PSU coil whine when under load

[Feris]

My computer spec:

CPU: I7 7700k
GPU: Asus Strix 1080ti OC

SSD : Plextor S1C

HDD: WD Blue caviar

PSU: Antec EDGE 750W

my PSU is very silent at normal use but when start high settings gaming, it start coil whine sound, is it dangerous ?

I don't know it because my wall socket problem or my PSU cause when i use voltage regulation tool it still there but low volume.

The wine won't hurt anything. 

 

You sure it's from the power supply not the cpu or gpu?

yup i am sure the PSU cause the noise

Coil whine is harmless, albeit annoying. My PSU has coil whine, still going strong after over three years of use.

Coil whine can be annoying, but normal, nothing can really be done about it (Nor will it damage anything).

I had a cheapy 600W that did that. It bugged me so I got an old 800W (of a different brand) and it went away. Coil whine is not bad but is hella annoying.

 

If you dont want to chang PSU. You could try locating the inductors and put super glue or hot glue on them. Or maybe try adding more load using fans or something to see if that changes it.

k thanks guyz, cause before i never has this noise so i worry

This issue is unlikely to damage your PSU unless you use it A LOT.  It doesn't mean there is a lot of extra strain on your PSU.  It is similar to "Hissgate" when the iPhone 7 first came out, annoying but not harmful.  The only real option would be to get a new PSU, because you wont use much less power from undervolting and won't want to change to a more low power part just for the sake of more quiet operation.

not that loud is like wind go through hole but when i put my head phone on i don't hear anything

Most likely you are getting coild whine because of GTX 1080 Ti.

I had R9 390 before and when at 100% load, there was no coil whine at all. Now I'm using GTX 1070, and I hear coil whine on GPU and PSU. So it's not PSU problems in my case, because R9 390 was pulling more power from PSU than GTX 1070 right now.

It's also possible that your GPU is causing coil whine to your PSU, but it doesn't have it itself.

 

It won't harm anything else than your nerves because you have to listen to that annoying sound lol

i kinda overpower my rig with that PSU i sure not from my Strix

I personally had of severe coil whine with a previous Aero Cool Interrogator 850w PSU, a notably horrendous PSU for surge protection standard. I later replaced of it for a completely overkill Corsair RM1000x, to which solved of the issue. Although I would suppose that is courtesy of it being never under 'load' with this system I have of, as well as a far superior efficiency rating..

Well, coil whine can happen with any PSU really, regardless of quality. I personally have a Corsair AX860 which is a very good PSU, but it's had coil whine since I first got it. Not noticeable when idle unless you put your ear near it, but under load you can hear it a bit. Efficiency rating and wattage don't really effect it, as mine has coil whine all the time, even when idle (as mentioned, it's quite though) and it's Platinum efficiency rated. Just luck of the draw for the most part.

PSUs can have coil whine but it's more likely your GPU. If you plug in your headphones to the front panel audio in your PC do you hear the coil whine in the actual sound coming through your headphones? My GTX 970 has horrendous coil whine and my headphones reproduce the whine through their drivers if I use front panel audio and thus I use an external amp/DAC.

no i plug my headphone in the front not like you , i am sure that my coil in PSU cause it

Man you wanna hear coil whine ? Run the Vulkan API draw call test on 3DMark with an AMD card. My 390 sounds like a sack full of dying rats running that test, in fact i got really scared the first time i heard it, PC's shouldnt make that noise man
