ATX PSU Adapter for DIY projects
ATX PSU Adapter is an open-source printed circuit board by Yanndroid, from the Yanndroid/ATX-PSU-Adapter repository on GitHub. It is a 2-layer board of 66 × 48 mm with 33 parts on 11 nets, routed with 63 tracks and 1 via.
Its parts include 27 connectors, 1 resistor and 1 IC. It belongs with the power and interfaces and adapters boards of this library.
This simple breakout board for a 24-pin ATX power supply provides 12V, 5V, 3.3V, and standby 5V. Additionally, it also has a small circuit to control the PSU.
Personally, I'm using this PCB to power my Raspberry Pi via the standby 5V line and can automatically turn the PSU on or off for other devices that also draw power from the PSU.

It measures 66 × 48 mm and has 2 copper layers, 1.6 mm thick.
33 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the Yanndroid/ATX-PSU-Adapter repository on GitHub, at the commit this page was made from: the board is ATX-PSU-Adapter.kicad_pcb and its schematic ATX-PSU-Adapter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask Yanndroid before reusing the design.
