Due to the PFC, my current limiter bulb keeps blinking Is it safe to bypass the PFC for testing? I intend to desolder the PFC inductor

I have a cooler master and inside are 2 huge capacitors, one of which is leaking electrolytic fluid, swollen at the top PC does not turn onbrWhen i bridge Green and Black and switch on PSU the fan does spin ok, but when i try again the fan does not spin, it is intermittentbrCan a capacitor cause this?

youre wxplaining this to someone who after 5 years of learning electronics , you would give him one last lesson
Comment from : caine 072

you're explaining how to repair these power supplies to someone who already knows hot to fix it , and for someone who already knows how to make a scheme on paper
Comment from : caine 072

Yeah

Hello Sir, very informative video, I am currently modifying a power supply and noticed that one of the 3,3 V wires is connected to a brown wire, which senses the v outputbrIf I want to use the ATX for a 3,3/5/12 volt supply should I als connect this brown wire or can I cut it loose?brbrregbrDirk Bosman

I replaced the 240v fuse for the broken psu with a 250v fuse available be burnt , but plugged it in and it exploded! So just use the equivalent 250v fuse??

Your videos are a great learning aid I'm still trying to digest it all I have a micro-ATX with a -12v line that reads -115v That doesn't seem too far off, but it won't boot my old Amiga 4000 anymore I compared levels to those from an original Commodore PSU that will boot the Amiga 4000, and the only significant difference is that -12v line The original PSU is reading almost -12v on the nose The problem with the original PSU is it's only 145W and when I load up the Amiga with all the expansion cards and drives that's underpowered The micro-ATX is 350W, plus the smaller form factor makes cable management in the cramped Amiga case easier Can I bring that -115v closer to -12v? is this an aging capacitor issue? Or should I be looking for a different problem/solution? Thanks

When PSU turning off during load have i check all capacitors? Whad do you think, how to find issue?
Comment from : Miłosz

Hi there, I'm not a technical expert or a monster but I love the electronic thing, and I will try to repair my power supply following your guidance,hopefully, I hope to do it, of course, of course I don't have the perfect tools but it does matter the most important is to be careful and patient Thank you for everything,👍ciao!👋

Just a little constructive criticism Your audio is very low, compared to the ads Just sayin
Comment from : notsogreat123

very annoying listening “yeh” all the time in every sentence, I couldn’t watch the hole video
Comment from : M M

Well I soldered a trace on the pcb that had burned and broke connection and tried the green and black wire and the fan came on this time I just need to test the pinouts and make shure there right before I connect to the motherboard
Comment from : auto_chris420

Stop talking with the word "YEA" after every sentence!!!😕😕 It's very difficult to stay listening to you!!!
Comment from : Phil Garcia

Yeah 👍
Comment from : Sikandar Baloch

Soo cool and in depth Thanks Very fascinating
Comment from : Nathan Gibson

Did you talked about resonant stages of some atx psus in some of your videos? seems like this relative new technology give us a lot of tricky to find issues in this psu designs Regards
Comment from : Pablo Soto

I don't suppose you could do the same video but for "AT" PSU if you ever have the time ?? :) I have been trying to follow along but ATX PSU and AT PSU are quite different
Comment from : kane

Thanks for the very informative video I've tried to repair a psu that gives out 3,7 and 12vdc I measured the outputs and all seem fine, but the tech comes back telling me that it is still faulty It seems to be unable to maintain the voltages under load What would be the component or area that I'd need to investigate further? Thanking you in advance and a merry Christmas from Galway, Ireland

HELLO LER! Am an avid Subscriber, you are my first 'Go to' when diagnosing PC issues! I recently built a new Computer in my old Tower with a new Raidmax Vampire 1000W 80 Plus Gold Power Supply, an MSI Z390-A PRO Motherboard with an Intel Pentium Gold Processor G5400 CPU @ 37GHz! Next added 640 GB DDR4 3200 Ram! Also a ZOTAC GAMING GeForce GTX 1 Video Card! Recently upgraded all my HHD's with an Intel 660p Series M2 1 TB SSD Drive C and two WD I TB internal SSD's! My Computer now boots up completely for a cold start in 30 seconds!!!! (Once in a while when I turn it on, it Boots into the Bios Screen)!!!(But when I wont to boot into Bios, no matter what key combination I press it wont go into Bios on Command)! Windows will not display on my Digital Monitor but I can see the Bios Screen on another HDMI Output to my 32 inch TV! Am running XMP Mode and Gaming Mode on the MSI along with allocating 3/4 of my Ram to Process my Adobe Premiere 2022! My Question is: How do I get the computer to Boot into Windows EVERY TIME? And secondly, How do I get my computer to boot into Bios on command?

