Computer hardware technicians must understand the basics of computer power systems, including amps, wattage, voltage, general guidelines for power sizing, and power supply options. Explore key power systems lessons like differentiating between power supply inputs and outputs, identifying the values needed for components, such as overall wattage rating, and determining the amount of power needed based on the number of devices in use. Examine the characteristics of redundant power supplies and modular power supplies. Finally, put your new skills to use solving a problem to determine when to use more or less voltage, how to describe wattage ratings, and how to determine the output of a rail on power supply. This course will prepare learners for the CompTIA A+ Core 1 (220-1101) certification.
