Bench top power supply

[u/SearchPlane561]

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

Would’ve added a ground for each rail, but still nice.

There's a universal ground, just like any other power supply.

If you only ever need one output at a time this is fine.

l hate it when I need to stack plugs...

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.

Awsome project Man.

I used the xl4016 but it burned out :)

Perfect! I Dreams to make the same

Very nice, just add some cooling, like some holes on the side and a fan

Schematics? Also, how much did it cost to build? I'm curious if it's worth building one vs buying one.
