Lesson 1: Power Supplies

This lesson presents basic information about power supplies for computer systems. We take a look at the different sizes of power supplies, how to connect them to a computer (motherboard and related devices), and how to deal with the safety considerations that arise. As a certified computer technician, you will often be called upon to troubleshoot, identify, and replace power supplies.

After this lesson, you will be able to:
  • Define the current and voltage requirements for a computer power supply.
  • Identify a replacement power supply.
  • Specify the correct surge suppressors for a computer system.
  • Specify a backup power supply for a computer system.
