Here is a short disassembly of a PC power supply.
Since we are dealing with something that provides power to a PC, you MUST remember to discharge the capacitor!
Anyway, you start out the disassembly as usual, by removing all of the visible screws. Note: these screws are held in place tightly and you really should use the most tight fitting bit that you can find.
You might as well cut those stickers shown above, as they will only get in the way.
There is really nothing more to it. You could remove the PCB but that would serve no useful purpose (though I bet you could hide stuff under there…)
Not much there, just opening a few screws.
What would be cool is if there is anything to open/disassemble after this. I tried obviously, but failed
How about how to remove the fan and reuse it in a pc?
its lovely, bet we need more than that. i hope when i am introduce as a member i we do my best to make takeitapart a home sweet home. THANKS GREAT ONE
I have a friend who re-uses the fans in power supply boxes for PC cases. But I refuse to mess with it because of the stored electricity. I know it’s wimpy all I have to do is discharge it but I still leave these and TVs alone.
I don’t reuse the fans, I reuse the PS when the fan fails. I find the fans are always failing before I have to replace them. I believe that most PSs fail when the fan has failed because most people ignore the groaning sound they make before they completely quit. Silence is deadly.

What is the best way to discharge the capacitor?
Haha, I took those apart as a young child all the time without ever discharging them. Damn, that’s sort of scary.
The best way to discharge the capacitor?
Well… I must recommend that you don’t mess with capacitors if you can avoid them, but if you must, see this or google around a bit.
The only two times that I have taken a PSU apart was to replace the fuse, and the other time was to replace the fan which had become noisy.
if you want to make to psu work without the computer get a spare piece put one end in the green cable slot and the other in the black, this will jump start the psu into life as it thinks the motherboard has turned it on or something like that. This is good because you can use the spare red and black cables to run any spare appliances that run on 12v but just pushing in tho cables into the black and red

I am or was useing an ATX powersupply but I think a capacitor shorted in it and other very overly helpful people have pointed out that they agree its probably the powersupply too so I wanted to try that “green to black” hotwireing trick without the supply connected to anything, the only problem is I have a couple of black wires that connect directly to my mobo from a single socket and a secondary jack that is ment to connect to a daughter board, will this even work for me?
I wish I knew about this site when i took apart my power supply and removed the stock fan and installed a higher RPM blue lit fan, it came out good till a couple months later it kept turning off and on because i put eletrical tape and it came off but i fixed it and its been working ever sence
Ive used one of these out of a pentium computer to run a car stereo the radio was a 8.5 watt total 4.5W+4.5W and the power supply I used put out 2.8 amps at 12V Neg Ground and i rigged the part of the radio that always stays on stays on to another supply (for the presets) a lil one and i used this power supply to actually play the radio
er… guys i took my old pc power suply apart (not been used for 1 and a halve years)
i cut the wires took out the fan i did not get a shock why is this???
Yes.. we can use the fan and use it as a chassis fan, i’ve already done that its already 100% working on my desktop, Great cooling.. Helps a lot.. Fans from Power Supplies are only 12Volts
alexander remember that charges are only held for a certain ammount of time, it must have lost its charge after a year of no use
be care full some hold there charge for a few hours some for up to 6 months dont take your chankes as ac damn hurts but dc kills and burns (ac can still very easely kill ) and it will be dc stored in the caps.

put your tongue on the contacts
I dont know much about psu’s except I’ve replaced one’s that have died and so on…. I have 2 that I want to put into my mom’s dell cause, well its cheap and crappy….. but the I/O switch gets in the way when i try to put in one of my spare psu’s into the dell….. cutting the metal to make room is out of question, so i was wondering if there were a way or if its unsafe or what… to alter the psu and maybe take the I/O switch off?
let me rephrase that…. I have 2 spare psu’s and i’d like to use one in the dell, but both have the I/O switch that gets in the way.
There are uncompatent people who would try “put your tongue on the contacts”. NEVER DO IT! I think discharging with a 100W light bulb is the best way. I never repair pc psus because a new one is very cheap. If a repaired psu go wrong again it can destroy the whole pc. Would worth it?
