DIYer upcycles an old PC PSU into a flexible bench power supply — 20-year-old relic rescued from dusty neglect

A DIYer transforms an old PC power supply unit (PSU) from the Pentium 4 era into a flexible bench power supply in a 5-minute video tutorial. The tutorial highlights the process of repurposing the PSU, including cleaning the dusty fan, stripping down the unit, and creating a new chassis with a 3D-printed frame and panel. Key components added to the bench power supply include a voltage regulator, connectors for adjustable voltage output, various sockets, an on/off switch, and an LED indicator. While the project is a creative way to upcycle e-waste, it may pose challenges for beginners due to wiring complexities and the lack of detailed written instructions.
