This review is from: Seasonic X-750 Full module 750W ATX12V Power Supply Unit - Gold (Personal Computers)
These PSUs seem to emit a chattering sound. The first was so bad that I could hear it inside an open fronted/backed cabinet and under another desk from four feet away and have had it replaced as it was driving me mad (hats off to Amazon customer service for the quick turn around). The second still does it but it is a lot quieter. The one thing I can say is that I have the fan switched on and it is silent. I had always thought that Seasonic were the very best in PC PSUs but this experience has led me to doubt that.
