Similar circuit is used in the most power supplies with output power about 200W. puter Power Supply Schematic and Operation Theory This tutorial is designed to help you better understand the operation of an SMPS. 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). How to Power Up an ATX Power Supply Without a PC!: 3 Steps How to Power Up an ATX Power Supply Without a PC!: In this instructable i will show you how to power up an ATX Power Supply without a PC. Maybe in some cases you want to test an old CD Rom Drive or something else. All that you have is a PSU from an old PC an a wire. Here I show you how do to it. ATX power supply – Circuit Wiring Diagrams ATX power supply provides a 5 V standby voltage, when power is used. This standby power controls a small circuit on the mainboard, also the power switch that connected to the housing. If you push this switch, it triggers the power on management of the power supply to ground, which will turn the led and power supply turn on . How to Convert a puter ATX Power Supply to a ... wikiHow puter power supplies cost around US$30, 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.
