The CyberPower CP685AVRG is a compact line-interactive UPS that keeps a desktop, workstation, router, or retro PC alive long enough for a graceful shutdown when the utility power drops. Rated at 685VA/390W, it uses simulated sine wave output plus Automatic Voltage Regulation, so minor brownouts and sags get corrected internally instead of draining the battery - a meaningful detail if your wall power is noisy and you want the cells to last. Eight NEMA 5-15R outlets split evenly: four give you battery backup plus surge protection, four are surge-only for printers, lamps, and other gear that…

Frequently Asked Questions
How many outlets get battery backup?
Four of the eight NEMA 5-15R outlets are battery backup and surge protected. The other four are surge protected only, so plug printers, speakers, and lamps into those and save the backed-up bank for your PC and router.
Can the CP685AVRG run a gaming PC?
It is rated 685VA/390W, so it suits desktops, workstations, networking gear, and home entertainment equipment. A high-wattage gaming build with a large GPU can exceed 390W under load - add up your components before committing.
What is AVR and why does it matter?
Automatic Voltage Regulation corrects minor power fluctuations without switching to battery power. That means brownouts and sags get handled by the UPS circuitry instead of cycling the cells, which extends battery life.
Does the warranty cover the battery?
CyberPower lists a 3-year warranty that explicitly includes the batteries, along with a $125,000 connected equipment guarantee. Check the product listing for current warranty terms and claim requirements in your region.
How long will it power my equipment during an outage?
CyberPower positions this unit as having enough runtime to perform a graceful shutdown and protect against data loss, rather than extended operation. Actual minutes depend on your connected load against the 390W ceiling.
Is this UPS safety certified?
Yes. CyberPower states the CP685AVRG was tested in a UL certified lab and is listed with UL as meeting or exceeding safety standards. LED status lights also indicate power-on state and wiring faults.
