OCZ PSU Slight Buzzing noise

[djrobbiepaul]

Hi Guys,

Today i went to plug in a firewire cable into the back of my pc and when my head was next to my pc i noticed that my psu is making a slight buzzing noise.

This same buzzing noise is also heard when the computer is off but switched on at the mains.

Now i have never had my head that close to my pc so it could have been doing it from new. But could this be faulty or is it normal for a slight buzzing noise from psu's.

The psu is a ocz stealth xtreme 500w and is still in warranty.

Yes the buzz is only very slight, the pc tower is at my feet on my desk and when im sat on my chair i cant hear it so like i say i can only hear it very slightly when my ear is next to the case.

My monitor also makes a very slight buzzing noise when its in standby mode so i think you could be right about the noise being generated when a device converts the voltage to DC.

Thanks for the quick response it was just for peace of mind to be honest and just wanted some input from other OCZ users.
