Repairing My Power Supply that Blew Up
HTML-код
- Опубликовано: 28 авг 2024
- 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...

The whole video I'm thinking..."If he pulls one of them big ass spiders out of there..."
@Callan DUNDULES I wasn't being mean. Did you SEE that thing?!
I’m Australian and it’s not mean it’s true I’ve seen some big ass spiders
@@Westycj i am not a aussie but i have also seen some big ass spiders here.

a note 7 box in a video about a psu that blew up.... huh
FYI only 10 out of the million Note7s sold actually blew up
@@TheOPtmal why not just say 1 out of 100 thousand lol also it was just a joke
Once I was watching yt on my laptop when suddenly the charging brick decided to give me a firework show out of nowhere.
haha is ur laptop fine
The charging block knew that it was your birthday and decided to give you a fireworks show
It is my birthday today
@@Pocol0c0s happy birthday i nmjust cut me on a screw
good reason that your "charging block" was a generic chinese one (genuine certified charging blocks do no do this)
Power supply: BLUM
Hugh Jeffreys: thanks for the money
hi
@@silentsiIver1 Why hi?
BR!

Hi Hugh,I was just wondering how you learnt to actually repair technology,was it RUclips videos or did you just buy a phone and have a go?Please tell me
Be curious, study, trial and error and pratice
@@melvinharris7859 the 😂😂😂fuck
He started off by taking apart his computer and trying to put it back together as fast as he can that's how he learnt everything
@@meowbauk I tried that with my dog, couldn't figure out the second part
@@melvinharris7859 what the cinnamon toast hell
You use a very big soldering tip for that board
David Badrak lmao
I have a very big soldering tip for that hole
'solder on the soldering iron'
Liquid flux (re: Louis Rossmann) instead of solder?
maybe he dont have liquid
Great job Brother... I've been repairing many of the HP Z series Power Supplies with 18 & 12 Pin non-standard pin outs.. Blown Fets and Diodes are worth swapping as replacements are over $200 USD... DPS-750AB-36
Truly a legend. U repaired a computer parts and not just a phone or modded iphones. The best keep it up bro. Thumbs up to this guy still a legend. 👍💪
You don't need to wait for a whole week for the capacitor to discharge like crt monitors, 15 or 20 minutes is ideal for that. In almost every power supply there is a bleeder resistor hooking parallel with the main cap for safety dischare the remain energy in the capacitor.
You cant be too safe when it comes to high voltage capacitors
@@HughJeffreys Just short them out
@@HughJeffreys Why did you recommend against shorting the caps out?
Some random person: "Hey Hugh, how much pics of Ariana Grande do you have ?" Hugh: "Yes".
6:41 oh crap a bomb in the background
You blew up as psu as you had a note 7 to in the background
Yup,i saw that too!!!
Love your videos so much
Keep up the great work :D
A very unique video, interesting Hugh Jeffreys!
Love your vids, i would love to start doing repairs my self, i recently broke my right wrist, however i was still able to fix my wife's galaxy s7 and my sons old s4. both had broken screens and the batteries were dead(water damage). i dont have tools like u do, but a hair dryer and a cheap precision screw driver set works. i will always support the right to repair.
nice
Anyone notice the Note7 box at 6:44?
Yep
Me
Still using one
Scrubscribe
@ChillyFillyGaming Do you have the Note 7 or Note FE?
Thats very worth it...
Is this the new iPhone I've been hearing about
Probably
You mean note 7??
Now Iphones are blowing up too?
I was wondering if attaching wires to the vents might be blocking airflow and causing some components to run hotter than they would normally.
No this wouldn't cause an issue. Most power supplies are made to stand up to 85 degrees C. In this case the capacitors are rated at least 105C for typically 2000 hours use before that part's life is spent. His little bench supply use is much less strain than what it was originally made to do.
Even if you think you know enough about electricity you should not open a PSU. They are dirt cheap.Please value your life over saving $30
me: I have opened and cleaned every psu that I have once a year
I have a iphone 6 that looks great but mysteriously wont turn on. I brought it to several repair places and none of them know what is wronv with it. It could be an easy fix but if not im sure you could fix it.
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.
4:58 you removed insulation plastic layer but at 5:06 you didn't put it back. it won't cause any damage though as PE (Protective Earth) nodes are separated from other circuitry and a bit higher than the metal case.
You mean plastic insulation layer
With that crappy of a PSU, you are much better off buying a new one.
You can get good ones (which are soooooo much better than that fire hazard in-a-box) for $40.
Sentimental value mate
@@lolcat Then he can just keep it on display or something. It's not worth still using.
He is just repairing it, that's what his channel is all about
Feels refreshing!
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.
Are you nuts
@@sfs2040 no im ceilingfan music xD
I’ve never seen the inside of one of these before, really cool
This guy can repair anything
Your all video are very informative and usefull...Thanks from an Indian..
Cool project
Why is it every time I repair an iPhone, Hugh releases a video?
how many times do you repair your iphone holy fuck 😂
@@AbdAbdAbdAbd idk, I was recently testing an iPhone 6 Plus and he released a video
Well tbh, its not "every" time but most times, its weird
Wait for weeks for discharge the capacitors... Bro, just turn it off, unplug the power cable and press the power button for 10 secs... Belive me, i learn computers and everything in my school.
