850AX Buzzing Noise


Recommended Posts



Just installed my AX850 into my computer and I can hear a buzzing noise which appears to be coming from the PSU. I can just hear it from my desk while the PC is on the floor and it is getting quite annoying and I can't seem to figure out why it is doing this. I am fairly worried about it as I do not want my PSU to blow up and take my system with it, is this sound normal or should I be requesting an RMA? I have also tried to disable power saving features in the bios and it appeared to have no effect.


Motherboard: P8z68 Gen 3

PSU: AX850

CPU: i5 2500k


Any help is very much appreciated,


Thanks, Alex.

There is a sticky at the top of this thread about noisy PSU's please check that\ post and try some of the things suggested.

If you cannot resolve the issue we can try and RMA but many times issues like this can a cause external to the PSU.
