  • Speakers/PSU humming while gaming

    Seems like I've got a little issue with my PSU.

    When I'm playing certain games, my speakers seem to have a rather noticeable hum, and depending on what's on the screen, the hum will be high-pitched or really low. It seems variable. If I'm playing Nascar 15, there's a very low frequency throughout the speakers. If I'm playing Fifa 15, it's almost a squeal that's coming from the PSU itself.

    Any way to fix this? Is it a sign of a failing PSU? Do I get out the compressed air can? It's irritating to the nth degree.

    It sounds like the PSU is running low on down force. Tack on a spoiler / park bench to the back of the case and maybe add a k&n sticker on the side, for good luck.

    If that doesn't do it... A new euro style front clip should really fix the problem. Check with your warranty provider first, however.

      In all seriousness, it sounds like your flux capacitor.

        I am confused... explain to me why the PSU has anything to do with the speakers Rich? It doesnt power them unless they are running off of USB power. So your sound has nothing to do with the PSU. Now your motherboard on the other hand and the onboard sound chip-set could be a problem if you use onboard sound. Power would still be irrelevant. You either have stable power or dont. But the sound card onboard can go bad.

        What version of motherboard do you have? And what kind of speakers?

          And what year is that capacitor?

            Probably made in '85.

                I couldn't tell you why, but identical noises are coming from both the PSU and the speakers at the same time.

                It's a Gigabyte GA-H110M.

                  Is this a new build (assuming it is based on mobo)? Did it just start occurring or has it been this way since you built it? What happens if you listen to audio through a headset plugged into the front audio header? Motherboard or dedicated sound card? How is your ground? Are you sure you properly installed the mobo? Is your mic muted? What brand is the PSU?

                  So many questions.

                    Is the positive terminal connection solid?

                      Okay, so I figured after switching home theater units and trying different aux cables, it's most likely a driver issue but i can't seem to know what exactly to do. Video shows what I'm dealing with.

                        Alright I watched your video. I am not saying it cant be the driver, it surely could. But it looks like you are doing a good bit of cable conversion from one piece of equipment to the next.

                        Stereo from the PC to analog RCA on IDK what that box is. What ever that gray box is down to another amplifier it looks like. What is that connection with?

                        It really could be that the onboard sound cant handle the signal attenuation you are pushing it across.

                        Can you lay out the flow of the data from the PC to the speakers.... equipment name and model, cable type to and from.

                          It's just an Aux/RCA cable running from the headphone jack into the home theater receiver and its speakers. The rest is all connected to that receiver.

                          It's a Panasonic SA-HT700.
