The amazing whistling power supply

My ANTEC power supply whisles when my computer is off, is it a ticking timebomb?

No, that is the CPU at idle, whistling and oogling at the porn left in its cache after hours of course!

The flux capacitor? Like Back To The Future? Careful dude you could travel back in time and see your own Mom hitting on you. Gross.

Anyways to make sure it is the PSU do this.

1. Remove all power connection from the PSU and have just the PSU connected to the power.

2. Now turn off the PSU switch if it has one or uplug from the power source.

3. Get a wire and cut ends to expose contacts and stick it on the motherboards main power cable. Connect the green wire ( there should be only one) and black wire (ground wire which are many) any black wire.

4. Now flip on the switch or plug the power and the PSU should power on even not connected or loaded.

5. Do not run PSU without load for a long period of time so just let it run for 3 seconds then power it off by switching or upluging.

6. If it is the PSU then it should whistle and what causes it should be some reasons.

Bad fan maybe like worn bearing(s)?

Well, it could be the main 12v converter and whatever it is, it's not a good sign and maybe your psu is dying.

I am making too much out of this already, I am pretty sure it's nothing to worry about, a little electronic buz won't hurt.

it doesnt have to mean the psu is dying, most of the parts in electronics vibrate, when current flows trough them and sometimes in computer monitors and psus the components are allowed to vibrate at just the right freqvenzy which creates a high pitched noise it can be low pitched sometimes, but that means a more violent shaking is going on since it has to shake that far from side to side to create low pitched noise. you basically cant do much about it. unless you open up the psu and run the psu up in whatever mode it makes the most sound in. then take a screwdrive and use the plastic end to gently put on the different components and when it stops viola! theres your problem. then you gotta find a suitable mass in which to unite this componente to some nearby ones for stability which stops it from being able to vibra thus creating no noise, this mass should be somewhat soft rubbery like and had better not lead current might wanna check so that it doesnt eat the plastic casing of some of the components. this is the only home made solution to this problem. iw opend up my psu and there was already some of this mass in it to stop buzzing noises

but yes the buzzing is potentially dangerous later on, since it defently will weaken the soldering points and ultimately break it, so that at most times it wont make contact. it could also be that a soldering point is broken in the psu which allows some component to vibrate. but then youd have the psu shut off now and then espesially when its cold. this is one of those "characteristics" a psu will have and im doubtful that they would replace it, in sucha case i deffinetly think you should open it up and have it running openly then shut pc off and see what components make noises. after that find a solution which stops them in the long term.
