PSU clicking (not a fan)

post #1 of 3
Thread Starter 
Hey guys,

2 months ago I discovered that my PSU was doing some sort of clicking noise, similar to this: https://www.youtube.com/watch?v=v9SRzzTfK30 but mine was not that fast. So i RMA'd the PSU and recieved a new one which I did not start using until a few days ago (was away for summer) and today I discovered the same sound.

Important things to note:

- Computer is plugged into APC Back-UPS which is plugged into APC Surge Protector which is plugged into a wall socket.

- In the first case (2 months ago) I turned the computer and the PSU off and the sound was still there. I unplugged the PSU from the UPS - the sound dissapeared. I then tried to plug the PSU cord directly into the wall socket and into the UPS again (did not swtich the PSU switch on) and the sound was again in both cases there untill it dissapeared on its own few moments later. After that I removed the PSU from the computer.



- Now, computer I use today is different than 2 months ago - New mobo + cpu and cooler. HDD and GPU remained same and the PSU is the new one from RMA.

- So in the second case (today) - once I switched the computer and PSU off, the sound dissapeared after a few seconds. However that could have been just coincidence, because before I turned the computer off I did some testing and discovered some interesting things:

1. While the computer was on and PSU was making this clicking noise I forced the UPS to switch to battery mode (by turning the surge protector off) and the sound dissapeared.
2. Once I turned the Surge Protector back on and UPS switched to normal mode, the sound appeared again. Then I unplugged the UPS from the Surge Protector (PC running on battery) and I plugged it directly into the wall socket and the sound was there.
3. I turned the computer and the PSU off and the sound dissapeared after a few seconds (as I already said before). Then I switched PSU back on and the sound was NOT there and so far it has not returned (8 hours).

So, I got rid of the surge protector and plugged UPS directly into the wall but it will probably do nothing. I am just testing various scenarios.

What do you guys think? It does not seem to me as some PSU defect, but rather some "dirty power" or something that is causing PSU to do such noises. But why it was not there after I switched PSU back on after turning it off today? Was it just coincidence and this "dirty power" was stopped being supplied at the same time? Or PSU discharged or something and thus stopped making this noise (but then why the sound was not there while running on battery)? I don't know.

I guess it is also important to note that the clicking was occuring during the same time as 2 months ago - around noon.

In case a "dirty power" or something does it, is it dangerous for the PSU?

around noon eh...

wonder if it is dealing with a low voltage situation?

is it hot there right now?

what does the input voltage on the ups say?

No it was pretty cold today (considering it is summer), room temperature 24°C so that should not be a problem (2 months ago around 28°C room temp). I did not manage to read what the voltage was because the software was not installed at that time, but my UPS is set to switch to battery once it goes below 196 volts or above 256 volts and it was not switching so the voltage had to be in that range. Is it possible the PSU would make this noise if the voltage was for example 200V?
