Something in my system possibly damages PSUs.

[Konski]

Hello, first time posting on this forum and I've absolutely no idea if this thread is in the right category or not, so I'm sorry if it isn't.

Anyhow I've ran into quite a weird problem in the past week and I tried to search the internet but couldn't find anyone with the same type of issue. Let's start; I built my first system a little over a week ago. All seemed to go well etc. got everything up in their place and I took my time to make sure everything was set up correctly. I got the system running, have had no problems with anything considering software/booting/gaming. However after I put together the masterpiece and had it running for a couple of hours I started picking up a clicking noise coming from the PSU area. It was clearly audible, a little bit like a sound of a loose contact. I proceeded to turn of the PC and the sound was still there, only a little more quiet. So I automatically assumed that the PSU (Corsair VS650) was damaged in someway. I made an RMA and the store where I bought the unit tested the piece and told me that they could reproduce the noise. So I got a new one.

This is where it gets weird. The new PSU did the exact same thing. I brought it back too and they gave me my money back and I got a replacement EVGA supernova g2 750w. I made sure everything was the way they are supposed to be and connected this one in. It does the same sound again. With all these units it took sometime for them to start emitting the noise, maybe a couple of hours or so and the sound is electric. I have it connected into a power board or whatever they are called, like an extension cable with multiple plug sockets and I have tested replacing it, no success. At this point I'm suspecting the motherboard. Clearly there must be something wrong since the people at the shop could reproduce the sound so something must've happened to it. And it sure wasn't there the first time I booted up.

So, my questions are: Is there a risk of frying my whole system if I keep using it in this state? Does my system damage these units? MoBo? CPU? GPU? The system is working really well except for this problem. I really don't want to turn it on because of the possible risk. I'm going to measure the voltages from the wall socket to see if there is any spiking and post if I get some new info. Tho mains power problem is highly unlikely because everything else in the apartment is working great. Could this somehow be software related? Any suggestion where I could start here? Here are my specs:

Fractal design R4
Asus Z170-P
Intel core i5-6500
Asus GTX 1060 6gb
8GB HyperX Fury RAM
Kingston 120gb SSD
Seagate 1TB HDD
EVGA Supernova G2 750W

well if it was in fact the motherboard the psu(especially the evga gold) should trip the pc into a forced shut down. not make sounds, this place you are buying them from are they selling them new or pre used/ refurbished?

 

[superninja12]

rattling noise from a psu? are you sure its no case fan?

 

[Codrru]

most likely it is coil whine. easier to google that term for the full description, but assuming it is not and the power is regular i would say bad bearing. most likely if it is not refurbished then the store that you bought it at got a roughly handled shipment. honestly though i wouldnt be too concerned, monitor voltage in bios to see if there are any spikes otherwise a sound is sometimes just that.

The store has a very good reputation and all parts are new, they come in sealed packages. Im sure since they could produce the sound with passive components at the store. And if it was a case fan, it would stop when I turn it off but the sound is still audible. Yeh, Im gonna try and see if the voltages are off from BIOS. If it was another bad component I would assume it had some other symptoms but it doesnt.

hmm, well only thing i can think of is coil whine or bad bearing so ill bow out.

Could this have something to do with power saving features of the CPU ?

MERGED QUESTION
Question from Konski : "3 new PSUs, all produce a clicking noise."

I posted a thread about this earlier but had no luck with answers so heres another one.

The problem is that ive been through 3 PSUs on my new system because they all started producing a clicking sound after a couple of hours. The sound was constant and there even when the system is turned off. Other than that the computer works great and has had no issues with anything from the first boot forward. The first 2 were corsair vs650, I filed an RMA and the shop could reproduce the sound on their test setup so theres clearly something wrong. The latest one was evga supernova g2 750w and it did the same thing. And no it isnt the fans. It also doesnt sound like coil whine. Any thoughts?

If its happened with 3 power supplies then it is being caused by something else in the system

Yeh, that is one option however, everything is working fine with the system. It might be the motherboard? I was wondering if it could be a mains power issue since Ive recently moved to another apartment. And my old PC made a similiar thing now that I come to think of it..

This would be my guess as well.

What could it be? Fans dont spin when the system is offline do that kinda eliminates it. Only the motherboard gets the continuous 5V from the PSU when PC turned off, am I right?

The only question here is that could a faulty motherboard or a grounding issue cause these effects? Cause if this isnt the case, the only cause would be the power coming out the wall outlet...
