Overview
ATX breakout is an open-source printed circuit board by Duckle29, from the Duckle29/ATX-Power-breakout repository on GitHub, published under the MIT licence. It is a 2-layer board of 67 × 59.5 mm with 28 parts on 43 nets, routed with 225 tracks and 54 vias.
Its parts include 13 connectors, 6 resistors and 1 transistor. It belongs with the interfaces and adapters boards of this library.
README
readme.mdPi ATX power breakout
This is just a simple board that breaks out the different rails of an ATX 24pin connector. It's mainly intented to be used for powering a Raspberry Pi and a 3D printer.
The board includes an EPS 4pin connector as well, allowing for up to 32A on the 12v rail. If you slightly overrun the rated 8A per cable, the 3 12v connectors will handle up to 36A (12A each). This is a 12.5% overload at 9A per cable. Most good cables/connectors should handle that.
The other rails can output 12A max, if the PSU can supply that on that rail.
The board also has a header for selecting how to control the PS_ON signal. It can either be controlled via a transistor controled by the RPi. Aditionally, the "Power Good" signal is also connected to the pi (through a voltage dividier). Lastly, the I2C interface of the Pi is exposed on a 5 pin header, along with 5V 3V3 and Ground.
The 5V supply for the I2C connector and the Pi is selected through the the jumper JP1, while the 5V supply for the USB connector is selected via JP2. You can select between the 5V rail, or the 5V standby rail.

Questions
How big is the ATX breakout PCB?
It measures 67 × 59.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ATX breakout use?
28 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.
Where can I download the ATX breakout KiCad files?
From the Duckle29/ATX-Power-breakout repository on GitHub, at the commit this page was made from: the board is ATX-breakout.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the ATX breakout design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
