Electrical popping sound

[Azureworld]

Today I found out that some piece of hardware was making a popping sound. I found out right now that it was my desktop plug that was connected to my surge protector. Whenever I turn my PC on, there would be electrical popping sounds coming from the plug. I just build this computer 3 months ago and it's been working marvelously, but not anymore. Could it be my PSU, I have a corsair CX 600, or could it be my surge protector. The sound goes away when I turn off the computer, so I suspect its the PC. Could it be coil whine? I'm not sure what coil-whine or arching sounds like so I'm not sure what the problem is.

Did you try to plug your desktop into another plug, like one on the wall?

 

[Azureworld]

Yes I have, I've also used another plug.

Alright, next try another cable between your psu and the wall, as surprisingly that can actually be the problem. You may have some laying around, or you can find one powering a fat ps3, tv/monitor, etc. If it still makes the sound, your psu is probably shorted out inside. Is it very loud? It could be coil whine I guess. If its loud, you should replace your psu before it causes potential damage to sensitive components. Knowing Corsair, they will do their best to set you up with a new one should this be the case, so don't worry.

Yeah I tried another plug and it still happens. The computer still boots up found but the sound is worrisome

 

[Darth415]

If its pretty loud, you should replace your psu, because it could eventually break something else. I've heard some noisy coil whine, but it shouldn't be AWFULLY loud.

Its not awfully loud, if I kneel down next to my computer I can hear it, or if it's really quiet in my room. I didn't notice it until last night when I went to unplug my ethernet cord from my desktop.

Well, if its not that loud it is probably fine, could even be a fan. My friends GPU makes some strange noises as you stress it, some I could even hear through my headset!
