Customer Ratings & Reviews

Backs up my server. Love that it has the USB connection to alert the server to shut down safely when power gets low.

Well, we haven't had an outage since purchase, so I can't say how well it does what it's supposed to do, but the battery rating for the price can't be beat, and I don't have any complaints at this point.

I thought this UPS was great at first. It seemed to do what it was supposed to do. I have two of them to help manage the brownouts that we get. However, recently, one of them failed miserably. The power went out and it kicked in for a while. I turned off my connected equipment with no problem. I turned off the beeping alarm and thought that was that. The power came back on and all seemed well. However, one night the battery suported side just went out, everything thing plugged into that side was off. I reset it to turn it on, but wondered why it was off. The power had not gone out! Then it happened again for no reason. Then, we had a brownout, lasted less than 5 seconds. Thing started beeping and everything connected to battery side lost power again. Now the battery side doesn't work unless the unit is plugged in, so I no longer have a UPS. It's been less than two years with this thing. I'm very disappointed and will be looking for a different longer lasting brand.

Great to use for your home computer just in case you have a power outage and need to turn your computer off.

This system is exceptional for a home office with lots of power needs. It is a rugged product with an extensive battery back-up.

Its Square, it's Black it does the job. I use it for my internet. Modem and router. Cyber Power is good stuff.

Slick purchase! Ordered on-line, picked up at Sandy Utah location and reasonably priced.

Total necessity for power outages! Internet doesn't go out on short intermittent outages! YAY!!!!

Works great. Great value considering capability and price

I can't recommend enough having one of these devices on a TV, computer, stereo equipment or any electronics you have.

Bought this to replace one that had a bad battery. Works great.

With all the power outages we had been having, I decided it was time to really protect my elactronics.

During recent storms, I was able to normally shutdown computer during power outages.

This CyberPower back-up system plays well with Synology NAS (there's some nice features available)

Nice backup unit to have when your power goes and you need something to give you a little extra power.

The CyberPower 650VA was ready to go out of the box.

I needed a battery for my desktop and saw this one at BestBuy. I look it over. It had a lot of what I was looking for on it. So I got it. It does a good job for me. But I would like to have a bigger one at sometime.

Haven't had a problem yet and it is used in a harsh, hot and dusty environment. Powers everything great without a complaint.

Bought this to be the ups for my old 300w computer when I purchased another. So far, so good.

I haven't had a power outage so I can't tell how good it really works, but power is transferring though it just fine.
