Power outages and voltage spikes can shut down your computer, router or media box in an instant. When that happens you can lose work, miss an important video call, or damage expensive equipment. The APC Back-UPS PRO BR900MI 900VA USB Line-Interactive Tower gives you a reliable battery backup and surge protection so your devices stay on long enough to save your work and shut down safely.
APC Back-UPS PRO BR900MI 900VA USB Line-Interactive Tower with APC
You need a safety net for the electronics you rely on every day. This UPS is a compact tower that plugs into the wall and supplies emergency power to up to six devices. It also smooths out voltage spikes so your gear is never exposed to dangerous surges. If the power fails, the built-in battery kicks in and the USB connection can tell your computer to shut down cleanly before the battery runs out.
Usages
The tower works well in a home office where a PC, monitor and router need protection. It is also ideal for a small business server or NAS that must stay online during short outages. Gamers can keep their consoles and internet box running, and families can protect TVs and streaming devices. Anywhere you have important electronics that cannot afford a sudden shutdown, this UPS fits the job.
