Very loud PSU noise

    I built my PC in early 2017 and about a year later this loud noise from my PSU started to come up during cold start ups. For the past year, restarting multiple times solved the problem but it would still randomly start making noise every now and then. Now, it makes the noise every time i start it up and I've tried restarting many times but the sound wont go away. I'm planning on replacing the PSU but I would like to know what exactly the problem is that is causing this sound. I have linked a video recording of the noise it makes. My PSU is the Corsair CX500M.


    Any input is much appreciated. Thanks in advance.

    Something is in/rubbing on the fan or the fan is failing. If you can solder, you can replace the fan fairly easily.

    Having said that, unless you are using a Tier 1 power supply, I'd simply replace the power supply (with a Tier 1 model).

    If you still have the receipt you could RMA it, it has a three year warranty. Or you could buy another Tier1 and RMA that one and keep it for a test spare.

    I would go for a new pw supply. The CX series from corsair is fine for what it was designed to do; pw a basic build NOT running a gaming video card. I even use a cx pw supply in my home theater system however I would never think of gaming with that system.
    The above advise from lynx1021 is very good. Get a quality pw supply and RMA your existing one. Having a test pw supply on hand is very useful.
