You sound like someone making fun of an accent 😅 Comment from : Ricky Anthony

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 on brWhen 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 intermittent brCan a capacitor cause this? Comment from : RedX

Borat is that YOU ??? thanks 4 the video! Comment from : Πανος Πανου

do you have any video on how to test that "socket" with lightbulb for lights instead of mainsbreaker? could be nice video Comment from : Jan Pedersen

Well explained Comment from : gonedoneg gonedoneg

Great video, thank you! Comment from : Paul Dery

Hey man you are AWESOME! & I love your videos! The only thing that bugged me was how LITTLE flux you used lol, I'm the kind of person that drowns it in flux lol, but for real though you got some good content keep it up! Comment from : RealfamVigilante

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?? Comment from : wibu=cứt chó

Thank you so much Im a noob, so i guess buying a new onecwil be better on a short solution Got a lot of power supplies Will try in future Comment from : Jakes

Thanks 🙏 Comment from : berglundsimon

how did you create the short tester box i need one also plz Comment from : Charles Bwalya

New here Notice pls Comment from : ka Life TV

So the Acer 220w PSU I have does not boot the computer (another PSU starts it so it is the PSU that is the issue) You can hear a lower than normal crackle when you plug it in brbrI cant see any puffed capacitor or anything loose or anything burned I do not have a multimeter right now brbrAnd it has no visible fuse on any side of the circuitboardbrbrThe computer was filled with dust when I found it (CPU packed with thick dust) so I think there might be some overheating isssue that caused itbrbrDo you have any suggestions Comment from : Micke Grus (Michael Gravel)

Putting this video in my favorites! Comment from : Micke Grus (Michael Gravel)

vgood presentation Thanks so much 👍👍👍 Comment from : Oumar Abagaro

Fixing a power supply is a labour of love as you can buy another junked computer and take the power supply out of that I still like to try to fix things Comment from : Tech Terminal

My Cooler master 450 watt supply is not working on load After testing it I found two faulty Transistors and one zener diode After replacing components and testing in series the Power supply fan is running by shorting green and black wire of 24 pin socket but on installing in the computer it hardly works for 2 seconds and stops immediately I have checked all componentsAll are good but still the power supply is not working on load My supply IC is ST9S429-PG14 What could be the possible reason? Please help Comment from : Euphoria Chemistry Classes

DISCHARGE THE CAPACITORS! Otherwise good video missing crucial safety instructions Comment from : szaszm

After watching this, I therefore conclude the $40 replacement for my busted PSU will be worth it 🥹 Comment from : Rouge Avillano

Good explanation but I don't quite get the point of the home made PSU tester when you can buy one that actually gives a voltage reading on each rail for about €6 including postage Comment from : Learn Electronics Repair

Thank you very much for the video I learned a lot of things including the measurements of the different components But I have two powers supplies in trouble I wanted to check if their ICs are in short circuits according to the datasheet using their references in google, but I did not find anything in the datasheet for these 2 ICs The references of the ICs are: KA305850543H and KA251600515 H br Question: How to find these 2 ICs in the datasheet using google Thank you so much Comment from : عمارة حامدي

thank you very much that interested me a lot especially when the measurements are taken with the power off Comment from : عمارة حامدي
