Convert ATX PSU Into Variable Power Supply, Increase ATX Output Voltage. Make Variable Power Supply by Increasing Computer ATX Power Supply Output Voltage. in this video i demonstrated how to make adjustable / variable power supply from computer atx power supply / PSU to make benchtop / workbench power supply OR you can use as 12V car battery charger OR for dc motor based room cooler / desert room cooler or many other projects and applications. Computer ATX Power Supply can be hacked to convert it in very simple steps.
#convert #atx #psu
first disable the overvoltage, undervoltage, overcurrent, short circuit protection by disabling atx supervisor IC or LM339 or any comparator or operation amplifier IC working as ATX housekeeping function.
ATX Bench Power Supply - Convert a Computer Power Supply
Converting Computer ATX Power Supply to Lab Bench Power Supply
How To Disable Voltage & Current Protection from ATX PSU.
i demonstrated TL494 / KA7500 based atx psu, it is using LM339 comparator ic. this works as ATX supervisor ic for housekeeping and monitoring all the atx function and it turns off TL494 /KA7500 in any abnormal case (over voltage, under voltage, short circuit, over current ) it will pull up pin 4 of the TL494/KA7500 that is dead-time control pin when this pin is pulled up above 2 volt, it shutdown the ATX and disables the SMPS controller option
it prevent the atx operation by auto shutdown from under voltage, overvoltage and overcurrent conditions. so you can modify/ Disable short circuit and overload Computer ATX Power Supply into car battery charger or lab power supply for your electronics workbench or you can make it variable dc power supply.

@@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.

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

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.

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
