Hi there,I have problem with my PSU that worked flawlessly for the last 6-7 months...But,now,since I upgraded to Asus rampageVI and i9 7900x it started producing this strange sound,like short circuit buzzing sound.
I haven't done any OCing on my PC,I'm running 1080ti aorus extreme edition,custom waterloop,two m.2,usb splitter nzxt,D5 pump,NZXT grid fan controller and Hue+. On PSU I have connected one 8 pin EPS and 4 pin CPU,mobo cable,2x8 pin PCIe cable,1x3x molex and 1x1x sata connector.
Corsair Link works.My system didn't shut down,or crashed,my GPU worked before with the same PSU. Everything runs fine,but that sound isn't coil whine,it's disturbing,and I don't know how to check what is wrong.Corsair support is non existent (nobody replays on FB page,can't put ticket on corsair site nor anybody responds on their forum,it's like they don't exist)
I honestly don't know what to do....Any advice would be very much appreciated even suggesting buying other brands PSU.

Yeah make a recording. That is a very sophisticated PSU, if there was a short circuit somewhere especially one capable of producing noise then the PSU or motherboard would likely detect it and not allow the computer to power on.

Sounds like coil whine, if so it is not a short circuit just coils inside the PSU hitting a resonant frequency and vibrating. This is not necessarily dangerous and is quite common, but annoying. Hard to say what is causing it could be simply the different type of load your new system is putting on the PSU. There is typically nothing that can be done about it unfortunately.

You can try to RMA the PSU, but no guarantee your replacement wont do the same thing.

GPU's are also notorious for producing coil whine, especially when a game or application is running at an extremely high framerate such as in a game menu with vsync off.. Are you sure it's not the GPU?

No,I'm sure,V sync is always on anyway,and my GPU coil whine is very different from the sound my PSU makes.My main worry is that this is something dangerous...I need to record it and post it here.But,my system is stable,I didn't have any random shut downs or BSOD...
