Desktop battery backup for networking

The APC BN450M-CA is a 450 VA / 255 W uninterruptible power supply with six surge-protected outlets, four of which provide battery backup. It is designed for home-office users who need to keep a router, modem or NAS running while a connected computer shuts down safely during an outage.

Replaces basic power strips without battery runtime

A standard strip offers surge protection only; this unit adds enough reserve to maintain low-power network gear for over two hours after a PC drawing roughly 180 W has been turned off. The jump is worth it when losing internet access during a blackout disrupts work, security cameras or smart-home hubs.

Sustained load drops backup time to minutes

At a continuous 180 W draw the internal battery lasts about 4.9 minutes, so the unit is not intended to run a gaming PC or workstation through extended outages. Under lighter, typical networking loads the same battery delivers hours of runtime, making it a focused solution for graceful shutdown rather than prolonged operation.

Questions about this item

How much space and weight should I allow for the 7.85 kg BN450M-CA unit?

The UPS weighs 7.85 kg, so place it on a sturdy shelf or floor area that can support that mass and leave a few centimetres of clearance around the vents for airflow.

Which outlets provide battery backup and what is the correct way to connect my PC?

Four of the six outlets deliver battery backup; plug the computer and monitor into those four, while the remaining two are surge-only for accessories such as a printer or speakers.

When will the internal battery need replacement and how long can it run at 180 W?

Expect 4.9 minutes of runtime at a 180 W load; the sealed lead-acid battery typically lasts three to five years before it should be swapped for a compatible replacement cartridge.
