One thing that every man’s cave needs is a power supply. I already have a 12volt regulated power supply but my interest in micro-controllers makes it ncessary to have other voltages available.
Enter the ATX power supply. The ATX power supply is found in most recent computers and many a time I’ve thrown them out in my work. I decided that the power supply from one of my old machines looked too new to junk and so I began the Bench Power Supply.
There are many instructables and how-to’s on the net which outline the process of modifying your power supply for use with other projects.
The simplest of these is to use the voltages output by the PSU without any modifications. This was my choice for this power supply project.
