Is this the sound of coil whine???

[Goliath_1911]

Hi , i know coil whine is generally not much of an issue but recently it started to make a weird sound for a couple of seconds as soon as a load hits it, but then fades out, it is in the video below

Can someone confirm if it is indeed coil whine ??? I can`t tell if it is , help is appreciated!!!

 

EDIT: forgot to add its a coolermaster masterwatt 650 80+ bronze

Sounds like it to me.

Yes, that is coil whine. Typically not a bad thing, mostly just annoying.

You could try, they'll likely just send it back to you or send you another unit that may have the same issue or be in worse shape, depends on what they have in stock usually when you RMA and they replace the unit they send back another RMA'd unit that they repaired, so it will be used and sometimes they can be a little worse cosmetic condition than what you sent in. Plus right now with whats going on most RMA centers are closed, so you'll likely get the RMA accepted and send it out and wait a month or two at least to get the used or same unit back. In my opinion if it doesn't bother you just deal with it. If it does buy a new PSU. I, especially right now wouldn't recommend RMAing it.

i don`t mind the sound as it`s only there for a like 10 secs, but i was worried if it is something faulty since this rig is new , barely 1 year old , and i just recently installed a new gpu so was afraid of something getting toasted,

Also i was wrong in saying the psu is 1,5 years old , i did get it 1,5 years ago but i installed it when i got all the new rigs parts so basically in use for barely a year

 

so i guess i will forget about the RMA

If you used the PSU with a low power GPU and then get something a bit beefier coil whine can happen. Some people say you can get rid of it by "breaking in" the components. Running some intense stress tests for a few hours or until the coil whine stops. If the coil whine isn't loud or constant I wouldn't worry about it.

well i did jump from a 1050 ti to a 2070 super (old gpu was in the new rig for like 7 month)

It happens when the power usage increases massively(start a heavy game) , but goes away after like 10 secs

Coil whine is minimal , i couldnt tell if it was whine or something else tho, had me worried for a bit .

Thanks for your help!!!

If the PSU is new, I would just return it under the return policy of the store, and buy a different brand or model. The reality of things is that manufactures tries to avoid coil whine, at least on their non-budget products. But depending on your system configuration and power from the wall. It can happen, and there is no fix, beside trying a different configuration of components with differing circuitry design.

 

Personally, I hate coil whine. If it is constant, it gets annoying real fast, and if it fluctuates like yours, it sound like a HDD under load and is annoying. But then again, I am all for computers that are ultra quiet operating. Ideally, if possible, one should not know if the system is turned on or off by it's sound, at least at idle. It is a computer not a car engine. But that is just my view.

well it`s been in use for a year, though it is still under warrenty, as said above due to the  covid situation it might take some time for one to get sent back

Also for some reason in my country almost all stores sell AeroCool psus which from what i heard are not that good, and risky, this coolermaster one is the only psu i managed to find that is not Aerocool lol, i might just hang on this one for a while, and import a seasonic psu when i upgrade my cpu (planning to jump from the i5 8400 to 9900k)
