Okay so I recently built my first computer and I recently noticed that my psu was making a clicking noise. The computer works fine and I'm writing this right now with it. I'm not sure what the clicking noise means. It isn't like a buzzing noise it's just a very faint clicking. I doubt it is dust or anything like that since I've only had it for about a week. If I shut down my computer I still hear the clicking noise coming from the psu. What is this clicking noise?

it could be the fan blade in the psu that are hitting the side of the fan support .if you look at the psu in a dark room do you see any spark inside it ?

I turned off all the lights in complete darkness and hit the power button on the psu and I didn't see any sparks.

I actually don't hear the clicking noise anymore. It's like it comes and goes. I would still like to know what it is though so please reply!

Power supplies are notorious for fans making clicking sounds.

If you have a bottom mounted power supply, try remounting it upside down (if the other side is your case, or an intake port in the bottom of the case.)
