@@HaseebElectronics have a great day sir. i am your follower here in the philippines. i have a question regarding this computer power supply because we can buy a cheap price of this a secondhand. i plan to make this ATX to supply my booster amplier with an input voltage of 45v dc, can i increase the voltage for up to 45v dc? how about the current because my atx supply indicates 25ampere 12v+ it means if i increase the voltage to 45v the ampere is the same 25ampere or it will decrease to 5ampere something. but how can i get 45v dc of this power supply. i hope you can read my message. thanks.

Thank you for your video sir, I have only little knowledge in electronics.... But I'm very interested to try your tutorial... I'm planning to use my cpu power supply to supply my car amplifier which is 12 volts 3600 watts... I will use your video as my guide... Thank you very much sir, I hope many people will learn and to have a very good knowledge because of your blog... Many thanks sir... Keepsafe... GODBLESS

[@HaseebElectronics]

You are most welcome if you are using computer power supply, most of time, maximum output can be taken from computer power supply that is 400-700 watts. while 12 volt section can provide maximum 200 watts in an excellent power supply. that will not enough to run your amplifier. moreover, you need to remove protections and then it is doable wishing you best of luck and success

Thank you sir for being such a good source of inspiration to us. We so much value your depth of knowledge and experience in this field. I did modified my ATX unit and the output varied properly I'm yet to add a suitable load though. But I also want to point to a problem I encountered and what I did as a solution. Problem:>>>> After using this trick I noticed that power resistors at the output became very hot. Solution:>>>> I removed them know they were working as a dummy load and for current measurement purposely. I'll replace it later though with a suitable one. But i'm posting this because I know some people will encounter such. And I also want to ask if you as well encountered this same problem? ....... Hope to get your response or anyone's response.

[@FUNIXID]

What should we do if we want to have a 12V power supply voltage from zero to 30 volts?

[@HaseebElectronics]

by controlling the duty cycle of any smps controller it is impossible you can use a linear voltage regulator and current regulator in the output

[@tksalalah]

What about the transformer which was designed for the 12 volt dc output plz explaine

[@SWARAJSINGH2008]

Good. How can we modify the protection circuits (the resistance network) also for higher voltage.

[@adrianbestboy98]

I've replaced the 16V 1000uF capacitor from output with 25V 1000uF capacitor but it's going up to 18V, should i buy a 35V or it has something to do with the fact that i've soldered a 2K resistor for ground(i haven't had a 1K when i wanted to test it)

Hi, thank you very much for the helpful information. I need a regulation between 2V and 11-12V. I suppose that 12 volts output cannot go so low, but is it possible to use the 5 volts output for such a range? If not, what is the max range that it can provide? Thanks!

Hi, i have an ATX PSU with only 1 IC 'SG6105D' BAZ33780351E . Can i do a a similar modification to use it as a battery charger.

[@AH-oe2zl]

Can someone explain why psu is turning off when load is connected? Is that because load consumes more power than psu is rated for? What about normal work? How psu knows when to not cut off power?

[@HaseebElectronics]

almost all power supplies have output supervisor IC, that IC monitors the output voltage for undervoltage and overvoltage and imbalancing between the output lines if any voltage drops, the second line will incraese, thus the supervisor ic will turn off the PWM controller IC in case any output capacitor gets open or short circuited or leaked, the volatge values on supervisor IC's input lines (sense lines for 3.3 volt, 5 volt, 12 volt) will change and it will terminate the PSON interlock to disable PWM drive please consult the datasheet for supervisor IC installed in your PSU's output stage

[@Brison1949]

Thank you Haseeb, your videos are so informative, just a question is there a way to increase the amperage for laptop fault finding ?

[@HaseebElectronics]

best regards we cannot increase amperes, because the transformer is limited at a rated current, if we will try to draw more current by hacking the protection, it will cause to overheat the transformer, MOSFETs and it will lead to destroy it rapidly

[@daryo_pl]

​@@HaseebElectronics Hi Haseeb, but how about rewinding second side of transformer to replace ​unused 5V and 3.3V windings with extra copper for increase output current?

[@nasirmehmood3585]

Can we use 20k potentiometer instead of 10k potentiometer and then with 10k resitor

[@HaseebElectronics]

no it is much better to use 10K resistor and 10K potentiometer if you will use 20K, at full counter clockwise it will damage the PWM controller IC
