Product Features
Technical Overview
This line-interactive UPS operates on a single-phase power system with a stepped approximated sine wave output, suitable for most computers, networking gear, and monitors. The AVR circuitry actively corrects undervoltage and overvoltage conditions, maintaining stable output between 120V ± 8% without draining the battery. The 850VA capacity supports a maximum load of 510 watts, with a full-load runtime of two minutes, providing enough time for safe shutdowns or to ride through brief interruptions.
Key technical specifications include a 6-foot NEMA 5-15P power cord, 15A input current, and 1103 joules of surge energy rating for robust protection against spikes. The lead-acid battery is user-replaceable (RBC17 sold separately), allowing easy maintenance without professional service. The UPS also includes 1GB network data line protection to safeguard connected Ethernet equipment from surges, ensuring comprehensive coverage for both power and data lines.
Key Product Advantages
The Back-UPS Pro BX850M stands out with its combination of compact design, clear status monitoring, and robust protection features. The LCD display offers immediate visibility into load levels, battery health, and runtime estimates, reducing guesswork during power events. Automatic voltage regulation ensures consistent power quality, which can prevent hardware stress and data corruption caused by brownouts or overvoltage.
Compact Tower Form Factor
Measuring 7.48" H x 3.58" W x 12.20" D, this UPS fits seamlessly into office environments without occupying excessive desk or floor space. The tower orientation allows for stable placement and easy access to all outlets.
- Footprint optimized for under-desk use
- Black finish blends with most office decor
- Lightweight at under 15 pounds for easy relocation
Comprehensive Outlet Configuration
With eight total outlets—four with battery backup and surge protection plus four surge-only—this unit provides dedicated power paths for critical equipment and less essential peripherals. This separation helps maximize backup runtime for priority devices.
- NEMA 5-15R outlets standard in North America
- Clear labeling distinguishes battery-backed outlets
- Surge-only outlets ideal for printers or chargers
Deployment / Use Cases
This 850VA UPS is ideal for protecting small to medium business workstations, networking equipment, and point-of-sale systems where reliable uptime is essential. Its capacity can typically support a desktop computer, monitor, and networking switch simultaneously, providing enough runtime for orderly shutdowns during extended outages.
Common deployment scenarios include office desktops, retail cash registers, home office setups, and network infrastructure nodes. The compact tower form factor makes it suitable for environments where rack space isn't available or where equipment is distributed across multiple locations. The 12-hour recharge time ensures the unit is ready for subsequent power events relatively quickly, while the user-replaceable battery design simplifies long-term maintenance.
Small Business Workstation Protection
Perfect for individual workstations running accounting software, CRM systems, or design applications where unexpected shutdowns could result in data loss or workflow disruption.
- Protects against data corruption during brownouts
- Provides time to save work and shut down properly
- AVR maintains stable voltage for sensitive electronics
Network Edge Device Support
Well-suited for routers, switches, and VoIP phones at remote offices or retail locations where power quality may be inconsistent but network continuity is critical.
- 1GB data line protection safeguards Ethernet connections
- Compact size fits in network closets or behind counters
- LCD shows status without needing management software
Physical Profile

FAQ
What is the power capacity of the APC BX850M UPS?
The APC Back-UPS Pro BX850M provides 850 volt-amps (VA) of capacity, which translates to 510 watts of maximum supported load. This capacity is suitable for protecting typical desktop workstations, monitors, and networking equipment, offering enough power for orderly shutdowns during outages.
How long will this UPS run on battery power?
At full load (510 watts), the BX850M provides approximately 2 minutes of runtime. Runtime increases significantly with lighter loads—for example, it can support a typical desktop and monitor for 10-20 minutes depending on their actual power consumption. The LCD display shows estimated runtime based on current load.
How many devices can I connect to this UPS?
This UPS has eight NEMA 5-15R outlets. Four outlets provide both battery backup and surge protection for critical equipment like computers and networking gear. The remaining four outlets offer surge protection only, suitable for peripherals like printers or chargers that don't need battery backup.
What does automatic voltage regulation (AVR) do?
AVR corrects minor voltage fluctuations (brownouts and overvoltage) without switching to battery power. This extends battery life and provides cleaner power to connected equipment. The AVR in the BX850M maintains output voltage within 120V ± 8% during input variations, preventing hardware stress and data corruption.
Can I replace the battery myself?
Yes, the lead-acid battery is user-replaceable. The compatible replacement battery is the APC RBC17 (sold separately). Replacement involves removing a panel on the unit and swapping the battery, with instructions provided in the user manual. This design eliminates the need for professional service calls.
What type of warranty does this UPS include?
The APC Back-UPS Pro BX850M comes with a 3-year warranty on the UPS unit itself and a 1-year warranty on the included battery. This warranty covers defects in materials and workmanship, with additional details available in the product documentation. The unit is also Energy Star certified and complies with RoHS and REACH environmental standards.
What power capacity is listed for this UPS?
The listed power specification is 850 VA, which helps position the unit for the right load level and installation role.
How many outlets are available?
The product includes 8, which helps buyers understand how many connected devices it can support in its intended deployment.
