Cyberpower CP900EPFCLCD-UK Backup UPS PFC Pure Sinewave 900VA/540W 2 x UK Sockets 4 x IEC

Power outages don’t happen very often but when they do I no longer need to worry about my PC?Anything from 15minutes to safely shut down the computer all the way to 220 minutes.More than enough time.

Purchased 2 years ago and has been quietly doing its job, has saved me from power black outs with my pc running long enough for me to shut it down with out any problems, and thanks to the USB on the front allowed me to charge my phone while I had no power... was absolutely chuffed with the unit, much better than the cheap thing I had before... Up until today, on my last self test it started showing an F02 error, it recommends reducing the load. I unplugged the additional non battery supplied side (extra monitor etc) and powered it back on, it went very bang, big baddabomb, and the whiff and sight of the magic blue smoke appeared.. I have unplugged it from my set up now... it still powers on, but directly to the error screen, but after the bang and smoke I will not be using it anymore.. time to see if there is anything I can do via cyber power themselves else its a lot of money for only 2 years of service.

This UPS (now I have 3 of them), has been working really well and the other two have been working well for about 2 years now. It's still too early to say how Long they will last. In my experience, generally most UPS, starts to have some issues after 4 years of continuous use, so it will take way longer than 2 years to be able to say how robust these are.As a general advice, the way I calculate how good UPS are, is by dividing their price over the number of years of reliable activity (reliable!), the cheaper it gets per single year of activity the better is the UPS.Hope this helps

After talking with the company they recommend this unit, it was purchased to keep the modem phone and by pon fibre optic cable unit powered during power cutsNot had to test the unit yetThe build quality is great and instruction excellent it’s easy to set up,Just hoping that it will not be needed just purchased as a backupThe company is excellent to contact and came back to me very quickly with answers to all my questionsI would definitely recommend and I am thinking about getting another unit for some other equipment that I have

This UPS looks like it will do the trick for me. The delivery was several days quicker than advertised which was great. The item is as described and looks exactly like the pictures.Delivering things like UPS to northern ireland seems to be a problem, looks like there is some regulations about batteries. Amazon will not ship it's own brand UPSs to NI. So was good to find this company.I have not rated the battery life as it is too early to tell, but if it meets the spec it will be all I need.

I have suffered from enough short power outages to make UPS essential for my computer. A few days back a power cut revealed that my old UPS had died without warning me (though lack of care on my part may have contributed)! I have a high end desktop with two screens, and I may reorganise my system to bring more components together, so I looked for something with a higher output wattage and battery life than the basic single computer UPS's. Cyberpower CP1500EPFCLCD-UK seems to meet these requirements and is currently running fine. The free management software downloaded from the manufacturer's Website seems fine and allows you to set options such as time before automatic shutdown with ease. I set the shutdown type option to "Hibernate" and the trigger to "shut down when remaining battery life 5 mins or less", pulled out the mains plug, and waited. In due course the computer shut down safely, as intended, so excellent!However, and my reason for a 4* rating, is that when I plugged the mains in and started my computer again, it shut down again straight away. Clearly this would not have happened if I had left the UPS to charge for a while but if I had been in a hurry to get back on-line this would have been a pain.The alternative is to set the maximum period allowed running under battery power before auto shutdown but that seems to make less use of the battery capacity and there seems to be no way to use the two settings together - I would like to set it to run for 20 minutes provided that at least 5 minutes run time remains. Manufacturer????Observation, but not really a problem: When first connected as directed, the battery charge showed as 100%. Just to check that it worked, I pulled out the mains plug from the UPS and waited. My computer showed no sign of any issues, as I had hoped! However the battery charge as shown by the manufacturers software dropped rapidly to about 60% and was shown as recharging from that level when I put the plug back. It is my impression that to be sure of getting the battery fully charged, it should be run down a little before the system is used in anger.As someone has mentioned, getting replacement batteries may be an issue. UK Amazon currently lists the correct batteries (RB1280X2B) but shows no one in the UK with any in stock or expecting them in. I have not looked further but, if replacement batteries are a concern, then it might be worth checking their availability in more detail.

I now run two of these, main computers on one and support hardware (NAS's, cable modem, MESH system, office lighting on the other). It was too much gear for the one unit I bought a couple of years ago so the easiest solution for me was to just buy a second. They've lasted well but the batteries will need replacing eventually, not sure exactly how long they last - maybe 3years? Whatever, they definitely work because we regularly get power cuts and brown-outs here because of poor quality infrastructure - power cables run through trees and every time there's a strong wind the power goes out.
