Is it safe to use an air compressor to blow dust out of a computer?

[GhOsT1321]

My father has an old air compressor, assuming I can find the hose and attachment, I would like to use this to dust out my computer case. The compressor is rated at 200 PSI, and I am concerned this may be too much to be safely used on computer components.
Is it safe to use this, or any air compressor, to blow dust out of a computer?

I use a air compressor on my PC, but I turn the air pressure way down, to 10 or 20 psi max. You need to be careful because you can blow the jumpers off the mobo.

Yep... I use one as well so I would say it's safe to use. With care of course.

I use a pretty high pressure one on my computer. Hasn't failed me yet

I use a small compressor so it starts as high as 60PSI and drops as it's used but I have had no trouble yet. Just watch that you don't blow off jumpers or connections. Obviously, the higher the pressure add more distance between the nozzle and the parts.
