What is it?
This big brother to the Mini ATX PSU allows you to power your Raspberry Pi and add-on project boards at much higher currents using inexpensive desktop power supplies while being able to enforce controlled shutdowns of the Pi's operating system to aid in preventing the corruption of valuable disk files. Additionally, the Mini ATX PSU-HP monitors the Raspberry Pi so that, in the case that the Pi is shut down by an application or from the command line, the desktop power supply will also turn off.
Although the Mini ATX PSU-HP has been designed to handle 20 amps of current on the +5VDC and +12VDC supplies from connector J3, live testing this current load has been a challenge. The connector J3 itself is rated for 20 amps on each screw terminal. And, the copper power traces leading from the Molex connector J2 to the screw terminal are at least 10mm wide on 2-ounce copper. So, it should handle 20 amps. However, without proper testing, we cannot guarantee that it will handle this kind of current. Be advised then that when you use this product, you do so at your own risk and that we will not be held liable for any resulting property damage, destruction, and/or personal injury.
Why did you make it?
My projects often need multiple voltages in addition to the 3.3 VDC or 5 VDC supplies usually provided by the Raspberry Pi. Existing ATX type desktop power supplies provide the kind of power that I can use. Additionally, I needed my board to be a HAT conforming board so that I can build controller stacks using the other boards I designed as well as third-party boards. I am very particular in using stacked configurations because a stacked configuration is physically and electrically more robust. Finally, I wanted to mitigate the chance of file corruption by just turning off my Raspberry Pi without doing a controlled shutdown. This board allows me to do this.

I have been a software developer for all of my adult life. A couple of years ago, my old passion for electronics and model railroading got reignited with my first purchase of a Raspberry Pi. Since then, I have created a wonderful open source web app for the Pi, called Breezy4Pi at www.breezy4pi.com. This application enables a hobbyist to program the Raspberry Pi with mere mouse clicks to execute small programs.
Along with Breezy4Pi is the line of I/O extenders, break out boards and, my latest, the Mini ATX PSU. These are all designed to work well together in a compact stack-able configuration appropriate for the general hobbyist and model railroader.
