Explaining PC Power Supplies

Desktop PC power supply units (PSUs) explained, including ATX standards and connectors, modular and non-modular cable options, power and efficiency ratings, and the latest ATX 3.0 developments.

The video in which I fit and test a quiet PSU with a zero-RPM fan at low loads is here:

The first of two videos where I built the Mini-ITX PC is here:
   • Haswell i3 Mini-ITX Build (Part One)  

And I have a more recent, silent Mini-ITX build here:
