Bench power supplies are one of the most useful tools on any electronics workbench, but a good one can cost several hundred dollars. This build takes the pragmatic route: repurpose a discarded ATX power supply — something most of us have in a drawer — and convert it into a proper 0-36V variable bench supply with per-output fuse protection.

What makes this video worth watching over the dozens of similar ATX-to-bench conversions on YouTube is the depth of the deliverables. The creator provides STL files for the enclosure and the exact BOM, so you can actually reproduce the build rather than just admire it. The 0-36V range (as opposed to the usual fixed 3.3V/5V/12V rails you get from a raw ATX pinout) means an adjustable buck-boost stage has been added, which is where the interesting engineering lives — understanding how to safely extract regulated variable output from a switching supply designed for fixed rails.

The fuse-per-output detail is also a nice touch that a lot of hobbyist builds skip. ATX supplies can dump serious current into a short, and without protection you'll cook your project (or worse) the first time a probe slips. This is exactly the kind of channel worth supporting early — a brand-new creator (1 subscriber at time of writing) posting a complete, documented build.
