Cyberpower CP1500EPFCLCD-UK Backup UPS PFC Pure Sinewave 1500VA/900W 2 x UK Sockets 4 x IEC

Bought this to replace a very old UPS that died. Needed to power a desktop PC, NAS and associated bits and pieces. Seems like a very competent piece of kit. Currently using about 10% of available power, which gives me an estimated 60 minutes or so run time if the AC power fails. The UPS has 6 backed up power sockets, 2 x UK 13A sockets and 4 for IEC C13 leads. Power to these is surge protected against mains spikes, and changeover is instant if the mains fails or falls outside voltage and frequency parameters that you can alter to be more or less strict. It is a pure sine wave unit, which should ensure that the powered equipment won't be affected when running on battery. During normal running once the batteries are charged the unit operates in passthrough mode, which basically just supplies mains to the outlets, so it is very efficient in normal use. The associated Powerpanel personal app lets you view and manage the parameters for the Cyberpower unit, and initiate a controlled shutdown of the device that it is connected to via USB. There is also a Powerpanel cloud function which lets you control the UPS from any device via the cloud but that is a chargeable extra. I have not investigated that. The unit has been in use for a couple of weeks now, with no problems detected. I have tested it by using its built-in self test, and also by simply unplugging the source mains to simulate a failure and all the connected kit continued working as if nothing had happened. It is a bit pricy compared to some UPS units but has a large capacity and is easy to set up and operate.

I bought 2 of these, one for my main PC+router+TV and another for my unRAID server, they work great and had them 2.5 years You can plug in the USB cable from the UPS into the unRAID server and it will automatically identify it and work out-of-the box, no software install required! In the unRAID OS settings you can then configure what % to shutdown the server safely etc I've had a few unexpected power cuts in my house lasting 10 minutes or so and this power backup handled it just as expected, zero downtime or interruption. Best way to avoid data corruption! When I have my annual electric inspection I let the guy just flip the main breaker without worrying about turning off my PC or server One of the devices is at the bottom of my bed and it's silent. Very rarely it will do some clicking noise for a few seconds but that's just a part of it's operation and not an issue The only downside is that it uses lead acid batteries which are recommended to replace after 3-5 years due to reduced charge Excluding age, lead acid batteries will get 200-500 cycles on average before becoming an issue, where as Li-ion is 1k-2k, LiFePO₄ 2k-5k So for my next UPS I will look for LiFePO₄ as the lifecyle is 8-12 years vs 3-5y lead acid or I might try and retrofit LiFePO₄ batteries into this UPS when the time comes

What was delivered was the newer CP1600EPFCLCDUK. This is a newer product. Works great alongside the other 1500VA models I have. Only snag is the buttons are in a different position on the front panel.

This is a pretty good UPS. I have had no problems with it and the shutdown software works as described. A big attraction of this UPS is that has a mix of UK 3 pin square sockets and IEE power sockets - which is very handy for those items for which you can't readily get an IEE cable. One other point worth noting is that, initially, I had some doubts about the fact that it only appeared to have RJ45 sockets for surge protection on the broadband line - one in and one out - rather than the RJ11 sockets that the broadband wall socket and router and my previous Belkin UPS use. What I hadn't realised is that RJ45 sockets are designed os that their centre connections are exactly the same as the connections on RJ11 sockets - the RJ11 is in effect a subset of the RJ45 - so you can plug an RJ11 cable into an RJ45 socket, as long as you centre it in the RJ45 socket so it connects with that subset of connections. Once I realised this (helped by Cyberpower's technical support, who helpfully sent me a diagram and instructions) I was able to plug in my existing RJ11 cables and everything worked well. I later purchased some new cables with RJ11 at one end and RJ45 at the other, so I was able to plug in the RJ45 ends to the UPS and the RJ11 ends to the wall socket and router - because the RJ45 into an RJ45 socket seems physically a more secure fit than the RJ11 into an RJ45 socket. But when you see the sockets described as RJ11/RJ45, that is what it means. The only other thing to note is that, if you do use these sockets for surge protection, they will adversely impact your broadband speed. Mine was reduced from about 48-50 Mbps to about 32 Mbps. I contacted Cyberpowerr about this and they said it is a feature of surge protection and that they are working on an update which might improve matters - but that the update won't be free. To investigate furrther, I also checked broadband speeds with and without the surge protection offerd by an ageing Belkin UPS - and the Belkin UPS reduced the speed to about 43 Mbps, not quite as bad as the Cyberpopwer UPS but it tends to confirm the general point that surge protection does adversely impact broadband speeds; and Cyberpower's surge protection does seem to be worse than some others in this respect. That is why I have deducted one star from what would otherwise have been a five star review.

So glad I bought this when I got my custom built PC. Recently had a city wide power serge and this saved my £3K gaming and editing PC. So easy to set up very plug and play attached my pc to it and it worked instantly with a very quiet even when it detects a power outage or power serge. I have opted to put device into silent alarm feature as the alarm can be quiet loud which is good if you have headphones on and gives you an opportunity to safely shut down your device. However for me the audible click as it switches over is enough when I have needed to shut my device down. Morel of the story spend the money now to save you paying out in the future

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.

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.

We live in a normal urban street but lose mains power regularly. Sometimes it may be due to storms, but I think the local substation is just running on the edge. I got the Cyberpower UPS because I play online video games. It does the job nicely, running everything for 50 mins plus when the power goes out. Can also run our router and wifi for a couple of hours if the PC isn't on. Controls and display were not totally intuitive but easy enough to figure out with the manual. It's heavy but not too bulky. Very satisfied.
