This is a conceptual circuit diagram of the power train of a typical atx computer power supply unit this schematic does not show the control circuitry thats why you see all mosfet gates and transistor bases are open. The diagram below shows a partial schematic of a 450 watt atx power supply its construction is typical for a modern computer psu with mosfet switches and active power factor correction pfc note that most schematics circulating on the internet depict old style psu with bipolar transistors and without pfc. 200w atx pc power supply introduction here i bring you wiring diagram of pcs power supply of dtk company this power supply has atx design and 200w performance i was drawed diagram when i repaired this power supply schematics diagram circuit description this power supply circuit uses chip tl494. A good dc switching power supply circuit form old computer that not used it has used powerful durable and works great present a computer becomes the electric appliance power needed for every home because there are very useful. Computer power supplies cost around us30 but lab power supplies can run you 100 or more by converting the cheap free atx power supplies that can be found in any discarded computer you can get a phenomenal lab power supply with huge current outputs short circuit protection and reasonably tight voltage regulation on the 5v line
