Psu coil whine is there a way to stop it?

[sisrace]

Hello, So my desktop computer is from 2009 its now 4 years old, lately i started investigating why this super high pitched noise keeps whining in my ear, so i opened my computer and started listening on some of the parts, i found out that it was the psu, The coil whine only comes up when the computer is in windows and while gaming, But when its starting up or shutting doen its quiet, I think this is becouse im almost overloading it or something but i really shouldnt, its using an 90W amd cpu and a engt 430 gpu, it draw's like 150-200 watts at its max and i bearly pushes it that much, even with gpu and cpu at max the computer is running fine,
the psu is 300W so im almost maxing it but still, it should not whine like this. Can i fix the whine in some way? i heard you could put nail polish on the capasitors to stop the vibrations and the whine came from vibrations or something...

If you desktop power supply is making noise and its not the fan Replace it. Do not try to fix it. A power supply can hold voltages for a long time that can kill you.
From you post #1.

Whatever you do like that would most likely cause the coils to overheat more and I wouldn't even try it. To me that sounds like the PSU is about to fail. Research a more powerful PSU for your machine. My old Pentium 4, back in the day, used to do exactly that until I was forced to replace the PSU when it abruptly burned out. 300w nowadays is nothing.

Make sure the connector cables are what you need. I usually go for the PSUs with detachable ones to reduce clutter.

i think i just ran into some trubble, im not sure that the connectors are the same... have the connectors changed since 2009?

For some components maybe....best ask on a hardware forum. If the maker of your machine is still around ask them for recommendations.

I did that once and traced it back to the sofa where my wife was sitting.

Don't cheap out on a PSU or you'll just end up having more trouble. Cheap PSUs aren't worth the money you spend on them a lot of the time.

I just remembered that I had some problems with that newer PSU's connectors and had to buy some adapters to get everything plugged in again. They don't make things easy do they? Sigh.

Praying I never have to go through that again with my current machine.

P.S. The previous poster's advice to not be cheap on buying a PSU is sound advice, I would heed it.

Regarding his wife - well I wont comment.

Chances are some components have started their natural failing and need replacement (things like capacitors can last 2 years or 20 years, depends on so many factors). Regarding a fix, unless one has good experience in electronic work there is a risk of electrocution, fire, damage to other components etc. You'll probably need a professional to do the job but it surely won't be worth the money compared to the price of a new PSU. Get a replacement, if possible bring your PSU to a computer service shop to be sure to get a 100% compatible replacement.

PSU's and hard drives are often the first things to fail.

Well atleast you get more than 20$/month for your job or whatever your getting money from i hope, If i atleast had a better economy i wouldt care as much in changing hardrive, psu and os, but right now i have to save money for 1,5 year to afford it so im pretty much in a bad situation

I'm living on a pension that never gets bigger, but my rent and other costs do, so things are tight here too, believe me. If my current computer died I'd probably simply give up on the Internet altogether.

yeah... stuffs hard...
Well i hope that your computer will live for a while then, luckely i had like a charity thing where i sold enough stuff so i could get a new computer, otherwise my desktop would be dead now, my desktop is like a uptime countdown, it has like a mounths uptime left until the psu blows or something...

I hope it turns out OK for you too
