I've been buying these for years for office pc's. They give plenty of time for a controlled shutdown during power outages.

Great protection, great price

on 5/18/2010

Our lights flicker a handful of times during the summer months. At this price, you can't afford not to get this over a standard surge protector. I ordered 5 of these for the office after similar success with Cyberpower's larger units. I ordered them Monday afternoon w/ the free 7-10 budget shipping and received them the NEXT DAY! comes through again!

owned for 5 years and it's still good

by bryan on 6/30/2010

The version I bought that looked very much like this worked for 5 years and is connected via USB and works simply and reliably. I'm buying another unit for wireless router and cable modem. It far exceeds the life expectancy I've seen with APC units in Florida.

Product Overview

The CyberPower CP550SLG Standby uninterruptible power supply (UPS) safeguards home/office computers and other electronics (monitors, scanners, speakers, CD/DVD players, MP3 players and phones) from surges, spikes, sags, brownouts and other power abnormalities. Its composite integrated circuitry offers advanced lightning protection.

Patented GreenPower UPS™ technology used in the CP550SLG reduces energy-usage and cooling costs associated with UPS power protection. As a result, you can expect to save up to $9 annually (varies based on usage and regional kilowatt per hour costs) by using GreenPower UPS technology.

The CP550SLG includes PowerPanel Personal Edition UPS management software which monitors the vitals of the UPS and will safely shutdown your system in case of a power outage.

This rugged unit is equipped with a RJ11 port which protects against surges from phone or network disruptions. The small footprint design is ideal for horizontal or vertical placement, and is even wall mountable.

PowerPanel is quickly and easily installed on any Windows-based PC and is designed to utilize minimal system resources. Diagnostic screens give immediate visuals of the UPS’s status, and also include the following features: Silent operation mode, configurable system notifications, automatic self tests, adjustable high/low voltage warnings, event/data logging, and scheduled shutdowns.
