How do I clean out my PSU? I am sure that it is pretty dirty and fully of dust, etc. I can clean the part where the fan is without too much trouble. However, doing it that way seems to blow stuff into rather than out of the PSU. I mostly am using a can of compressed air or a blower.
 
Looking at videos on YouTube seems to turn up too many wrong ways to do it... And I'd rather not take the PSU apart if I don't have to.
 
Hoping some of you might have some advice or tips that you use. Thanks.

Un-Plug the Power Supply Cable BEFORE you Blow it out.
Blow it out from the Fan Side Out to the Rear.
You can use a Plastic Straw to Hold the Fan Blade from moving.
 
"take the PSU apart" Can Void a Warranty.
 
Blowing air into the Power Supply with it Powered On can cause a Short Inside the Power Supply if it is really dirty inside.

Also keep in mind you should never open up a PSU for any reason. It can hold a charge even if unplugged from the wall that can seriously hurt or kill a person.

Canned air should work very well but I wonder how old the PSU is? Most modern ones only really turn the blades when it’s running hot to cool it down. Older PSU or ones not using an eco setting will run all the time and get dusty faster.

I must check one day is it my PSU dirty inside. 
I hope it's not because fan didn't worked 95% of time. 
Dust can't enter inside from top. 
Of course I will not open him.

I use this to place on top of my Power Supplies
Silverstone Tek 140mm Ultra Fine Fan Filter with Magnet Cooling FF143B (Black)
It also stops screws from falling inside the Power Supply.

It really depends on the way the fan is facing. If you have it facing up into the case it would get airflow from the case fans and get dusty. If the case has the PSU fan facing down and only turning as needed probably it will only get a fine layer of dust like everything else. Normal maintenance would still be recommend though to deal with any dust.

The PSU is an EVGA SuperNOVA 850 G2 - purchased in early 2017.

I'm surprised how my 1200 P2 is clean after 4 years.
I didn't clean him at all, never.
But fan didn't worked 90% of times.
 

 
This is new version, Antistatic protection, price is same.
It's not only bracelet, DataVac is different.

I use this one, it works great! It come in different colors. It also have a very long cord, 2 speeds and filer on the bottom.

I didn't saw that XPower but I believe DataVac is best such device on market.
Quality is incredible. Only bad thing is loud noise of motor, but I believe it's not possible to build such effective device to be silent.
It's not Asian garbage. 
 

 
In my country cost 170 euro ESD model, newest.
Same as on video.
But if you left dust to collect 5-6 months, you will need to install brush or simply to use cloth at the end.
He is effective and PC will stay clean completely only if you use him every month or 15 days.
 
Worth buying 100%, every cent worth.
There is a 10 different devices with price 10-30$, not effective garbage.
Some of them can't move small pieces of bread from table.
 
Or you can use car compressor, only later you will not find half of capacitors, BIOS chip will be who knows where...etc...

Re: Cleaning out my PSU? 2019/05/02 00:45:34 (permalink)
I like most to clean motherboard with isopropyl or Arctic Cleaner and cotton swabs.
That's most interesting, easy nice, between all parts gently because cotton can't stay on metal parts.
Need at least 20 cotton swabs. Special if you remove and heatsinks, etc than it's even more interesting...
Off course on high end motherboards and graphic cards.
One guy who work in service learned me, never install naked heatsink on PCH chip, only if heatsink have sponge or use 1mm thermal pad to cover whole PCH after cleaning. Never only thermal pads and tight with screw driver from back side only using two fingers and stop immediately when become hard.

I would have thought that opening a PSU is not a problem as long as the PCB isn't removed as well.
I mean, isn't touching the terminals of a high-voltage capacitor the only way to get shocked (and maybe killed) by it?

yes as you said the capacitors hold high current it has to be closed otherwise it will like stun gun to your body

Unless your a certified electrician should you work with electronics that could kill. It's like saying having the safety off of a gun is totally fine as long as you don't pull the trigger. It's best to assume the worst danger and treat it with the respect you would a raccoon and leave it alone instead of trying to poke at it with a stick.  
 
The posts about the electric vacuums are a really good idea since canned air is pretty expensive and the cans don't last as long as you would like. Also they freeze up pretty quickly.

I understand, but since the capacitors' terminals cannot be touched because they are under the PCB which is screwed to the body of the PSU, I wonder how one could receive an electric shock.
But anyway, I have no intention to remove the PSU cover since I own an EVGA G2 which is still under warranty for approx. 7 years.
 
And +1 for the electric blower vs the can.

Because the capacitors are connected to the circuit that has Many points of contact --> Electric shock, including a Fatal one is a very real possibility.  


Additionally - opening the PSU is Not Required to clean it
 
I use a 1.5 gal.  Shop-Vac - use as Blower or Vacuum, by moving where the hose is attached

I totally agree with you, opening the PSU isn't required at all.
And I'm not going to argue over the possibility of being electrocuted or not by just removing the cover.
I've read quite a bit before repairing a PSU that had only one capacitor to be changed. All went well because I knew what not to do.
Anyway, it's a good thing to warn about the lethal dangerousness.
If I remember correctly, it's not the voltage that is lethal but the current, and it doesn't take much to shut down one's heart beat.
 
One recommendation when using a blower would be to do it outside or through an open window.

Using the blower - Outside for sure    ---> someone would only make that mistake one time, if they did it indoors
 
When I blow out my PC radiators it is amazing how much "dust" is still in them even though they are vacuumed regularly & I use filters

Radiators very fast become dirty. 2 months.
Than whole process, case out side, plastic cover over motherboard and GPU, removing fans and clean radiators with brush and later push air through him.

I've seen a few videos on YouTube showing someone using a blower inside.
Sometimes, when one sees someone doing something, one may think: If it's good for them then, it should be good for me too.
So I thought writing a line recommending not to do that was a good thing.
