JayJ93 Posted July 27, 2018 Share Posted July 27, 2018 Hello, my first post here, hopefully somebody will be able to assist however I am doubtful this is an issue that I am able to resolve. Some background; last year I purchased the RM1000i PSU to run my setup which worked well for a number of months until it failed. The failure resulted in the computer shutting off and knocking out my upstairs power. After a few test I concluded the PSU was faulty and sent it back for RMA. I received what appeared to be a brand new one back and it looked pretty pristine so I have no reason to believe it is anything but a new unit however when I plugged it in I noticed it was making a buzzing sound. After a few tests I found it was getting much louder whenever the CPU was under a higher load, presumably because of more power draw, but I could not find a way to stop it. A few hours later I decided to remove the PSU as it was hard to use the PC with the buzzing. To confirm, it is 100% the PSU, the noise stops if I put a different PSU in. I get that some hardware makes noises but given that this was quite expensive and a replacement for one that failed it annoyed me a little so I put it in a box and left it. Now I want to see if it can be fixed. Is this a known issue with the PSU/is there a way to fix it or does it need to be sent back again? Link to comment Share on other sites More sharing options...

You probably got a dud, create a support ticket with us and get the unit replaced. Link to comment Share on other sites More sharing options...
