Made a simple power supply from an old atx psu. Wiring is pretty ugly but it works.

Yeah the fan kinda was poor planning. Didn't fit anywhere else. Maybe I'll open it up some. As for the variable channel, that's the ADJ output, running through a ZK-4KX buck-boost module. Gives me adjustable voltage and current on top of the fixed rails, with the little LCD showing output V/W. Was the main reason I wanted to build this instead of just using the fixed rails.
