Fabian H. Posted June 19, 2017 Share Posted June 19, 2017 Hello guys, I recently bought the RM850i as my new power supply. It is constantly giving of some kind of sound, which gets louder when i increase the load. I include a video where the CPU only is stress tested. I recorded the video with my phone and sadly, since smartphones were not made to pick up high pitched noise, it is rather hard to pick up in the video. (EDIT: See post (4) below for slightly better quality.) [ame] [/ame] Is this coil whine, or something else? Should i be worried? I found this other thread and to me his noise sounds about the same:http://forum.corsair.com/v2/showthread.php?t=155213 Thanks in advance, Fabian Link to comment Share on other sites More sharing options...
Corsair Blake Posted June 20, 2017 Share Posted June 20, 2017 Sounds like it's coming from the video card. I used to have this issue with my older 7970 card. Once I replaced it with a 780, it went away. Try placing your ear next to your card and see if it gets louder. Link to comment Share on other sites More sharing options...
Fabian H. Posted June 21, 2017 Author Share Posted June 21, 2017 Thanks for the reply, but as i stated above the graphics cards was under zero load when recording this video. The graphics card does make noise too when under load.. but it sounds different. The sound i am refering to definitely comes from the PSU and sounds a bit like birds chirping, or basically like electricity. Today or tomorrow i will try and upload a better video. Sadly the noise is nearly inaudible in the video i uploaded. I'll try to get a better recording device. Link to comment Share on other sites More sharing options...
Fabian H. Posted June 22, 2017 Author Share Posted June 22, 2017 I uploaded two new videos and added additional information to be more clear about the sound i'm hearing. I'd like to mention that, since both videos were again recorded with my phone, the noise is more clear and "louder" or higher pitched when actually hearing it. You might want to turn up the volume a bit higher than usual when watching the videos. In the first video, i put the entire system at 100% by stressing cpu and graphics card. The psu is pulling ~425 watts from the wall here: [ame] [/ame] The noise i am refering to should be relatively easy to notice in this video. To me it sounds a bit like chirping or electricity. In the second video only the cpu is stressed, resulting in the psu pulling ~180 watts from the wall: [ame] [/ame] The noise i am referring to is way fainter in this video, but definitely there. Despite how faint it is in the video(s), when actually being near it, you can hear this noise even when the computer is idling at about 60 watts. About the source of the noise: - In the second video the graphics card was under no load (and made no noises whatsoever), excluding coil whine from the graphics card - With my ear right next to the psu i'm certain that the psu itself is giving off these noises Link to comment Share on other sites More sharing options...
CrysLi Posted September 2, 2017 Share Posted September 2, 2017 I have exact the same Problem with my RM750i. While the noise from the PSU is quite faint, the electronic of my TV is starting to make the same noise wenn the PC is running. The Noise form the TV is much louder then from the PSU. And it does not matter where the two devices are plugged in. I even put the PC in the garden and used the power point from the Shed. But as soon as i power on the PC the PSU and the TV in the house are making this Noise. I replaced the PSU as it is very annoying and i am worried that it will damage my 2500€ TV over the Time ... No such Problems mit PSUs from other manufacturers. Link to comment Share on other sites More sharing options...
Corsair Blake Posted September 5, 2017 Share Posted September 5, 2017 Create a ticket through our support site. Definitely sounds like an issue and an RMA would most likely resolve this. Link to comment Share on other sites More sharing options...
