CyberPower AVRG900U AVR Series 900VA 480W Desktop UPS with AVR and USB

A compact UPS with line interactive topology, the CyberPower AVRG900U provides battery backup (using simulated sine wave output) and surge protection for desktop computers, workstations, networking devices, and home entertainment systems. The AVRG900U uses Automatic Voltage Regulation (AVR) to correct minor power fluctuations without switching to battery power, which extends battery life. AVR is essential in areas where power fluctuations occur frequently. The AVRG900U comes with a three-year warranty (including coverage of batteries) and a $200,000 Connected Equipment Guarantee.