my PSU's 5v[red] is drooping with a ripple and 11khz according to my multimeter itll droop to 44VDC any fix ideas?
Comment from : Galen Thurber

Great outline of the supply components - & no doubt you’ve saved some lives too - I’ve obviously been lucky that I’m still here - so Thank-you! 👍
Comment from : messageobliquespe100

This channel is all you need to know about Autoplay, once you are on this channel, you will never see autoplay work again! (At least this is my experience, 90 of the time I end up on this channel and it never leaves once there, just plays this channels video's forever Really infuriating!!!) Went from enjoying the channel to cursing it every time it comes on
Comment from : Whoisnt Whoisit

why would anyone consider repairing all those garbage PSUs maybe environmental reasons or youtube content
Comment from : cookytrix

Comment from : Chau

Hi, I think my psu is not working properly My computer keeps getting restart and yesterday same happened in biosI tested my GPU and everything and I think it's the power supply that's causing and problem If I shake the ATX cable a few times it shuts down Please help

🙏please 🙏 stop too much time west
Comment from : PSNV Prasad

Explanation good but middle middle your worest jocks make too Much time west
Comment from : PSNV Prasad

Thanks for the video buddy! The supply you were using as an example is almost exactly the same as the one I'm going to attempt to repair, close enough that I could identify all the components you were talking about 😊 I'll be following your tutorial I had already checked the 5v stb before finding your video, now on to the common faults 😁

I wonder how many yeahs in this video
Comment from : Rainbrony Huang

I would stick up for my buddy diode gone wild and his YouTube channel and videos on repairing ATX power supplies Maybe not as comprehensive but just as valuable And you were both excellent teachers and very skilled at explaining electronics engineering and repair type stuff Much love from the USA!

How interesting it may be, I can't listen to a guy who's every second word is: "yeah"

ATX PSU whining making high pitched noises but fully functional and no bulging caps possible causes?
Comment from : Super Computing

Hi Richard, would a 40W "old technology" light bulb be enough for a current limiter?

Hi Brian It would be better rather than saying the green wire if you said which pin on the ATX power supply as the colours can be different due to the manufacturer so if you could state that it would help the new be also how best to test the individual components

Thank u master, thanks sharing of the knowledge for atleast understanding how psu works so we have an idea to repair ours
Comment from : KIMMY0312

Thanks for this! I am converting an old ATX into a benchtop supply for general mad-scientist type stuff and thought it was shot I knew there was a 5v Standby but didn't realize it actually needed to be grounded in order for the rest of the supply to fire up Thanks for all the good info, keep up the good work!
Comment from : Brian Terry

Those arrows on diode bridge are quite missleading on your drawing Those diodes allow current only one way So your explanation at 45:54 is missleading for me Because current is not flowing through that diode you are showing Also that half time is live and half time neutral does not make sense to me neither I think you probably have drawed that bridge in different way you are used to That heatsink is always placed on negative based on your bridge drawing So it is safe to touch Anyway i like your videoseven this one ;-)

I have repair my 550w PSU, the broken items are N-FET 13N50C and diode IN5408 The PSU is working now, but i have some problem, when im playing roblox with full graphics quality, my pc get turn off it never happen before my psu broke can you help me?
Comment from : Ria Yoe

No 7 or 15 if I'm not too latebrYour too quick, I'm watching it now Thanks fot the great info
Comment from : Mark Lee

Well presented, well explained, what more could you want - thankyou, if it were up to me I would choose to fix PSU's that had more on the 12v rail than the lower ones, more modern boards have power delivery issues with the old style atx psu's and can make the psu appear faulty when they arent- but they still have their uses even if not connected to a pc :) keep up the good work
