deruberhanyok Posted September 27, 2008 Share Posted September 27, 2008 Hello, I recently got an Asus Xonar D2X PCI Express sound card, which requires a 4-pin "floppy drive" style power connection to function. When I have it installed my power supply (a 520HX) emits a high-pitched whine. This sound carries through the sound card and out to my speakers, though even without the speakers connected I can still hear it coming from the PSU. It happens if the sound card is on a cable with other devices and also if it is the only device on a cable. I'm certain the noise is coming from the PSU and not another component, as I've just gotten the motherboard replaced and found that putting my hand over the fan opening on the bottom of the PSU muffles the sound to the point where I can barely hear it. The thing is, I've never had a problem with any other number of components connected to this power supply. I've had it since January of 2007 and it has been flawless. But then, I've also never had to connect a power cable to a sound card before. :) Which one seems the more likely cause of the problem? Without the sound card installed everything seems fine so I'm leaning towards it as the culprit. Any thoughts? Thanks, Matt Link to comment Share on other sites More sharing options...
