Examine the vital basics of computer power systems, including amps, wattage, voltage, general guidelines for power sizing, and power supply options. The key power system lessons in this course include discussing input, specifically differentiating between 115V versus 220V and output 5.5V versus 12V; the 24-pin motherboard adapter, sometimes referred to as the ATX 24-pin, which supplies power to all components of your motherboard; identifying what kind of values you need for components, such as overall wattage rating and the volts that are being supplied to ensure that you do not exceed the maximum wattage output; and determining the amount of power needed, based on the number of devices in use. This course concludes with an exercise on working with power supplies, which will help learners determine when to use more or less volts; learning how to differentiate between AC and DC; how to describe wattage ratings; and learning how to determine the maximum output of a rail on power supply. This course can be used to help prepare for the 220-1001: CompTIA A+ certification exam.
