How Many Watts does a Computer System Use?
A complete desktop uses an average of 200 Watt hours (Wh). This is the sum of the average consumption per hour of the computer itself (171 W), the internet modem (10 W), the printer (5 W) and the loudspeakers (20 W). Assuming that a computer is on for eight hours a day, the annual consumption comes to 600 kWh.
How do I Check my PC Power Consumption?
To measure your PCs usage, turn everything off, plug your PC into the KillAWatt, then plug the KillAWatt into the wall. I actually recommend plugging your entire surge protector into the KillAWatt—that way, you measure not just the PCs energy usage, but the monitor, speakers, and other peripherals as well.
How To Check How Much Power a Windows PC or Mac is Using
Navigate to “Settings” and click on “My Power Tab.” You'll see a rough estimate of how much power your PC uses.
How do I Know that the PSU is the Right Size?
Every PC case has a space for the power supply unit although the space may vary in size and shape. For example, small form factor cases will not be able to accommodate a PSU meant for a mid or full tower case. It is always best to look at the dimensions of your PC case and make sure that you are buying a power supply unit that can fit in the designated space.
