Appendix F Power Supply When determining the type of power supply unit needed to run your computer and its components, keep in mind the following factors: Maximum output: This is the number of watts the power supply is capable of delivering. The higher the wattage, the more available power there is. By determining the amount of wattage you need to run a computer, you may avoid spending more money than necessary on the power supply. Efficiency rating: This determines how much energy your power supply uses to deliver the necessary wattage to run your computer. Most power supplies have efficiency rating of 70% or higher at full load. Cooling: The more wattage available, the more heat is produced. The power supply must have at least one 80 mm fan to cool the system. Power supplies with over 400 watts must have two 80 mm fans or one 120 mm fan to effectively cool the machine. Power connectors: Make sure the power supply comes with enough power connectors to run your computer. Activity One, Part A: Determining Wattage Using the Comparing Computers chart, determine how much power you would need to run your dream computer. In the chart below, list the make and model of your computer’s components and research online to determine how much wattage is required to run each.
