So I just built a new system, all running fine apart from the PSU has a whine, even after shutdown
The whine stops when I disconnect the upper half of the 24pin atx cable.

I have an EMI problem too when connecting my headset to the on-board sound card or my front case audio connector. I have to use my headsets USB adaptor/soundcard to get round it!

Faulty ax860i?
 
Corsair sent me a replacement and its doing the exact same thing. The new PSU is making the same high pitched tone even after the pc has been shut down.

I tried turning the PSU upside-down so the fans intake is coming from underneath the case to see if it helped with the EMI problem which it has, (I only hear it every so often now for a thew seconds) But now the tone is louder coming from the case as its coming through the bottom dust filter.

I really dont know what to do now other than replace it with a different model
 
I will be losing money if they dont refund both the psu's. Now im stuck with a replacement PSU which does the exact same thing. Now I just want to send this back aswel and get a full refund so i can buy a different branded psu.
 
Its pretty bloody irritating though! I just spent over a grand on this new build so I want it to be perfect. Coil whine and EMI problems annoy me but I guess its something im going to have to put up with for the time being. Thanks for your help :(:(:(
 
I have had a nice person reply to my ticket which I asked for a full refund, she said she will contact me soon after its authorised

Question now is what PSU should I get to replace it, which has a good reputation for no coil whine
