I had been building enclosures for pixel controllers for a little while on much smaller scales but Event Horizon required a lot of power and all in one place, so I decided it was a worth while project to embark on making the largest cooled, 5V system yet, capable of delivering a maximum of 480 Amps across 48 outputs over Anderson Powerpole high current connectors.

To help combat voltage drop, which 5V leds are notorious for I added 48 additional outputs just below the main outputs, for an optional power injection anywhere it was needed.

I also opted to use my TAZ4's large print bed surface to make the individual panels that house the connectors and that way I was able to incorporate port labels directly as embossed lettering.

The metal framing was built with Open Builds, I love that they offer detailed cad files for everything they sell, so it makes it very convenient for me to fully mock up a digital version of something, all nuts, bolts, and connectors accounted for.

The following set of photos takes you through the entire process I went through.
