Power supply ATX

Atx power supply

Similar projects worth following
I needed a power supply so I decided to make one. I plan on 3-d printing a case if I have time.

I wanted to make a indicator for when the supply is plugged into the wall. The schematic is an image in the project. It is basically a bridge rectifier with a smoothing cap and dropping resistor. This is placed in parallel with the power to the board.


-Resistor 1000 ohm

-4 diodes (N4004)

-1 led

-100nf capacitor (2A1004J)

  • 4 × diodes
  • 1 × LED Fiber Optics / Emitters
  • 1 × Resistor 1000 ohm
  • 1 × Capcitor 100nf

  • Temporary board

    I plan on making some boost and buck converters to add to this. I also have some power resistors as a fake load, since I did some reaserch and under low load these old supplies apparently aren't accurate.

ATX has a 5V standby rail that is always on, so no need to touch the high voltage side at all.
