- Make Variable Power Supply by Increasing Computer ATX Power Supply Output Voltage. Convert ATX PSU Into Variable Power Supply, Increase ATX 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.

sir exelint information video ap great ho sir yah ab batray be chargeing kary ماشاء اللہ جی ماشاء اللہ
thanks a lot bhai
yes bhai. abhi is per aur bhi videos bnaaoon ga. battery charging practical kr k dikhaaoon ga
in-shaa-Allah
Masahallah sir bohot arsee se smps voltage baranay wali videos surching kar raha hu lekin aj tak asee video kisi ne nahi banaye thank you.
السلام علیکم ـ بہت شکریہ سر بہت عمدہ وڈیو ـ

very nice video dear friends thanks for sharing I wish you good health and good luck 💖🌺👍
Very nice haseeb Bhai current control par bhi video zaroor banana Allah app ko khush rakhe
Wonderful video dear friend, have a happy day!
Great Haseeb bhai
Very useful for electronics technicians.thanks for sharing 👍
Excellent informative video keep sharing
Bahot badiya sir
This is very useful sir.
Thank you sir. Good night 🙏
Very good and useful information sir thanks for sharing this knowledge to us
Amazing video ap ki hamesha ki tarah🥰🥰🇦🇪
Awesome. Thank you sir.
Great Mashallah . Allah ilm ma barakat day ameen
MaSha Allah nice sir 🌹♥️♥️💯💯💯👍
Zabardast Haseeb bhai, 👍🥰🌹
Haseeb bhai kaya ic power supply kay volt badha kar hum ab ic say battery charge kar sakte hain, or Dc cooler ki soeed badha sakte hain, please Next video mein ye bat explain zaror kijiye ga Thanks I advance
We had requested you for this video, thank you
sir mujhe is wali supply ko variable banana he 1v to 30v and 100mA to 10A vo bhi variable digital meter bhi add karna he to kya kya modify karna padega please ek video banaiye
جزاك الله خيرا في الدنيا والآخرة
ماشاءاللہ
excellent.thanks bro
You're welcome!
Nice modification.
But I want to know where to supply voltage to cooling fan.
Zabardas sirt
Sahab Atx supply ko dual supply me kese badle is pr ek vedio baiye. Isme jese aapne 12v se 30v veriable kiye kya +12 0 -12 volte se 30 0 30volt veriable banai ja sakti he...
Sir we need this video in English pls .. Thx alot for you efforts, much appreciated
Nice video sir
Really nice 🙂😊
Sir smps me primary and secondary ke ground ke bich lagne vala capesetor nikal de to kya koi prob aayega?? Mere smps me Ac voltege leakage ho raha hai DC output me to iska kya problem ho sakta hai
Very nice sir🙏. Sir mera bhi 1quchan hai, mere pass menwell company ki 24 v. 14.5a. Ki smps hai. Magar muje ushi ko 24-0-24 duyal supply banna hai amplifayar ke liye. Help me🙏🙏.
Will it work as a battery charger at 14v?
sir bypass le baad atx abb 30v pe kitne amp maintain rakh skta hai pls i love it your video
Sir is main + - b le sakte hain? +30 + -30 b le sakte hain? Aur maximum kitne le sakte hain +15 + -15 =30 ya 60
sir agar hum 3.3v ko b use kr k kia 3v say start kr saktay hain taa k mobile ki supply is say bana sakain.?
65-0-65 Tak increase karne ke liye kya kya modify karna padega sir
jo pot 10k lagaya he use dayagram dikhaye to bahut achha hoga.
Sir 36.0.36 ke liye kya kya change karna hoga ?
اسکا ڈائگرام جو آپ نے ویڈیو میں دکھایا ہے وہ مل سکتا ہے؟
Sir mere pas Jo supply Hy wo defrant Hy usme ic dosri h Kya usme ho sakti Hy
Sir plz bataen.ka 7500 ic aur sdc 7500 ic kya same work karti hein ya koi fark hy.agar hy to is py video banaen.
sir protection nahi hatani , laken volt veriable hon,protection humain cheay
Sir प्रणाम, किसी video में समझाये sir कि, votage को स्थिर रखकर current कैसे बढ़ता है या बढ़ाया जाता है sir please इस टॉपिक पर video बनाये क्योकि कहा जाता है कि current तभी बढता है जब voltage बढ़ाया जाता है।
سر کیا اس کو بیٹری چارجر کے طور پر استعمال کر سکتے ہیں ؟
Sir voltage 14volt se upar to ho rhe he 30-32volt tak par 14volt se kam nhi ho rhe meri supply me
65-0-65 banane ke liye kya kya modify karna padega
I have a PC PSU 185 watts. When i try to jump start it(connecting green with ground) it turns on briefly and then stops. The psu is apparently all ok to my understandings but need your help.
its protection circuit is interrupting. check secondary side components (capacitors, rectifiers)
Sir I have dell nsp 200pb-73 M psu i am trying to increase his voltage but my mistake my meter prob touch with its octuocapplier on infrad side and its output voltage shot to 35 volts and the psu is starting without shorting its SB points like before , plz help to repair it
ماشاءالله
Sir good sir you are touching hand to smps board is it ok or not when it is active
Sir 5 ampair chahihe kaise nikale
Amplifair bord ke liye..
Mere pass vi hai jey converter

