Lab bench power supply from ATX PSU

Lab bench power supply from ATX PSU

As I mentioned in my previous post I’m planing on doing some hardware building soon so I’m going to need a bench top power supply. Instead of dropping a few hundred dollars on a legit one I decided to just build a simple one myself out of an old ATX computer power supply I had laying around.

I started with the guide by Matthew Becker found on his website [link]

He built the terminals into the power supply itself and his finished product looks like this

My PSU was very similar to his except it’s fan was mounted on the inside.

It quickly became apparent that my puny cordless drill was not going allow me to build the terminals into the existing casing.

Instead I opted to build my own enclosure from a radio shack project box I had laying around.

Here it is put together. Notice the special 9 pin molex connector I added to the PSU.

Here it is in place with some labels.

As to reduce clutter since my electronics bench is pretty small I ended up hanging the PSU underneath.

Thats pretty much it, a simple bench top power supply from ATX PSU.
