Super Flower FX 550W PSU - Clicking/Buzzing Noise

[dot.rich]

Hello! I usually don't like to bother you guys with PC problems but this one is quite annoying.

When my PC is under load my power supply starts to have this buzzing/clicking noise that is fixed when I push the top and bottom together. My PC is the "Titan Quark" Intel Core i5 i7 Quad Core Mini-ITX Gaming PC. I bought it around mid-August 2015.

The power supply: https://www.overclockers.co.uk/super-flower-fx-550w-80-plus-bronze-power-supply-black-ca-036-sf.html. The "Titan Quark": https://www.overclockers.co.uk/tita...7-quad-core-mini-itx-gaming-pc-fs-093-og.html

I took a video clip of the clicking/buzzing noise:

The PC was turned off, unplugged and the two back case screws on the PSU were reasonably tightened but the problem remains.

Here is a speccy summary when idle:



The case is Corsair Obsidian 250D mITX.

To me that sounds like its a case of fan vibration ...I have the same issue with two of my fans on the top of my case

I had made sure that the fan was secure and also reasonably tightened as well. I don't know what else to do. The problem had shown itself a few months after buying it and I thought it might go away eventually but it hasn't. Also, thank you for replying.

And the clicking ?...that could be the fan in the PSU itself
