PSU Buzzing After GPU Upgrade. Help!?

[botfly10]

My PC:

i7 4790 at stock 4.4

Asus Maximus Hero VI

16 gb Crucial Ballistix

Corsair HX1050 

 

My Issue:

Put in a new gpu and after ~4 hours of gaming, PSU started buzzing and whining.  Now makes sound during all games.

 

Details:

I recently upgraded

from: 2x Asus 780 OCII in sli

to: Asus 980 ti Strix OC

 

So, I put the new GPU in.  Ran Kombuster to check for coil whine, fan issues, and general problems.  Card ran great, no issues.  Then I played about 3 hours of Rise of the Tomb Raider (that eye candy tho).  Again, no problems.  Ran great - quiet, cool, beautiful in-game experience.  Then I started playing Knights of the Old Republic.  After an hour, I heard a buzzing noise.  I investigated and the noise is coming from the PSU, with most of the sound venting out of the back of the PSU.

 

The noise is mostly an electric-ish buzz that almost sounds like something is clipping the fan (its not, I checked) along with a fainter whine.  Both sounds change pitch when I rotate the camera in-game.  All games now cause this sound to occur, though to varying pitch and loudness.  When I open a fullscreen menu in-game, the sound stops in most games.  When I click "quit game", the sounds stops immediately.  I get no sounds when doing other things on my PC, though I don't do anything demanding besides gaming.

 

I never had any buzz/whine issues over the last 2.5 years while running a single 780 or two 780s in sli.

 

I do not have access to another PSU to test without buying one from a local store and then returning later.

 

I think I am going to RMA the PSU on Monday and cross my fingers...

 

Questions:

1. Is RMAing the PSU the right thing to do? 

2. I now have 26 days left to RMA my 980 ti through newegg before I have to deal with asus RMA.  Should I go ahead and RMA my card as well, just to be safe?

3. Is it possible that I just have an unlucky mobo, gpu, psu combination that is going to produce this problem no matter how many times I replace individual components?

 

 

Thanks for reading!  I posted this here cause of how great this community is.

The weird thing is the 980ti should take less power than the 780s. If you still have them, test one, and then two 780s and see if the problem continues. You may want to do a gpu stress test and leave it for the same amount of time it took it originally to start whining. Try this with both the 780 and 780sli, and then the 980ti oncemore. 

 

If you can, swap the psu with a friends and test. Also, try to redo all of the cables in the system, and check your drivers (while this is an unlikely issue, you never know)

 

EDIT: I kinda skimmed over the post a bit. So I didnt see the part about swapping psu. 

 

In this case, I would get a new psu, and if it does the same, return the new one, and look at where else the issue could be coming from

Well, I have been googling a lot and it sounds like this is not actually a sign of the PSU being faulty or near death.  I have read in multiple locations that sometimes a certain combo of components will pull power at just the right frequency to cause psu buzz.  Or something like that.  Not sure if that is really possible though.

Coil whine?

[botfly10]

Well, I tried single 780 and 780 sli.  Neither card buzzed.  The psu did buzz with the same sound but only with my ear basically on top of it.  Definitely could not hear it with the case closed.  I don't think this really tells anything.

 

Guess I will buy a new PSU from a local store tomorrow and test with that.

 

Do stores normally take opened PSU's back?

So put in an RMA for the psu.  We will what happens with the new one when it gets here.

Quick question, are you going to put up those 780's for sale?
