- in this video i demonstrated How to bypass Over Voltage Protection in ATX power supply using SDC291 Voltage mode PWM SMPS controller Power Supply For Higher Output Voltage
i explained practical How to repair computer ATX switch mode power supply SMPS very easy. this PSU is using SDC2921 IC which is PWM and intelligent power supply monitor. i simulated the outputs of the power supply using a voltage divider network supplied with +5V SB local power supply. after watching this video you can capable to:-

Assalamualaikum dear Brother.Excellent and Great tutorial as always.Thanks for sharing your valuable work.
great video ... thank you for sharing this video ,,, master tech...
You are welcome
I loved this as it is very hard for me to get hold of IC chips so i pass on any IC fault repairs
Nice video my dear Hasseb Electronics.

Hello thank you for inviting me to join your interesting channel full support returned and welcome
Nice
Sure this is fun for me, & more fun if we can modify It to variable voltage 0-28v
Nice vids, Thank You !!
Thank You, waiting for that :)
I m also waiting for that video, if u got that pls Give me link 🌹🙏🏻
I think on last video this channel, there is modified atx variable voltages, already - pls, search it on this awesome channel.
Nice👍

Thank you for good tip video, i has an ATX psu (named andyson e5 400W) with LA8100PN same as SDC2921, when i PS-ON the fan only spin 2, 3 round and off, i check every thing and can't find problem, so i use your trick at this video, so fk good, the PSU work fine 12V, 5V, and 3V3 is okay. So i think problem is three feedback, i check the resistor fb and that true value, no problem on three line feedback. i check -12V and it has -10,9V, the -12volt line doesn't have line to IC, so i think it not care with IC, so what can i do with this problem, can i use my computer with voltage fb made by resistor on your trick?
محتوئ مفيد كلش
Good.🍎
thanks a lot
Can i replace the sdc2921 i.c. to make it a cc cv power supply with higher voltage output?

Nice video 👍
Sir, in my smps circuit sdc2921 ic has two resistors connected, one resistor connected to +12 volt and the other connected to -12 volt, should I disconnect both?
Please reply
Hi
Which pin is control curent in sdc 2921
Thank you
Nice....
How about remove protect ic 2005Z?
Pl discuss about complete troubleshooting of this power supply using SDC 606 and SDC 2921
I like the process and the idea behind it. but I still don't get it: why do you need to bypass the sens circuitry? isn't it better to leave it with short-circuit protection on? what's your objective?
Can’t start motors because it trips the overcurrent on startup
Does this bypass method apply to this IC? WT7527?
No 7527 have deifferent pinout. i will try to share complete procedure soon

thanks for videos, how to select resistor 1k, 680, 3.3 for 5v. 4v, 12v these voltage,
Can I mod my antec 350 watt branded smps. And still use it in my computer system.?. I mean is it safe ????
السلام عليكم ورحمة الله اخوي
Dear Sir, fist of all, thank you very much for sharing your video.
I have 2 doubts: at min 12:10 you said that must cut the line to disconnect some part of the circuit. Same at and min 12:34 also said to disconnect other section.
As my board is completely different than yours, I am stacked and I don't know what must cut. I am afraid to make a mistake and I ask you to explain me where to do that.
Thanks a lot for your quick reply.
Kind regards from Principality of Andorra.

most welcome brother
my humble request to please wait for couple of days (less than a week) . i will share a complete and very detailed tutorial, so that it will fit in every kind of ATX
@@HaseebElectronics Thank you for your very quick reply.
I will wait for your new video, but maybe in the meantime, you can bring me some tip about my question. I have the power supply completely disassembled on my desk :-))
Thanks for your generous sharing of your knowledge.
Sir, I also try this method on atx smps based HS8110 pwm ic. But the result is output 12v increase 14.8v, 5v increase 6.32 & 3.3v increase 4.06. So sir how can solve the problem? Please help me.
Hello, can u help me with my atx powersupply, i want to bypass over voltage/current protection.. the i.c. of my atx is tsm111cn
Thank you,, can i have your email so i can contact you directly.
Sir plz make an videos led lcd TVs smps
Waalaikum salam bro
Assalm alekum sir is smps ko battery charger Mai kese Karen ge please help me
Sir, After this modification it's provide 24volt! how can I adjust 15volt?
Good night Hey brother, what kind of components have been replaced by a potentiometer please practice one by one I am still confused, thankyou
welcome dear. i will explain in complete detail and will demonstrate every step in more detail
@@HaseebElectronics thank you brother, i am waiting for a simple video
Assalaamu 'alaikum🙏 sorry I want to ask my brother, what if the 3.3v - 5v - and 12v lines are not disconnected???
Sir, can I apply this bypass method SG6105DZ- IC?
almost every supervisor ics work in the same ways. so bypass is done in the same method. just we have to ensure the pin configuration
@@HaseebElectronics ok thank you sir.
Hello, how did youdo to find the resistors values for the divider ? i am struggling and i cannot find values to go from 5 to 3.775 to 3.375.
@@HaseebElectronicsSalam M.Haseeb. Thanks, indeed I tried 3.3k + 580 + 1K and it falls within range without connecting the IC pins, the 12v sensing pin is connected directly to 5vsb as per its original value, but when i connect the ic pins (DWA103N, pins 10/11/12), the voltage at pins 5v and 3.3v falls below 1v , and i have no more output... any idea ?
@@HaseebElectronics I did unsolder them from the PCB without cutting any trace because the traces are very thin. It was easier for me this way. Voltages are good but when i connect the PINS, it goes fault.
@@HaseebElectronics the 12v is at the far end of the divider because its original value was 5.1v, which is very close to 5vsb. How can i send you a picture ?
@@HaseebElectronicswhen i do connect the PINS to the divider i have no output at the yellow 12v ...
Please make a video on SG6105ADZ ic

Asslam o alikum sir
Mere paas bhi same supply h lekin woh Ac200v sy kam volts pr on nhi hoti
Yeh undervoltage protection ka koi hal h
