eternity Posted October 17, 2008 Share Posted October 17, 2008 Hello. I bought a HX620 power supply, and while its really quiet it makes a high pitched electrical whine noise in certain situations which is really annoying. Couple of examples. - When viewing certain webpages, when you scroll the mouse it makes this sound. - When playing a game. On the menu option screen (Half-Life 2 CS) it makes a constant high pitched sound. - In Windows Vista when you select Windows Dreamscene as a background (moving image) it also makes the whine sound. These just some of the examples, none of them should tax the PSU in any way. I have checked all my cables and reseated the graphics card. The noise is definitely coming from the rear of the PSU, by the vent at the back. I've tried a friend's Enermax 625w Modu+ PSU and it doesn't have the same problem. I'm stuck at what could be causing this. Thanks for any help. Link to comment Share on other sites More sharing options...
