If you want to be extremely precise with your calculations, you can use a power meter to measure the actual consumption patterns of your devices.Īlternatively, you can look at the power supply rating for your computer as a measure of the maximum power the computer will pull. Let’s start off by determining the power needs of our home server, as it is the most simple of our setups. RELATED: The How-To Geek Guide to Measuring Your Energy Use Don’t neglect to include the power load of peripherals when calculating your needs. In the case of a power outage where you’re working at the computer, it’s worthwhile to have the battery also supply the monitor so you can interact with the machine. On the other hand, our two computers (in the home office and the playroom) do have peripherals like monitors, external hard drives, and so on. In the case of our home server, we don’t need to calculate the peripheral load because there are no peripherals (it’s a headless server with no power needs beyond that of the hardware directly in the tower). ![]() So how can you calculate the power needs of the system? The first step is examining the core system and peripherals you wish to keep on in the event of power loss. If your UPS unit doesn’t have enough juice to provide for the system from the moment the power cuts out until the moment it has successfully shut down, you’re risking damage to the machine and data loss. At the bare minimum, you need enough juice in your UPS unit to give your computer system adequate time to shut down properly. ![]()