Or discharge the capacitors with a screwdriver
If you are short on time something I learned i with the psu unplugged and hooked up to a computer hit the power button a few times as the computer detected an attempt to power on and it will pull some of the remaining power.
6:40 well... i think the psu is the least thing you should worry about blowing up !! a note 7 at the back 😆
Tech Yes Loving? On PSU?
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.
Waiting for this video since I have watched it on your Instagram story
Any love to watch your video
Well atleast I know he didn't die from it considering he still uploaded this video
Why would he die?
That is the definition of a power supply that explodes
Great video as always 👍🏻❤️
It ain't the sharpest PSU in the shed
I have replaced the faulty capacitors. Now SMPS turns on but low power on 12v rails. 5v Rail have good power. Also, it is making humming noise but can't figure out exactly from which part.
Then we are going to have Mr. Hugh Jeffreys repairing televisions and computers.
Hi hugh, i know its nothing to do with the video but i have an iphone 7 with a broken home button it says press home to uprgrade i dont know what to do has anybody got tips?
3uTools to skip activation process.
@@DawnVengeanceX how do i do this
@@maxhicks8813 use 3utools
Max Hicks Download 3uTools and install it. Plug your iPhone 7 into the computer and run the program. Once it’s on the main menu, find the skip activation button and you’ll be all good.
Your videos are very informative. I have a suggestion, why don't you open your online store where you sell those repair smartphones.
That's a great idea
How to clean it: spry it with bean green totally cover the whole thing, let sit for 15 to 20 minutes rinse in bath tub with warm water and dry under fan for a few hours. 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.
Can you make a iPhone XR restoration
Hey Hug Jerffy I have a iPhone 7 that doesn't change the put a new screen it work they put a new doc connector it still didn't change she side the problem is with motor bored so can you help me
Zaki Gak i don’t understand you
Didn't know you were also capable of repairing power supplies as well...
I have a 2007 iMac i'mactually worried about the capacitors on this thing, should i check them out
The System Explorer yes
fix on fail. no point messing with them before you need to.
Is this the same power supply out of the "How to make your own personal fan" video?
Very nice I learned something from you today.
How did it exploded?? Did it explode even if you have a AVR or not?
Don't use generic power supply can cause of burn your pc
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.
cool story bro
There any chance we will get a salvage guide in the future?
Could you do a how 2 vid. In repairing phones!
Could you fix an iPhone SE that was dropped in the toilet if I send it to you?
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.
Is there any harm in shorting em once or twice, because to be honest: ''ain't nobody got time for that''.
I always used a screwdriver, I saw it spark, job done. No hassle carrying resistors around...
"don't short them with a screwdriver, use a power resistor."
So they don't get damaged?
Another amazing,interesting video
If you're going to the trouble of repairing it, why replace the capacitor with a used Fuhjyyu?
Is it possible to convert a modern power supply to have a power outlet just like this ancient one?
huge jeffery good RUclips r
Hi! Is there any circuit that I can built just to make an interface between the voltage wall and the ATX supply so that, if aomethig of ATX supply fails, it doesn't burn anything? Or even explote? Greetings!
Hey Hugh can you provide the (buying)links of the parts that you used in video along with the tools.....
This power supply is like a bomb
Wow
I tried the same.. but didn't work. there's apparently a hymn noise coming from the board... the 5v output from the purple wire is the only working section from mine..12v, section has no output
is he saying outside in the shit?😂😂
Have a question for the phone repair master. What battery brand should I buy for my galaxy S7 that I am repairing?
I died after watching this video..
I subscribed to your channel and now I can’t wait for your next video
I got an Blew power supply to but not the same like yours, i want to fix it to but i dont know of you can fix it like you do
I would like to know how many phones you have laying around waiting to be repaired
I've got a recked iPhone X I think it will make for a good video and if you could repair it I would pay for it
I remember when i was just a little kid and my dad punished me and my dad unplugged my pc and he hide It. 3 months later i got my pc back and he plugged in the power supply exploded and a lots of sparks went out of my computer that was a sad day for me, the entire computer died😔
woah
probably moved the voltage switch from 230v too 110v and thus it went bang
@@Samey44 yes yes how do you know?
@@I_killed_that_beard_guy I work in computer repair
@@Samey44 What was the reason for that? High current I think
Will it lose the Touch ID functionality ?
I sure wish you had a 2010 IMAC that wouldn't turn on so I maybe could repair mine . I miss my MAC 😕
Your voice looks similar to Jerry
Scratches @ lvl6 and deeper grooves @7
If my gaming pc’s PSU die, I wouldn’t even think on repairing it, since there are EVGA, Gigabyte and Corsair PSUs of 600W at low prices!
If my PSU turns ON with the clip trick, but turns OFF just after plugin something to any rail,
what could it be?
It can be ON as long as I don't connect anything to any rail.
Can you fix my iPad Air 2
Hello I'm a big fan Hugh
Me too
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.
Desolder it and see if you can search the model numebr

