New Build - Coil Whine noise - Cannot pin point the component

Its funny how a platinum expensive psu causes issues.

I have same issue in another thread posted with a HX1000 bought from elsewhere and started the RMA process with them, although I started to think I should have gone straight to Corsair instead. Doing a few more tests tonight and I will pack it to be sent sigh.

28 days they said argh! Also they said that coil whine is not considered a fault and might just come back without any change.. Said also high powered psu's are prone to whine because they get more power in. Makes sense in my head but not sure if this guy was trying to just put me off from sending the psu back.

My bronze enermax 625w psu doesn't have any whine but the brandspanking new Corsair is high pitched annoying in gaming. Funnily enough when crossfire kicks in and the nuclear reactor is turned on (2x vega 56) there is no coil whine, I think the whine is there when the fan is off on the psu. Mind you I didn't even dare to try and run crossfire with the 2 vegas on the old psu.

Good luck OP
 
I had a loud coil whine for about 1 week and then it disappeared. The fact is that you will most certainly get some level of coil whine with new hardware but it should go away after some long hard gaming sessions. If you get more coil whine with the new psu then just work it for a week before looking to rma it.
 
Had coil whine from my hx850i on one of my 980s. Had it again on my 1080 for quite a while. Once I'd been running it overclocked the noise did indeed stop completely.
