Hi guys,
 
Need some help with the trouble shooting process..
 
I keep getting - I think - coil whine from multiple GPU's
Here is my setup:
8700k
Asus z370i
16gb 3200mhz corsair vengeance memory
2x Samsung 960 512gb m.2 ssd's
GTX 1050ti
Corsair SF600 PSU
 
With this setup I get no coil whine.
Placed a GTX 1080FE in the computer and it hisses under load, tired a second and 3rd - still hisses, Had Nvidia replace it twice. Still hisses under load
Tried an EVGA 500w and 650w psu, and it still hisses
I have a case that requires a PCIE riser/extender - got a replacement one, still hisses.
 
Tried ALL of the gpu's in 2 other computer and they hiss under load in those too.
 
Got an AMD RX 570 and that hisses/ticks (different noise than the Nvidia cards).
I replaced the corsair PSU with a brand new one and it still makes the noise.
 
Only card that does not make noise is the GTX 1050 ti - which does not require a 6 or 8 pin power connector - it gets its power from the board.
 
I'm at a loss to figure out what is causing the hissing - I've been waiting to water cool my PC due to the noise as it will run silent, apart from the damn hissing noise from the GPU when under load - games and benchmarks do it.
I placed my wife's GTX 1080(EVGA FTW) in my PC and it did not hiss.
A while back I had a GTX 1070 and it worked properly without issue.
 
I'm wondering if I am missing something, or if I am just extremely unlucky and have had 6 cards back to back all have loud coil whine.
 
 Any input is welcome
 

Actually Hardcore Overclocking is very indepth.

PSU cables are correct.
PSU is installed correctly with screws.
Whine is definitely coming from the GPU - only when its run.
My monitor is 144hz,  tried setting it to 60hz and it still happens.
 
Will try a different power strip and outlet - its about the only thing I haven't tried.
 
I've literally built hundreds of PC (used to do it for a company).
I only ever have issues when building my own lol.

Reason I said to pull the board and put it on the table and run it was to eliminate all outside stuff - just the board, GPU, PSU and OS drive (any drive that has a linked program for that matter)
It is rare but I have seen people that had persistent coil whine on their GPU's and it ended up being and actual issue with the MB, may have been an defect in the VRM on the MB introducing noise on the 12v line which caused the inductors on the GPU to get mad.
Or put the GPU into a different system and see if it still made noise

Tried a different outlet, and also replaced the mainboard, and got a RTX 2060 - GPU coilwhine / hissing/scratchy noise remains.
Also tried different memory. At this point the only thing I haven't replaced is the CPU.

The house was built in 1926 - so the electrical is very dated.
 
Do you think a UPS would remove the coil whine if it is due the electrical?

you would need a power conditioner to clean up the power - can get expensive
