I bought a PSU recently from one of the makes who are well-known for making silent PSU's in the past. However, this PSU was quite audible and had an electrical hum.
I sent my Return request and got an email back asking me if the item is faulty or if I just want to return it back. I replied that I just want to return it and since then , I have not heard back! I sent another email and still no reply!
Meanwhile, it's been a a week now.
