My bench power supply blew up with a loud "POP". Its time to try and fix it.
This power supply came from my first desktop pc which I purchased from my primary school as a child, before I later converted it into a bench power supply for powering and testing electronics. So it has had over 16 years of use, so lets try and make it last another 16...

  • 1:18 "One is bulging and the other one has completely blown its top off" this describes my drive on the motor way; bulging is to a morons ego and then me blowing my lid off

  • This looks like a yumcha power supply, tbh it belongs in the bin.

  • What's strange that he made this power supply when he was 12, and I'm now making an adjustable power supply with current limiting function. Also I have maximum experience with electronics, and I already repaired 5 electronic devices. And I'm 13! Soon I'll try to fix my old Dell flat screen display, it has a weird reddish tinge, and it shuts down after ~ 2 minutes.

  • so you basically didnt change anything else? the cables and everything is the same? if so then the blowing wont effect any other parts of the pc hopefully, also the close ones.

    • I have been reparing ATX PSUs as part time job for two years now, and this is a sizeable pile of potential ewaste. Also people will get better units in comparison of the fake garbage that they are selling today. A Delta, AcBell, Astek, Bestek, Liteon PSU is a testament of quality and with little money no other power supply will be needed. The new ones are far more complicated, more prone to failures, more expensive to repair, and will meet the landfill sooner. all the 80plus "certified" PSUs when not properly imlemented. HP PSU from 5 years ago, is High efficiency, Infineon Mosfets. Equivalent power Thermaltake ... "Magnachip" mosfets. I would recap the HP one no doubt. Lass landfill and more quality

  • U can short the caps with a big resistor.

    Gunnar SandströmGunnar SandströmÅr sedan
  • Nice video but a few flaws. Mainly that no. You dont have to wait a week or more for the caps to discharge. A few houers will work as the esr of the cap will discharge it. Most power supplys also have discharge resistors in them to drain the caps. While yes they can hold a charge. No in most cases they will not hold a charge for motable weeks. 2 you forgot to put the plastic seperator back in. Its there to keep the bord from shorting to the case.

  • can i fix a power supply with 2 blown mosfet? (high voltage side) or is there something else that got damaged ass well because the mosfets blew up. its a 1200w so don't want to throw it away. it failed because of a dead fan.

  • Funny story, so everyone always jokes that I break everything. Well one day, I was going to turn on my brother's PC (he asked me to) and then I walked away. I was talking to my dad (he was also in the room) when suddenly, we here a loud balloon POP. I noticed my brother's PC was off. I tried to turn it back on, but to no avail. My dad (he works well with hardware) took it off of the desk and put it on his working desk, he did a test on his power supply, and it didn't work. He then told me the capacitor failed and that he had to replace the power supply. Thankfully he had a spare.

    • Back in the day, the other port was used for powering your monitor. Saved an outlet. In some cases I think it would actually cut the power to the monitor when the computer was off. Not sure about the specifics of this particular power supply.

Now my phone turns on and off all the time every 3 minutes. I gave my phone to an repair shop and they changed batteries, found errors (kortsluiting in Dutch) and is now replacing E-chips and says it’s still not working. What can be done so it works? Or what’s the big problem?

DONE, it will look like new. I have done this about 20 times with power supplies and it has worked 100% of the time. It also works with mother boards.

    • Small electronics are much harder to work on because the size and the fact that many components are rolled into one SMD package with virtually no info for them online. This makes repairing them impossible and replacing them very difficult.

  • Those capacitors will usually discharge in a few minutes. If you leave the PSU for half an hour it should be ok, you don't have to wait a week. Also, don't short them with a screwdriver, use a power resistor.

    Bogdan SerbanBogdan SerbanÅr sedan