Hey I have a question, I hope you see this. My iPhone 6 had water damage, I dried it off good, I put it in rice, the only thing that went wrong is that I didn’t turn off the phone. 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?
NEVER PUT A WET SMARTPHONE INTO RICE AS THE STARCH WILL GET INSIDE THE DEVICE AND LITERALLY RUIN THE DEVICE AND THE COMPONENTS TOO
REPLACING A WATER DAMAGED DEVICE WITH A NEW ONE IS THE EASIEST THING TO DO
U can short the caps with a big resistor.
No wonder it blew up. look at that Chinese firecracker. Please just buy a new one, I beg you.
My experience with recapping: Since no one else seemed to mention it, don't replace caps with the Fuhiyyu brand. They are some of the worst. I once had to repair an ATX psu where every single cap was Fuhiyyu brand, and they were all bad, from 2200 uf all the way down to 0.1 uf.
Hi Hugh i have a shatters iPhone four one day can you fix it

Did you get a new camera?
Few days ago mu psu also blew up but it was big caps on the input side two 200v caps blew up from High voltage
What’s the note 7 for? 💥
I'd rather buy few years old PSU used and convert it into bench power supply. I got Antec Neo HE500 for 10€ and it's from 2005.. And about that capacitor discharge time, 20-30 minutes from unplugging is okay for ATX PSU before it's safe to work inside of it with insulated tools. That's what i have been told
Are you working on a Samsung Galaxy Note 7
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.
Good job! Make some videos!
One of the PSU chips exploded while trying to troubleshoot why the scrapped office computer I got wouldn't turn on.
Can you please repair another iPhone 3GS?
