PSU HOWTO clean dust from PSU?

I have a good but dusty PSU I want to reuse for a new build. Am afraid of playing with real electricity/capacitors (12V is easy). What is the best way to clean a PSU?

Thanks in advance.

 

A can of air duster

 

Unscrew it, take the outer case of and go at it with compressed air.

 

I recently sorted my daughters psu out as it was absolutely packed full of dust(I should of photographed it really).

I turned the psu off and unplugged it, hit the pc power button a few times with the hope to discharge it and then left it for a few hours. I then removed it from the case and took the top casing off the psu.

Using a combination of a compressed air can and my vacuum cleaner proceed to remove pretty much every speck of dust from it and it still works perfetly. I also used a new medium sized paint brush on the outside as the psu has a meshed design.

 

You don't really need to unscrew them unless there filthy just go over the vents with a can of air

 

Mine had rather large chunks of compacted dust that wasn't going to come out otherwise, plus I reckon I had to use a lot less compressed air from the can by doing so.

 

This is what I use. It will very quickly pay for itself when compared with the cost of canned air.

Keep the fan from spinning if you use compressed air. If it spins faster than designed, it can be damaged.

 

Yup. Only a quid from poundland as well

 

Thanks all. Very useful information.

 

Just be careful taking the case off a PSU, it's possible to get a nasty shock. You'll probably be ok (I've never got shocked), but be careful ok!

 

The main thing to keep in mind is that the heat sinks often have a charge, so if you end up opening the PSU (for cleaning or what ever reason) avoid the heatsinks, or just use an insulated screw driver to connect the heatsinks to the casing.

 

nasty/deadly from memory

 

Just wear a full rubber body suit and you will be fine, might take some eplaining to the misus though.

 

Hmm, you chaps are not filling me with hope here... What happened to keep calm and carry on? What could possibly go wrong here?

Surely, there must be a way to 'bleed' out the charge? Like earth the thing and wait a couple days... Otherwise, it is just blow some air on the dust from far away.

 

Giotto's Rocket Air blower is what I use, a nice alternative using free hand energy, so zero running costs.

 

I wouldn't want to take a PSU apart (Mostly cause of warranty) but also because of the harm I could possibly cause myself. I would just advise Compressed air thru the vents.

 

Hmm, not heard of one of them before, sounds good. How good at clearing dust is it compared to a canned air duster in a computer?
At less than twice the price of a single large can of air it could be much cheaper.
