Use the watt rating, not just VA
This exact U.S. model is rated 1000 VA and 600 W. Add the connected equipment's actual watts and leave margin; VA is a separate apparent-power rating. The rating does not predict runtime, which varies with load and battery condition.
Assign the six backed outlets deliberately
The manufacturer datasheet separates six battery-backed outlets from four surge-only outlets. Reserve backed outlets for the computer, display, and network equipment that need time to save work or remain connected; surge-only outlets do not provide battery during an outage.
Sine output and transfer still need device checks
APC specifies sine-wave output on battery and transfer of up to 8 ms in the manual. Neither fact guarantees compatibility with every power supply or successful ride-through. Follow the connected equipment maker's requirements and test your own shutdown behavior before relying on it.
Plan for replacement and shutdown
APC names APCRBC160 as the replacement battery and specifies 16 hours typical recharge. The manual says Windows users can use PowerChute Personal Edition; Mac users should use the operating system's native shutdown features. Confirm current software availability and battery service instructions with APC.