60 volt ki supply se buck converter bananay ka diagram share kar dain plz.
Sir hum is ko kaha direct karsatey hain kionki green awr black direct tu pir trip hojata hain
Please do current control for the same
Is this applicable to most branded ATX supplies?
Yes of course almost every atx can be hacked, im currently working on HP 8000 psu and im succeed to increase stable output from 12.58v to 14.28v very stable, but im still working to limit the current while charging battery, problem is that my psu has max 16a design but it draw 30+ amps when i try to charge battery which is not acceptable these high current ll kill both ATX and battery as well, so im designing lm358 to limit the current to 15 amps max, the best part is i didnt bypass the internal protection its still active and fully functional 😊
sir, ampere kese baraye please video bana dijiye 🙏🙏🙏
Net p video pri ha pr chines Japanese language m smj ni ah ah ri pleas 7520 ic waly board ki video banye 14 volt kesy kry .please simpl easy way please
Sir atx power supply 7520 p video banye please mehrbni bht se logo ko dikaya h khty humse ni hga ye km

Waiting for current controll
How to convert dc 12v to dc 60v used computer power supply
Sir if I have a 12v 750mamps power supply and i want 5v power supply with same 750mamps
Is it possible by using voltage divider network
Yes its vary simple, for example output voltage = 12v, Voltage feedback = 2.5v So the gain would be 2.5/12 = 0.208. if you want the desired voltage is 5v So new feedback voltage = gain*desired voltage 0.208*5= 1.04v. Now simple you apply ohm law or VDR and find R2. R1 will constant
@@mfahadtauseef63 ok Ji
And will using resistors drop ampares?
@@raoamarjeet5473 yes you will suppose minimum value of current about current < 20mA
@@mfahadtauseef63 ok sir
Hum log mobile repair sikhna chahte hain
Sir agr hum zero volt start krna chaty hu ya minmum 3 volts tk ho jy is k lia guide kr dain ap kindly. JazakAllah.
10 aur 20 ampere china charger auto cut off 14 volt par adjust kese Karen is par Kisi ne abhi tak koi video nahi bani aur ye bohut zaruri hai bohut customer is ki shikayat karte hen agar apko maloom hai 14 volt par kese auto cut off Hogi charging to mujhe Bata den please kese kar sakte hen
👉🥀
can you give a diagram. and how to make 0v-24v with the protection still active
I made my psu 12v to 14.4 volt without destroying psu internal protection, which is the best part that protection is still active and i tested, pas trip if i short circuit and also trip while over and under voltage, and trip if current exceed 16A😊
