I have a brand new 780 Ti and have noticed now that depending on the game I get coil whine from my system. I have found it only really happens in benchmarks or with applications not very stressful that produce high frames. I did not get this when I had the GTX Titan. I am using a Corsair AX750 Gold rated power supply.
 
Since the only thing to change in my system is the video card, I guess my new 780 Ti is the culprit? Or maybe it doesn't like my power supply like the Titan did? Could changing power supplies resolve?
 
Suggestions? Both the power supply and video card are still under warranty for RMA.

You didn't mention which PSU you have but based on my own personal observations a well regulated PSU can cut down on some of coil whine compared to a PSU that is poorly regulated. You can still have it though and that doesn't mean anything is wrong. However if you have any doubts you are always welcome to contact EVGA tech support.

My first 780 Ti had coil whine. Got my replacement yesterday and there is still coil whine! The only thing in my system that has changed is the 780 Ti. I had a GTX Titan SC+ in the same system and it was silent. For the heck of it I tried a different power supply and still got coil whine on both cards. The power supplies I tried are the Corsair AX750, which is Gold rated, and the Corsair AX760i, which is Platinum rated. The AX750+Titan combo worked perfectly. The rest of my system consists of a 3930k CPU, Corsair H80i, ASUS Rampage Formula X79.
 
Is it possible there is a bad batch of 780 Ti? I have noticed the serial numbers between both cards are not very far apart. I am not the only one reporting it, as seen here: http://www.youtube.com/watch?v=3PMcmOxZ7_0
 
I'm very sensitive to this kind of noise as I built my entire system to be as quiet as I prefer, which makes things like coil whine or electrical noise easier to hear. I guess I am going to have to try another RMA. As a final test, I am organizing to get one of Corsairs new RM series power supply which they are promoting as being silent and specially designed to eliminate any chance of coil whine.

i wouldn't accept ANY sort of noise.
RMA it.

I did contact EVGA and they are arranging another RMA.

I would REALLY like to know an answer to this. There are far too many people encountering the same problems. And the coil whine on mine is really starting to bug me, especially in CS:GO. I put a limiter at 120 which seemed to fix it for a while, but now its starting to do it when it hits 120 in certain titles. I didn't know they actually RMA because of it. Knowing my luck I would get one back that has it even worse.
 
 
 

Well, I had a EVGA 580, 680, Titan and they never had coil whine, or at least it was quiet enough not to ever hear it. But with the 780 Ti I can hear it in both intensive apps and non-intensive ones. So for me, having never really encountered it, it is hard for me to accept it now.
 
I've tried 2 780 Ti now and both have whine, I am hoping the 3rd will be a winner.

i got my self,not to long ago a 780 ftw and it only whines in 3dmark13 in the firts part that have benchmark after that its fist.
i dont have it in any other thing that i do on my computer..hope its stays like this then i dont mind..but its not the way its supposed to be.
for this kind of money i like a quiet card.. ill see how it goes..otherwise its going rma to 

I had a 580, 680, Titan and none whined in 3dmark. But the 2 780 Ti's I tried do. Not right.

I had coil whine when [link=mailto:folding@home]folding@home[/link] with both GTX 560ti running, and sometimes with just one running.
It sounded like it was everywhere.
I listened to it thru a cardboard tube to locate the sound source. It was the power supply, not the cards.

I recently had this problem with the 780 HC and it turned out to be my brand new PSU was bad as it died about a month after I posted here about it; since getting the PSU replaced there's no more coil whine. I really think the two are related since I have never once heard it again after getting the PSU replaced.

Both of my 780Ti Superclocks have nasty coil-whine... pathetic.
 
Now my only option is to pay to have them shipped internationally across the border to California -- then I'm charged a 15% re-stocking fee on top of the shipping I have to pay. I will never buy another EVGA product, period.

Coil whine is really nasty phenomenon...
Worse of all is constant high frequency coil whine when noise is always same no matter on load or power consumption.
Graphic cards more often squeal or whine during load at that's little different noise.
But and PSU can whine similar under load when graphic card pull power but worse is constant coil whine, like high frequency far-off buzzing.
 

Hello, I submitted a week ago a advanced rma request of my whiny card. Today I got the new one and has the same problem. You can say that it isn't harmfull but I don't want it to have it. I want a perfect card. Because of all these that I hear on here, the 780ti and 770 which are new has this problem. Titans and 780 doesn't have any. Can you eventually send me a not coil whine card or I can return both of them and refund me? How am I going to ship them because ups courier doesn't exist in my area? Last week I talked with support center and said that will be arrange an ups pickup service. How about the shipping cost?
 
Thank you in advance and sorry for my bad English

It's possible changing power supplies might resolve it, but no guarantees.  I would use the card, running lots of benchmarks and gaming on it, as the coil whine could go away as the card is "broken" in more.  If it doesn't go away and becomes just too annoying, you could RMA the card, but there is no guarantee the next one won't do it as well.  A temp solution would be to use vsync or target frame rate in Precision X to keep the frame rates down.

It's not harmful guys. I'll tell you how to fix the whine, leave the card running for 36 hours straight on some game or benchmark where the coil whine is at it's worst, make sure to have the fans pumping @ 100% when you do this, after 36 hours the coil whine will be gone.

I had coil whine on my 260 and it never went away. I put a lot of time onto that card too. 

You may have put a lot of time onto it, but did you run it at it's worst coil whine point for a straight 36 hours?

my coil whine is so loud, when i play ac4 black flag it is just mega loud.... unbelivable loud, the fan is on 45 % but the coil whine is much louder... Shame on them both, Nvidia and evga that they try to sell that crap crads to us. im really mad atm, this coil whine is not during benchmarks, it is during i play ac 4...

If it is that loud and it bothers you request an RMA. EVGA should replace it if it really is that bad. I've experienced much more whine and odd noise from non-reference style cards compared to reference, for whatever reason. My 2 reference 780 Ti SC's have no whine.

I'm disappointed in EVGA. I went to Fry's (first one was from Amazon and is getting returned) and the card I got has the same exact issue. EVGA is pumping out some crap 700 dollar cards.

Coil whine does not indicate that the cards are crap.
