### ⭐⭐⭐ 3.0 out of 5 stars







  
  
    OK power supply, very basic. Low bang for the buck.
  

*by R***W on Reviewed in the United States on July 20, 2016*

650Va version reviewedWe have several computers at our home office, plus the usual assortment of monitors, accessories, etc. All on UPS's. We're not loyal to any brand - basically be look for the most bang for the buck.  For the power supplies, the bang for the buck on this unit is so-so. We have three Cyberpower UPS in the office - they have been up and running for two years - and have display screens that show all current status, from load to discharge. The Liebert has two LED's - that's it. No idea if it's charging, capacity, time remaining or anything else. When the power fails, like all other UPS, it beeps about once per second. It's actually quieter than many - but there's no way to turn it off.I tried this on a table lamp that uses four 20 watt bulbs - it lasted just under 7 minutes. 80 watts, 7 minutes (longer than the math said it should last.)  That''s not very good. An average computer uses around 140 watts, plus another 20 for the monitor. 160 watts - so you'll have just over three minutes of power.  I have a monster PC that uses 220 watts and THREE monitors - 70 watts. 290 watts. For that PC this is almost useless. For an average home PC, this will last three to five minutes. There is a USB connection and the power supply will automatically shut down the computer (you obviously need an available USB port.)The back of the UPS has one surge protected outlet (white) and three with power backup.  On the upside, there is a two year warranty, but others have three year.I prefer having a LOT more power available than I need, so I can actually use my computer during the power outage.  Having a "time remaining" on the display is a huge benefit for that.  If all you need is a basic power supply that will automatically shut off your PC, this is fine. But there are many in the same price range with more power and features.

I'll start off by saying this UPS was delivered super fast, about 5 days before I expected to receive it.It came well packaged and was super simple to set up. I just pulled it out of the box and plugged it into the wall to let the battery charge. Instructions come in the form of a single sheet of paper with pictures and product specs. It was all very easy to understand.The unit seems sturdy so far. I'm not hearing any humming or buzzing, and the plastic case should be plenty tough for my home office. I'm definitely happy with this purchase!

    Disappointing product from former leader in UPS technology!
  

*by B***N on Reviewed in the United States on February 27, 2013*

I ordered two of these units because I was familiar with Liebert's datacenter power systems and I have had bad experiences with APC and TrippLite units I've purchased for organizations I've worked for. Just after the warranty expired, one of the units failed completely and the second began emitting a loud, continuous beep (after a year in the same location, with the same load on it). I ordered replacement batteries, thinking that was the problem - to no avail. I replaced both units with ones from PowerWare, which I had limited, but good experience with in the past. After a year in service, the PowerWare units are still going strong and I have started standardizing all of our UPS systems on PowerWare.
