I have now recently installed 3 of these power supplies in workstations. All of them work perfectly. However, all 3 regularly make a very strange noise (sounds like something is coming from the fan, which is not the case).
I have already read that Corsair PSUs can produce a kind of "beeping" under load (gaming). However, my noise remains permanently when it occurs. What do you advise me to do? Ignoring it is quite difficult, as it is really annoying.

Answer

How long have these power supplies been in use? (Warranty period?)
Have you ever tested with another power supply? (Are the noises also present??)
Either way, I would use a higher quality power supply from the ax or hx series from corsair. (I personally do this and have peace of mind with it).
