Strix Vega 64 Mega coil whine

[28BeersLater]

Hi Folks,

I recently swapped out my three EVGA watercooled GTX-980 SC's for a single Vega 64 (I was fed up with Nvidia's awful driver handling of triple wide / extended desktop configuration)

All in all I'm happy with the new card, in most cases the performance is on par with the previous three cards, but I'm suffering really terrible coil whine in certain scenarios.

If a game is minimised, or on the menus of some games (PUBG) the whine is excruciatingly loud. - the cat leaves the room - in other games it whines and hums a bit and is the loudest part of my PC, but is almost liveable with.

I haver a EK waterblock for it currently unfitted) and don't want to do anything that might invalidate the warranty until I'm 100% confident in it.

This single card is much louder than all three GTX 980s in an otherwise quiet PC. The power supply is a Corsair AX1200, and is more than man for the job.

Has anyone else suffered this?

I think me and you are in a similar boat, except maybe my issue is slightly worse.

Mine randomly shows me a screen that is locked up or a black screen (no input)

Granted, my PSU is a Corsair AX750 which was brought in February 2013. What age is your PSU?

Whilst writing this post it has done it twice to me where I touched my PC case accidently, which now makes me wonder if there is an earthing issue or similar?

My PSU is also quite old - Corsair AX1200... but it's a decent PSU and happily coped with three GTX-980s at max chat (showing 1.3kw draw on my UPS!!).

Update,
I'm running a completely new build, but retained this GPU, now on water cooling.

As before the GPU runs dedicated PCIE connectors from PSU to GPU.

Brand new Corsair SF 750 PSU. it whines just as much as before... No reply from anyone at Asus?

aaand the GPU has failed.

RMA time.

RMA rejected because I had run a watercooling block.

Come on Asus, this isn't really good enough. EVGA allow water cooling, ROG is meant to be an enthusiast brand too.
