Power for workstations and networking

The APC Back-UPS BE850G2 delivers 850 VA and 450 W of battery backup to desktop computers, wireless routers and gaming consoles. It keeps a typical workstation running through brief outages and powers networking gear for hours so internet access stays alive. Home offices and small businesses gain continuous operation during voltage dips and blackouts.

Stepped sine wave and limited runtime

The unit produces a stepped approximated sine wave at 120 V, which suits most switching power supplies but may not meet the needs of sensitive medical or laboratory equipment. At full 450 W load the battery lasts only 2 minutes, enough for a controlled shutdown but not for extended work. Recharging takes 8 hours, and the input window is 92 to 139 V with auto-sensing 50/60 Hz frequency.

Tower form with wall-mount option and spaced outlets

A lead-acid battery replaceable with the RBC17 cartridge sits inside a tower chassis that includes keyhole sockets for wall mounting in tight spaces. Nine NEMA 5-15R outlets are split between six battery-backed and three surge-only ports, spaced to accept transformer blocks without crowding. Two USB ports supply up to 1.5 A for phone or tablet charging while the UPS is on utility or battery power. Surge protection is rated at 354 Joules.

Questions about this item

How do I choose between the battery-backup and surge-only outlets on this BE850G2?

Plug critical gear such as a PC, router or modem into the six NEMA 5-15R battery-backup outlets so they stay running during an outage; use the three surge-only NEMA 5-15R outlets for printers, speakers or other devices that can lose power safely.

What does the 450 W rating mean for my actual equipment?

The 450 W limit is the maximum real power the UPS can deliver on battery; at that full load the unit provides about two minutes of runtime, giving you time to save work and shut down gracefully.

What does the USB interface on this UPS actually do?

The USB port supplies up to 1.5 A for charging phones or tablets whether the UPS is on mains or battery power, and it also enables management software to monitor status and trigger automatic shutdowns.
