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:-
understanding atx power supply basics circuit diagram schematic with complete tutorial

thanks for videos, how to select resistor 1k, 680, 3.3 for 5v. 4v, 12v these voltage,

[@giangem37]

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?

[@daudtahir7130]

Please make a video on SG6105ADZ ic

[@bibhashalder1927]

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.

[@rachid746]

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?

[@IanBLacy]

Can’t start motors because it trips the overcurrent on startup

[@cleo585]

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. Hugo

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

[@cleo585]

@@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.
