I purchased this for a computer used as a file server. It has an Intel i3 processor, one SSD, and four 4TB hard drives. An app can be downloaded to manage the UPS as well as to see the unit's status. It connects to the computer via a USB port and can shut down the computer when there is a power outage. You can tell it you shut the computer right away, or let it run unit the battery has 5 minutes of power left. The app is easy to use and understand. It can run my server and a 24-inch monitor for about 30 minutes, depending on whether it is idling or not. This is good enough for a typical short outage (where the power would come back in 5 to 10 minutes). Highly recommended.
