Years ago i had this:

ASUS TUF GAMING X570 PLUS
3800x
GIGABYTE RTX 2070 Super White Gaming OC
CORSAIR AX860 PSU (Fully modular)

It was all great till the GPU coil whined but i thought "Time for a partial upgrade".PSU had NO issues...Big mistake

Everything in the list above and more was kept except the 3800x to a 5800X3D, a CORSAIR RM1200x SHIFT and a GIGABYTE RTX 4070 Super among the CPU fan cooler to a bigger one (Noctua NH-D15 CB).

First 5 months all great. No CW on anything

2 weeks ago the PSU decides to "say hello" and cause CW. More noticeable if i put a game like MARVEL's GOTG or DOOM ETERNAL on the main menu or a random level with no enemies around. Even moving the mouse around caused a variation of the noise

So i thought "Maybe i could try a smaller PSU from the same brand n model as many people do!". 850W bought 2 days ago. Popped it in and no CW until 3 hours passes and tadaaaa, another CW in record time!...Returned the PSU immediatly yesterday and refunded (They tested it in my face, all smiling..."Maybe it's something else from your PC that won't turn on!". Had to lie or else CW reason would be DENIED)

I tried an "OCCT" with the POWER option so far and before starting it the CW was there. Started the test and the noise didn't went up but the entire PC became an oven in my Be Quiet! DARK BASE PRO 901,so i turned the fans to the MAX just in case. 1H th test ended and 2 minutes after the noise was gone.. Until this afternoon today it came back here and there

The noise is ear and brain hurting as i am very sensitive. I can't use a headset for reasons. The high pitched noise or whatever it makes is driving me crazy

I want to know what can it be done. I can't return the 1200W unit because "Coil whine is normal, don't worry" MY REAR!...I had to lie with the 850W one above FOR ONCE to prevent the same answer and get the refund

This PSU was suggested to me months ago along a Be Quiet! STRAIGHT POWER 11 one but then the BQ ones, old and new, are said to either have CW or even worse: Rattling fan.. And nothing has been said if they fixed the issue just yet!

And then the same CORSAIR PSU is in that Tier A list from that PSU tier guide

Below you can see vids of both game and IDLE (Yes, IDLE is the worst thing here) causing the noise. Forgive my awful voice:

Thought of putting some recent proof. The PSU has been quiet for 5h until now...Most of the time on Idle

All cables (minus energy socket one) removed. The noise is still there. Tried different wall sockets. Everything the same

I did some video encoding but while it was being done , and after returning home, there was no CW at all ...

PSU still coil whines after every component is unplugged

Yeah well, the issue comes and goes here but when it's on it's desperating and abnormal and i haven't been productive at all because of it (I've done more research than doing things)

People says to try another brand like Seasonic although some people using FOCUS or VERTEX from em also seems to have the same issue but it might be bad luck or something

What can i do?.. And the whole C-States i'd rather not touch due to energy increasing (power bill) . I've already rolled up a paper with a stick to use to pinpoint the Motherboard everywhere and no noise came out from it so it cannot be the MB, although someone else mentioned that changing their MB solved their PSU issues but... https://forum.level1techs.com/t/eve...-whine-to-come-from-the-psu-s-edit-yes/209200
 
The only setting in W10 related to energy is to prevent the PC to go hibernate/sleep/whatever makes it shut down or make the screen go black till the mouse is moved. These things back then occassionally made the internet to lose connection or cause some issues when slapped awake

I mean, if the PC gets turned off (No hibernation nor similar. Simply 100% shut down) then the noise from the PSU remains but vanishes in a matter of minutes i guess, slowly (I am not there to witness that due to home tasks), and stays shut/quiet until i power it up again and comes whenever it wants

Hopefully that explains my situation a tad bit more. And yeah, the C-States thing...I mean, if i can't hear a thing from the motherboard itself (surrounding the huge Noctua NH-D15 CBlack or the huge GPU, AND EVEN FROM BEHIND (right side of the tower WITHOUT THE PANEL)) with my ear sticked to it or with a tube (I don't want to unscrew the MB off the tower...) then it's a cat and mouse game
 
Today i've spent like 3h with a very tiny coil whine from the PSU and i barely heard it from the distance (I usually checked from time to time), but after that the noise ramped up again. I'm starting to give up hope on this but i need to solve this issue..

But i've read that disabling the C-States causes an increase of the power feeding, meaning that, well, the electricity bill could rise up some and i'd rather not risk it in case it also does something wrong to my components..

The plan is "Balanced (Recommended)"

Some people recommended me, in case the worst happens (No solution after any possible solutions), to try EVGA, ASUS or SeaSonic PSUs. I've read that SS are "the origin of the PSUs" or something (where other brands grabs their PSUs and changes stuff here and there) but i don't know.. I still saw people complaining about issues, even recent ones, on FOCUS and VERTEX models but... uuuugh, i need help, seriously

Thanks for the help so far btw
 
I did a quick test. Downloaded DOOM ETERNAL (once again) and played it on the menu and a random level without enemies WHEN THE PSU DIDN'T DO THE CW (Aka powe the PC and run to the game before the PSU CW happens).

