Wife got this for me for xmas - works great. I have a few of these Cyberpower units, this specific one backs up up my primary gaming / multimedia rig. It's dead silent, and so far haven't had a hiccup at all. Only one or two power blips here, but it kept everything up nice and smooth. Pure Sine wave is a plus.

I've got a few different cyberpower rack ups's and have zero trouble with them of the past couple years. This one is no exception so far. I didn't need very much runtime and just needed a rack unit that was easy on the budget, getting a 1500/900 2U line-interactive/AVR at this low cost is hard to beat..

I'm in IT and have purchased 50-60 of these units in the last 3 years with no problems. No DOA's and non have failed yet. I find that 550VA is great for single workstations like Core2Duo with duel 19" LCD's.

Just a great product. I was debating between this and the Tripplite. I am very happy I went with APC. The product is very well made and the cloud as well as local interface to the unit is excellent. I was worried before delivery about given its short chassis how it would handle in the rack using only the front rails and the came up with a really nice brace for under the unit that fits securely and easily handles the weight of the unit. It is also dead silent which for me is a must as it is within my office and quiet matters.
