You are most welcome

[@magainfotech1059]

Very useful teaching sir....thanks for lot of information.....

[@LCIIT]

Thank you

[@diegomr6969]

my friend, i think the controller pwm not send pulses on DRIVER... just only send stable voltage, and the driver send pulses to mosfets. And add this : you have 3 mode of supply in IT (super io) : 1_ with vbat 2_ with ps connected on motherboard without start (3vsb ) and 3_ when you start is the avcc3 (power analog) this is for IO "ITE" general. some brands change this terms.etc but this video is genial!

[@LCIIT]

There are 4 stage of any buck converter regulator. First controller, who send pwm to drivers, then drivers generate high gate, low gate frequency to regulator that is upper mosfet and lower mosfet. after that last stage is filteration where coil and capacitor used.

[@santoshiinfotech3841]

hello, I have an asus kv8x, with atleton 64, old stuff, I use it to play with mame, now it doesn't turn on anymore, I checked all the outputs of the power supply, and everything is ok, (with green and black wire shorted yes active) how do i know if it is the motherboard, which does not send the consent to the psu? or the cpu is faulty? without cpu, the psu, you should activate the same by pressing the button, under normal conditions?

hello sir maine no display ke south bridge faulty wala video dekha to waha par yeh bataya ja raha hai ki no display ke case par hame plt reset check karna hai. agar reset mil raha hai to south bridge ok hai. problem kisi aur section me hai. aur yeh bhi bataya gaya hai ki south bridge tab plt reset generate karta hai jab ise north bridge, clock,cpu core ,etc se power good milta hai. toh mera confuaion yeh hai ki agar kisi aur aection me problem hai to kiya woh power good signal generate karega. agar power good signal generate nahi karega to south bridge plt reset generate nahi karega. to hame kaise pata saleg ki south bridge faulty hai ya phir koi aur section faulty hai

[@LCIIT]

according to power sequence , south bridge ke baad bios, northbridge, ram etc. ka kaam start hota hai. agar plt reset aa raha hai to iska matlab ki board ki sabhi supply ok hai, jaise ram circuit ki supply ok hai lekin koi jaruri nhi ki ram ok hi ho, isi tarah bios ok ho ya na ho plt reset ok hoga. plt reset ok hoga lekin is baat ki surety nhi ki cpu reset, dram reset etc. ok hi ho.

check ps on line for shorting. there may be any leaky capacitor ............ if track is fine then replace io chip
