hey everyone, my corsair psu Hx 850 started making buzzing noises, I noticed it after a couple of days, but I thought it was normal considering its a new part and all. The buzzing is like the one similar to those lights in office buildings when they need to be changed. The buzzing randomly stops and starts, I believe its only when my fan isn’t spinning that it does this but ill edit my post later. what should I do?
the part is only about 5 months old and I noticed the sound being pretty loud after installing a new gtx 760
I’d be very much inclined to replace it, and if under warranty – exercise that right.
If there is a transformer in the psu it may be the laminations are in effect “rattling/vibrating” at whatever your mains frequency is. Equally you may have large smoothing capacitor a little under stress, not happy. Either way “something” is getting a little warm – which is why (possibly) it stops(?) when the cooling fan operates.
I suggest it would be wise(r) to replace it – whilst under warranty. It does sound a little like all is not well with it, maybe not upto par.
