    Very easy to setup. Controls computer to shutdown before battery fails. PowerChute program provides all the information you will need and it's very easy to use.

    Compact and reliable UPS system with nice software

    Nice, compact uninterruptable power supply that works great with the PowerChute software which tests the battery and protects during brown-outs. The device will run my computer and a 27" monitor for 10-15 minutes if there is a total power outage which is what I need to keep things running. Having a replaceable battery makes keeping this thing running for years super easy. Highly recommend it as it is small enough to fit under a desk or in a smaller corner of a room.

    I was unsure of which product was best to rep;ace my existing battery surge protector, which had shown a problem. This suggestion was perfect for my needs.

    This backup saved us when we had a power surge. Everything that was plugged in was protected. Huge savings for us! Great when power goes out I know that I can still work.

    I've always trusted APC. Used their bigger stuff in data centers for years. This one hooks up to your computer and will tell it to shut down if the power goes out.

    Great Ups For entertaniment center

    Apc is my go to for my surge and UPS needs. I have 5 APC battery backups including this one and they all have been great products. This one was no exception. The only negative is that the outlets are tamper protected and it's a little difficult to plug a device in, which if your electrical outlet is a gfci or some protected circuit you can trip the protection trying to plug something in. This was not a big deal as long as you can reset the gfci easily at the outlet with the reset button. This was troublesome for me as my outlet was behind everything. Other the that a flawless solution.

    I have used other brands before but this time when my battery backup stopped working I went back to APC. It was simple to set up and I like the new sleeker design.