When playing the menu/level the GPU did it's usual CW due to FPS etc (Again, limited to 120hz/FPS) and moving the mouse around did vary the buzzing sound FROM THE GPU but the PSU did NOT had any noise from it

Can the GPU be discarded from this point?...
 
I apologize for that. I've not been feeling a bit well because of all of this.. You can imagine...

Ok, i went to my BIOS (ASUS X570 TUF GAMING PLUS) and followed a tiny guide: Advanced->AMD CBS-> Global C-States

That's the only option and only allows me to disable, enable or auto. There's no single C-State 1 or 6 or whatever other people mentions on the net tho..

I tried DOOM ETERNAL with the speakers turned off and slowly the PSU noise vanished (Although it was already low but there the moment i changed the setting) but i don't know how long it's gonna stay quiet...And how it could impact games or whatever... Or worse of all: THE ELECTRICITY BILL...

Note that when i disabled such option the mouse still caused varied buzzings to the GPU when moving the mouse (When some people says it helped), if that kind of helps pinpointing things out, but even with the speakers off i barely was able or be bothered by the GPU...

I'd like to know what other things i should do in case the PSU's CW returns or try other C-State settings or whatever to minimize the waste of power (and increase of the bill...) while keeping the PSU CW away

Or check other BIOS settings that i might've skipped...
 
My head hurts from thinking too much, please bare with me ==;;;...I was happy and now this crap happened

The noise progressively disappeared?

Can you list exactly which situations cause the noise to be better, or to be worse?

When i was doing the C-State thing in the BIOS the PSU's noise was there, but in a matter of minutes it vanished once i've saved the settings into the BIOS and rebooted the PC, making me think the C-States did something and results in 2h of silence, but as ya can see it came back..

I could power up the PC after hours of being 100% turned off (PSU is silent when it happens because it probably discharged all the frigging whine after powering it off) and it could take minutes or hours for the noise to come up. It is completely random as to wether it goes better or worse, wether it comes sooner or later. but the moment i can hear it the most is on IDLE or doing light tasks like browsing, etc... You've already heard the noise in different situations above, and again i started the PC all cold , rushed into DOOM ETERNAL and the GPU did the noise but not the PSU...

The sound is more noisy if you approach to the PSU's behind where the power cable is connected when it happens. If i put the ear right on the connector's plug area of the PSU, almost touching it, it is the most electrical loudest part that there is, so maybe it's some connectivity issue but not sure if a different power cord will solve it (CORSAIR and anyone else always says to use the cables that comes with the box, so...)

I didn't said this but the power sockets on the wall are 220V (Used an AC detector thingy, sticked 2 sticks HARD into the holes and it said 220V). They don't seem dirty and they're security sockets, and i already tried different sockets on the walls with the same results. Same goes if i carried the PSU away from the tower (All unplugged minus the power cord) and plugging it on other parts of the house while the PSU still had the noise in it. Noise appears only when connected (It tries to fade away the noise from use) but vanishes completely if unplugged

I might've said some parts of the above already again but better remind about it...
 
Is it possible that some Air Conditioner from the house could be provoking the coil whine?.. We have 4 down here (1 in my room, 2 next to my room, 1 more farther away) and i was told somewhere else that even with the PC turned off that the CW on the PSU could be caused by them

Because the PC has been powered off for like 30 or more minutes (had lunch 4h30min ago from this post's timing) and the CW was there when i returned (Still powered off btw) and the AC from the dining room (farthest one) was the only thing that was turned on, along a standing fan. Right now as i type the dining room AC and fan are off and the noise's gone, although my room's AC is turned on

Maybe there is really something in the house that causes it?... Although i've noticed today that i forgot to turn off and unplug the printer yesterday and whenever i approached it it made some light coil whine (If the power up light blinked then the noise varies also)

Could there be a connection then?...
 
I completely have no idea... I'm no engineer and don't have the knowledge etc (A noob in this area...)

Anyways, let me tell ya. I have 4 ACs:

-My room
-Parents' room
-Guest room
-Dining room

(Yeah, that's a lot...)

If i connect my room and wait 1-2 mins nothing happens. Same goes to the parents' room. Same goes if both of the mentioned ones are turned on (Each has a different cold Celsius!, but they run at full speed)

However, if i turn on the guest and dining room ones, (one first, turn off, then the other, then both) they provoke the coil whine on the PSU...

Even though, i think, their installations are located outside of the house (Walls), they're the culprit of the coil whine... If that's the case, the PSU must've always been working fine and all great because 5 months ago there was cold environment and we didn't needed the ACs to work while building the PC etc!

I'll tell my parents and will let you know what's their decision, because our kitchen's fridge does something similar (I think) and it could help reduce such noise. I know i know, coil whine doesn't kills the components (unless the noise is enormous and could mean big trouble) but for my ears and the house's safety...Well, let's hope this is the cause and hopefully we or an engineer can fix this frigging issue

OF COURSE i appreciate the help so far and i deeply apologize for some of my behaviours (Specially the C-States, wich have been turned on Auto again just in case...).
