CyberPower CP850PFCLCD PFC Sinewave UPS System - Reliable AVR Backup

Our review of the CyberPower CP850PFCLCD finds it best suited for desktop computers, workstations, and home networks that require an active PFC compatible backup. The single biggest reason to buy is its PFC sine wave output combined with Automatic Voltage Regulation, which means sensitive systems that use active PFC power supplies get clean power and fewer unnecessary battery swaps. For anyone who needs compact, dependable battery backup and surge protection in a mini-tower footprint, this UPS delivers practical protection without complexity.

Key Features

• PFC Sinewave Output: Provides a clean sine wave output that is compatible with active PFC power supplies, reducing the risk of instability on modern desktops and workstations.
• Automatic Voltage Regulation (AVR): Corrects minor brownouts and overvoltages without switching to battery, which helps extend battery life and keeps equipment running through common line fluctuations.
• Battery Backup: Offers full battery backup for connected devices during outages, allowing safe shutdown of computers and network gear to prevent data loss.
• Surge Protection: Built-in surge protection shields connected electronics from transient spikes and lightning-related surges in typical home or office environments.
• Compact Mini-Tower Design: Saves desk and floor space while providing ten outlets to protect multiple devices in a small footprint.

Who It's For

The CP850PFCLCD is ideal for users running desktop PCs with active power factor correction, small office workstations, home entertainment systems, and network gear that need a reliable clean power source and protection from frequent voltage fluctuations. Its compact mini-tower shape fits well beside a desk or in a small equipment closet.

It is less appropriate for large server racks or environments requiring very high wattage or extended runtime; those users should consider larger capacity UPS models or rackmount solutions. Users needing long runtime for many devices should also look at higher-capacity units.

Pros & Cons

Pros

• Compatible sine wave output supports active PFC systems and reduces compatibility issues with modern power supplies.
• AVR corrects small voltage swings without using battery, preserving runtime for actual outages.
• Ten outlets provide a practical number of protected connections for a home or small office setup.
• Three-year warranty and a substantial connected equipment guarantee add confidence for valuable devices.

Cons

• Runtime and capacity are limited to 850VA/510W, so it is not meant for large servers or long-run backup scenarios.
• Mini-tower format may not fit rackmount needs without additional hardware or adapters.
