The CyberPower CP900AVR is a 900VA/560W line-interactive UPS built to keep a desktop, workstation, or retro PC alive through brownouts and short outages. Ten NEMA 5-15R outlets split the load: five give you battery backup plus surge protection for the tower, monitor, and network gear, while five more handle surge-only duty for printers and speakers. Automatic Voltage Regulation is the reason to pick this CyberPower over a plain surge strip. AVR corrects minor sags and swells without draining the battery, so the cells cycle less and last longer, which matters if your line voltage wanders…

Frequently Asked Questions

How much equipment can the CP900AVR actually run?

It is rated 900VA/560W. Keep the combined draw of everything on the five battery-backed outlets under 560 watts, which typically covers a desktop tower, a monitor, and a router or modem.

Will this work with a gaming PC that has an active-PFC power supply?

The CP900AVR outputs simulated sine wave, which some active-PFC supplies reject on battery transfer. Check your PSU documentation, or choose a pure sine wave model if it requires one.

Do all 10 outlets provide battery backup?

No. Five NEMA 5-15R outlets are battery backup plus surge protected; the other five are surge protected only. Put your PC and network gear on the battery side and printers or speakers on the surge-only side.

What does the warranty cover and for how long?

CyberPower provides a three-year warranty that includes the battery itself, plus a $300,000 Connected Equipment Guarantee for devices damaged by a surge. Check the product listing for current terms and claim requirements.

What is AVR and why does it matter?

Automatic Voltage Regulation corrects minor over- and under-voltage conditions using the transformer instead of switching to battery. Fewer battery cycles means longer battery life, which matters most where line voltage fluctuates often.
