Air dusting a PSU

I've got a Silverstone 650W power supply that's extremely loud. I also notice that its internals are covered in a layer of dust. How would I go about opening and dusting off the components?

Specifically, how would I safely do this?
 
If you don't care about your warranty, go ahead and start unscrewing stuff. Otherwise leave it as-is use the canned air from a decent distance.

I don't think it has a warranty, as I pulled it from an Alienware. Unfortunately, I don't think it's possible to clean the dust from this without removing the casing. Although, the stick appears to be applied in such a way that removing the casing wouldn't touch it.

How would I go about doing this safely?
 
If you dust want a layer of dust off you can just spray air into the back of the PSU and it should come out somewhere, if you want to get into all the small areas and corners then ya you need to unscrew the PSU and do it like that from a safe distance.
 
Maybe it's just me but I have never opened a PSU to clean it. Using a can of compressed air with the little tube attached has always worked for me.

However you said the PSU is loud so if you want to quiet it down you will probably need to replace the fans. This is the only reason I would bother opening it up.

Oh an as for safety, if you open it up don't go poking around with metal tools. Also if you are going to replace the fans be very careful when unplugging the connection assuming they aren't soldered directly to the board.
 
why not just use an air compressor and spray air through the inside of the PSU? I've never seen a need to take apart a PSU to clean it out. An air compressor will also have a lot more force than a can of dust off, and wont slow down when the can gets cold from a long duration spray.
 
Canned air should be enough. An air compressor might have you running out to the store for a new PSU. :D
 
we do it where I work everyday. At about 80 PSI too. Haven't broken any yet and we've been doing for 2 years now. If 80 PSI were enough to blow say a transistor off a MB, its probably already broken.
 
air compressor with a water filter and oil trap yes! air compressor without no don't go there.
 
Just don't point the air compressor directly at the fan(s) unless you want to kill the bearings :p
