Every computer system has a power supply, so the CompTIA A+ professional needs to have a solid understanding of personal computer power supply characteristics and types. In this video, you’ll learn about the basics of electricity (i.e., amp, volt, watt), the type of connectors you can expect to see on a power supply, and the industry standards that are used to perfectly match your motherboard with your power supply.
