cards , or maybe using two ti's with two 1080's ??!?

If this is the one youve got? only 1200 watts i could find on jonnyguru.

Evga has some nice Titaniums.

Thanks the evga one looks very nice I think i try something other than cooler master now.

well taking into consideration your rig I deduced that you didnt mind higher end PSUs 😉

 

[gardenlight]

I prefer to buy things with some quality yes so I don't have to buy upgrades in several years

Try to borrow different PSUs from your friends and test it!

Let me tell you my experience on GPU coil whine nightmare:
PSUs model:
- Corsair HX620W
- Corsair RM750i

- GPUs: Zotac GTX. G1 Gigabyte GTX 970. Galax GTX 1070 Ti.

All combinations resulted in very loud GPU coil whine !!

Solution to my case: EVGA 600 W. No more (loud) GPU coil whine. 😀

Good luck buddy. I know how exhausting this is... 🙁
