G'day,

I seem to have a problem with my PSU. It making some sort of buzzing sound. The problem started a week ago and I didn't pay too much attention as it went away when I rebooted. It only got worse in the last few days now the there is a constant buzzing sound.

The sound is definitely coming from the power supply and sometimes change in tone. I could be mistaken but the fan sounds fine, the buzzing is actually coming from something inside.

I use a Pentium 4 the old single core type. The PSU runs 400W with the following specs +3.3V@14A +5V@25A +12V@12A. I went overkill in fans so the highest temp inside is 34*C if SpeedFan could be trusted so overheating might not be the problem. It has only been used for about 8 months so either I got a fault power supply or it is a dodgy brand (Brand name is "omni"). If you need any more information please let me know I'm not sure what else is needed here.

So does anyone have any suggestions? I have already scoured google for solutions and it looks like I might need to get a new power supply soon. The buzzing is really giving me a headache
