What is that Buzz Sound on the back of my power supply?

Question

Hello, for some strange reason, my power supply is making this Weird buzz sound, its getting pretty irritating, i got my 450 watt power supply from best buy, its a thermaltake TR2 Cable Management 450W. that's what it said on the side of the box, at first the buzz sound didn't happen, now it just started, and when i turn it off, and turn my computer on back, same problem, i checked inside my computer to make sure any wires or anything is touching the power supply, and i made sure the fans didn't touch it, and yet it still makes that Buzz Sound for some odd reason, lol!

here is the pic of my Case: http://www.overclockersclub.com/siteimages/articles/verrev770/5_thumb.jpg

Hard drive: http://ecompshop.co.za/catalog/images/seagate-barracuda-hard-drive.jpg

So i know the sound is NOT coming from the Motherboard, or Hard drive, its coming from the back of the Computer.....

is it making that sound because i am using the computer frequently? any advice to stop making that Buzz sound??

best answer gets 10 points.

Thanks!!!

Answer 1

Sounds like the fan may be loose and it's vibrating. Maybe see if you can s***w it in tighter.

Answer 2

Anytime I hear something buzzing , I always think it's my brains. And , if it's not my brains, it could be an insect .  But, we're talking about a power supply here aren't we so, after you have retried all of the  other suggestions, perhaps it is some dust particles that have gotten inside the connection some where.  

Answer 3

Could be the power supply - the transformer inside is buzzing.

Could also be the fan on the microprocessor.  Could be the hard disk drive being accessed.

Use a sound stick - wooden stick and put one end to your ear and touch the different parts of your computer to amplify the sound - mechanics do it all the time in cars.
