The APC Back-UPS 650 enables you to work through minor power outages and brownouts without interruption or equipment damage. It's ideal for use in small offices or homes and provides protection to PCs, printers, wireless routers, gaming consoles, and more. Because the APC Back-UPS 650 is compact, value-priced, and simple to use, it can be used wherever there are sensitive electronics to be protected.

When the power flickers, the Back-UPS maintains the current so your equipment never feels the disturbance. If the power goes out entirely, the Back-UPS gives you enough time to save your work and shut down in an orderly manner. If the power is out for an extended time, the UPS shuts down automatically.

Eight outlets give you room to plug in several devices. Four outlets provide surge protection only and four provide backup power plus surge protection. The outlets are spaced to accommodate two wall-wart transformer blocks without blocking outlets. The UPS even provides data-line surge protection for your Ethernet connection.

The APC Back-UPS 650 requires no particular expertise to use. It features a maintenance-free, sealed lead acid battery that's easily replaceable. LEDs show you the status of the UPS and line power at a glance, plus the UPS sounds an alarm whenever there's a problem either with your line power or with the UPS itself. A simple push button resets the unit after a power problem. UPS management is accessible through a USB port.
