Power Supply Constant ticking noise

I sold my old build whole and now I'm using the two new Default Define R4 fans for intake and I bought a pair of Corsair SP120 High performance fans for my radiator's CPU cooling and another AF140 for my exhaust so no old fans here.

But regardless, It's absolutely not a fan, It's the power supply, I'm 1000000% sure it is.

I've put my ear to it, the sound comes directly from the back of the psu's exhaust area, I've even isolated the PSU out of the build and put my ear to it outside, its definitely the PSU.

I just hope I can find a solution soon.

Thanks for the quick response.

To answer your questions orderly.

1. It's a series of tick noises, going over and over again.
2. I've tried a different socket in my room and also downstairs in the living room and the noise still continues.

3. I don't have access to a UPS but I do have it connected to a good $40 surge protector, not sure how much that would help but at least I make sure my devices are safe from any current spikes.

4. It's definitely not the fan, the HX850's fan is silent and doesn't turn on until it has some decent load on it, I have to Overclock my CPU, GPU and run prime95 and Furmark for the fan on the PSU to even turn on. I was basically staring at the PSU fan not moving at all and the same noise was going on and on in the back, when the fan finally turns on, the sound gets just a little faint but still happening and audible.

5. Yeah, it is pretty strange to get this from multiple PSU's. I got them from the same retailer here in Canada but I tried like 3 different branches, I don't think that large of a batch could be affected.

Like I said before, at the moment, everything works just fine, no problems at all with the computer except for the sound.

One more thing though.

I dont know anything about electrical wiring etc but It could be my house's electrical system. A while ago I got another fridge and put it in my room, I had my old build then and it had no effect on it other than the light dimming whenever the fridges compressor kicked in.

But when I got my new build it had this strange effect that sometimes when the fridge compressor kicked in, my room lights would dim and then weirdly I would hear the windows USB disconnect sound and my keyboard for my computer would disconnect and connect again in like 5 seconds.

I got rid of that fridge and everything seemed to be fine. No more peripheral disconnects but the PSU makes that strange sound even after changing returning the first build and changing PSU's multiple times.

Is there any possibility that my House's Electrical wiring is damaged, all the fridges, microwaves, dryers, irons etc work just fine but do you think that something happened during that period that would specifically ruin the chances of a computer's power supply working well?

I hope I can find a solution to this.

Thanks for your quick reply as well.

Thanks for your quick response.

Yeah, the sound is getting a little more annoying and everything else is perfect. During Gaming I could care less, i can't hear it at all but when II'm browsing the web, doing light tasks or studying (I'm in University at the moment) and I need that utter silence, I can hear it squeaking from my desk, I guess you may be right, the only way to diagnose it would be to just live with it to see if something bad happens, I just hope it never gets to that.
