Professor Messer’s Free CompTIA A+ Certification Training Course – Personal Computer Power

Chapter 8: Personal Computer Power

Power is an important part of every computer system in the world, and every CompTIA A+ certified professional should be able to understand, specify, and troubleshoot power problems in any environment.

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.

Troubleshooting power problems with personal computers goes well beyond the power cord. In this module, we’ll show you how to use a circuit tester and multimeter to troubleshoot power on the motherboard , the PC components, and the power outlets themselves. You’ll also learn about power protection systems and the process for installing a PC power supply.
