I purchased this UPS to isolate my computers and network disk drives from the AC line in a home office. The unit has worked well for that purpose. It has not had to engage too many times since I installed it, but it has seemed to do the job when it did. I chose this unit because I wanted a UPS that puts out a real sign wave AC waveform when it goes to battery operation. Most home office units put out more like a square wave (cheaper to produce) that does not work well with some modern computer power supplies that are power factor corrected. It fits neatly under my computer table, and shows basic functioning on the front panel. There is also software (both a personal edition and a business addition with more features) that runs on a computer connected through a USB or serial port. This software has very useful information including how much power is being drawn through the unit (on line or battery power), voltage, etc. as well as a history of actions taken. The only issue I found, and it is minor, is that my computer had trouble recognizing the connected UPS when interfaced through a USB hub. I talked to the manufacturer, who was very responsive, and told me it works better when plugged into a direct USB port on the computer. I tried that, and it has worked for me. The total load in my office is normally only about 300 watts as reported by the UPS, so it will power my office on batteries for more than 30 minutes--which almost always outlasts any power outage I experience. The software can be configured to notify the attached computer of a power failure (batteries engaged) and have it shut down the computer when the batteries get below a certain level. I have not had time to try this feature. There are also several test modes that can be accessed through the software to verify operation, for example, by simulating a power failure. I found this very useful to give me confidence in the unit. I am not sure what else to say. It provides sign wave backup AC at a reasonable price.

Luckily I use this mostly for one desktop computer, which get almost 45 Minutes of battery life. The only noticeable problem thus far is when another computer is powered through it the fan comes on, constantly. Once it hits 40% load the fan just runs, period. This is a compromise: beefy UPS, or quiet one? It isn't bad, just annoying since it is next to my desk. And I wouldn't want it to be running like this for years, since I doubt the fan will last very long if it runs constantly.

This was significantly cheaper then other options and I have no complaints as of yet. I found that my Dell Computer and Samsung Plasma TV both required True/Pure Sinewave UPS's after having many many problems with by regular APC UPS's that I bought at Best Buy. I found this and find it to work very well.

I had a lot of power problems in my room as I live in an older house and I haven't had anything shut off with a breaker trip or brown out since upgrading to this.

Previously I had my servers hooked up to Tripp Lite UPS; I had nine of those, but they began failling one by one. I currently have this CyberPower Sinewave UPS hooked up to a Dell server and a ReadyNAS at my dental office. The servers have critical accounts database. I've had several brown-outs last year when our power company (SRP) was having some troubles in the area. Also a few blackouts during thunder storms in the summer in Phoenix. My servers have had no troubles reported; everything was running smoothly during the outages. I also had a handyman cause a short when he was fiddling with an outlet. That burned out a network switch and one of my surge protectors; literally smoke coming out of that surge protector. I got him out of the office right away but anyways, no problems on the servers connected to this UPS.
