Aurora R6 - PSU Buzzing - Replacement did not correct

Aurora R6 - PSU Buzzing - Replacement did not correct

About 2 weeks ago I received my new Aurora R6 with the following specs:
 
Intel(R) Core(TM) i7-7700K CPU @ 4.20GHz
16GB DDR4 2400MHz
128GB M.2 SATA SSD (Boot) + 2T B 7200RPM SATA 6Gb/s (Storage)
NVIDIA(R) GeForce(R) GTX 1080 TI with 11GB GDDR5X
850W PSU Liquid Cooled Chassis
 
As I was busy after it arrived I did not do much on it for the first week but once I had the opportunity to do some gaming I noticed a distinct buzzing sound coming from the case. This was mostly only evident when pushing the system a bit playing games such as Mass Effect Andromeda, Wildlands etc. After troubleshooting a bit I found that the buzzing decreased if I toned down the graphics options. Immediately I assumed this must be from the graphics card but further diagnosis indicated the sounds was coming from the PSU. I had a DELL tech come out and replace the PSU but the buzzing sound is still present. It is without a doubt, coming from the PSU even after being replaced.
 
I am now waiting on a new system being sent as DELL wanted me to send this unit to a repair facility but, even given the sound, I cannot be without a system for at minimum a week.
 
Although I will be getting a replacement system I am interested to hear if others have had a similar experience. The buzzing sound is definitely coming from the PSU (and the second PSU) BUT there must be a different component causing this.  Thoughts?
 
Thanks,

James

At the end of the day it's resonance that's causing coil whine on the GPU.

so, your GPU is causing it.  I can't really explain why as it's pretty complicated.  (Electricity isn't simple, in fact it's mostly imaginary)

Dell will replace the GPU and send it back or send it to someone else as factory refurb.  In the hypothetical that it's not the GPU, then it's another component which can be replaced.  The component they replace will probably work in another computer fine. You can look up resonance on Wikipedia and maybe understand it more than I do. (Also coil whine on Wikipedia).

Cheers!

Oops,  I said GPU in the first sentence when I meant PSU.  It's causing coil whine on the PSU...

There are two 850s from different vendors: name-brand Delta N1WJD is preferred over no-name Huntkey 48Y6D which tends to have majority of issues. It is advised to pull it out, check which one they snuck in there (good one vs cost-cut one). When Huntkey has issue, demand Delta replacement

Thanks for the responses - the replacement system is on its way, until it arrives I will suffer the sound.

Once I have the new system I will have a look at the PSU and see whether it is a Delta.

So was it a Delta?

Was the issue resolved?

So I've gone through three replacement Deltas. The Huntkey brand is apparently the one you want. It's on it's way here, and should hopefully fix the issue.

the Delta power supply is a Bronze rating. It's the cause of the issue, and it's well known with this PSU. Switch to the Huntkey, or buy yourself an aftermarket Seasonic 850W Platinum.

'maybe' ... the HuntKey was the 1st PSU to have noise issues, causing the owner's base to seek out the brand-name Delta (search Huntkey noise, plenty of complaints) ... a little role-reversal going on now huh? HKey / Delta both have a Bronze certificate. The 'well known issue' should be 'the 850w in either flavor are both afflicted w/noise issues' > 'even the warranty replacements are bad' (a common complaint) ... good luck with yours
