12+ Atx Psu Schematic. Today i tried to repair a big 850w atx computer power supply. It had quite a lot of faulty components, so instead of fixing it, i decided to reverse.
Its construction is typical for a modern computer psu with mosfet switches and active power factor correction (pfc). Them as you can see at the attached schematic (instead of ac/dc converter i used my old psu). Schematics of halfbridge atx (at) supplies with tl494, ka7500 ics tl494 and ka7500 are equivalent.
