APC Back-UPS Pro Compact 850VA Battery Backup UPS

The APC BX850M is an uninterruptible power supply in a tower style design that provides 850VA or 510W of battery backup and surge protection for computers, wireless routers, and other essential electronics in a home office or small business.

This Back-UPS Pro model offers eight outlets. Four outlets supply both battery backup and surge protection so key devices keep running during an outage, while the remaining four handle surge protection for peripherals that do not need battery power. Built-in Automatic Voltage Regulation corrects high or low voltage conditions on the fly, letting connected equipment receive stable power without drawing on the battery until it is truly needed. A dedicated 1Gb network dataline port shields Ethernet connections from harmful surges that can travel through cables.

The front LCD screen presents real-time information such as battery charge, load level, and estimated runtime, so you always know how much backup capacity remains. When an outage lasts longer than the battery can support, the included PowerChute software executes a controlled shutdown to prevent data loss and file corruption.

The internal battery is sealed and maintenance free, yet it is also user replaceable, allowing you to refresh the UPS without specialized tools. ENERGY STAR certification keeps daily operating costs low, and a three year limited warranty underscores APC quality.

Whether you are working from home and need your modem and VoIP phone to stay online, managing a small retail point of sale that must finish transactions, or gaming and want time to save progress, the APC BX850M fits easily under a desk or on a shelf and delivers the dependable power protection you need.
