    Is my PSU bad?

    My XFX 650W XXX PSU was bought a few months ago, and I never really noticed any unusual sounds, however whilst rejiggering a few things inside my case I noticed the noise coming from it wasn't "Clean" so to speak.

    I've had someone tell me it's a bad fan bearing, which could go some way to explain why the PSU fan ramps up like crazy under load when things are getting hot.

    Thoughts?

    Perhaps contact the place of purchase (assuming here) and see what they say. I'd ring up though as it's quicker.

    True, but during gaming the psu is the loudest part of the pc.

    Hi guys, update here.

    PSU fan blocked

    Psu fan unblocked

    I really doubt a PSU fan should be making that much noise. Time to rma?

Note: Do NOT push something far into it, just enough to stop the fan from spinning, ideally at start up when the fan isn't moving to begin with.

    THIS!

    Insert pen, turn on PC, is noise gone?

    can't imagine which other part of the PSU might make that noise, sure as hell isn't like any coil whine i've heard, and too high a frequency to be transformer related, and too uniform to be capacitor related, similar thoughts to coil whine, weakest part of some seasonic units is the fan, they'd be better off using bequiet silent wings

    LOL yes, a pen would be my choice too, but you just never know with people these days !!

    Don't be silly, something like a pen would be my first choice. Something that will not conduct electricity!

    i'm 99% certain pain involving a finger is likely to be the result of this test

    It's merely to determine whether it's the fan or another part of the PSU making that noise.

    I'm 99% confident that it is the fan, though.

    I think i know where he's going with this, but i'm not sure of the methodology in the testing

    yup, sounds like a bearing, only other thing i've heard sound like that has been a sticker on a fan lifting and catching the air, before then catcing on the grill causing that noise, how does it sound/behave when it powers down ?
