Atx Power Supply Wiring Diagram. If you have an ATX power supply with a 24 pin main cable its okay to plug it into a motherboard with a 20 pin connector. By the way you cant test an ATX power supply without load otherwise it may turned On for a while and then shut down.
An annotated schematic of 250W ATX power supply with active power factor correction PFC. Computer Schematic Ford Escape Fuel Pump Wiring Bege Diagram. Rare and Ancient Equipment DELTA Power Supply DPS-470 delta_dps-470_ab_a.
Its construction is typical for a modern computer PSU with MOSFET switches and active power factor correction PFC.
This power supply circuit uses chip TL494. Device use push-pull transistor circuit with regulation of output. ATX specification includes not only Power Supply Unit but also interface to case and motherboard. By the way you cant test an ATX power supply without load otherwise it may turned On for a while and then shut down.
