Hello friends! In this episode I will show you how I converted an old ATX PSU into a bench power supply with fixed and variable outputs. Some of you asked me for this video, but I also wanted to make it for a long time. Now I have a more colorful power supply that will replace my 2 old ones. A big THANK YOU to all my patrons, especially to: Max Rice, techge and Anthony Ortenzi.
