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

Living in a village in Rural Cambridgeshire where power cuts & brown outs seem to be relatively frequent, I decided to invest in a couple of these to protect some of my electronic devices from damage and to run them during an outage. I chose this particular model (the 900VA/1500w variant) because it's made by a reputable company, looks good, puts out enough power and the power through its inverter is Pure Sine Wave (rather than Modified Sine Wave which some electronic devices don't like running from) As a UPS novice, this was my first venture into a device of its type. I bought a couple of IEC multi socket plugs and plug all of the following things into one of the units which is in my living room: - Samsung 46" LED Smart TV - 2TB Sky+ HD Box - HP Envy 120 Inkjet Printer - Samsung Surround System System & Sub - Home Energy Monitor - Virgin Media Superb 2AC Cable Router - Panasonic DECT phone base station - Netgear Arlo CCTV Wireless base station The display on the UPS will tell you the draw of all connected devices, and expected run time. I pulled the plug on the UPS to test how it switches from mains to battery power and there was no interruption to the power, it was all seamless as if nothing happened - save for a 'beep' from the UPS to alert me to the power outage. The expected run time with all of the above devices on and running was over 2 hours! Impressive. The other I have upstairs with my Mac, 27" monitor, Cordless phone, 2.1 Speakers & camera battery charger plugged into. This will run also for 2 hours in a power cut too. The units themselves run completely silently, look good on display and the bundled 'PowerPanel' software for PC and Mac is good, allowing you to determine what to do in a power cut (i.e. shut the computer down or leave on until the UPS gets to X% of battery life) The units are also smaller than I expected, probably half the size of an average computer tower. Shorter than an A4 piece of paper and only a few cm wide. Two USB sockets on the front too so you can charge your phone during a power cut or power other USB devices. Batteries are replaceable so if in 5 years time they are worn out you don't need to change the entire unit. I wouldn't hesitate to buy another of these if I had the need to. Very pleased. I only wish there was a way of plugging my combi boiler into one of these so we can have heating and hot water during a power cut! Photos attached.

I bought this CyberPower CP1500EPFCLCD to protect audio/video equipment in my lounge. It met my specific critical requirements exactly, which my previous UPS equipment (Trust and APC) did not. I had tried an APC unit (which was about 50% more expensive) but it generated excessively high levels of noise for use in a lounge. (May 2021 update. Just brought another one to power my 4 servers, Wi-Fi network and computer equipment 24/7. Very reliable with excellent shut-down features. It properly shuts down each server and main computer to avoid data loss. Now have two of these UPS to protect me against an unreliable overhead mains supply.) Thes CyberPower UPS are ideal for my demanding application. My equipment includes a Bang & Olufsen music system, Sony Bravia TV, Philips BlueRay, Denon soundbar and sub-woofer, satellite receiver, WD Live media player, WiFi media bridge and various audio and HDMI accessories. My mains supply is erratic; brown-outs, surges and power cuts are frequent. The display indicates that it will support this total load on battery power when fully charged for about 2 hours. And the display shows much other important data such as power loading, input and output voltage etc. The second UPS supports 4 servers, WiFi router and internet bridge, computers, CD writer and digital media recorder. A few days after installation we had a 5-hour power cut. The CyberPower cut-in seamlessly, indicating about 2 hours power available for my equipment which was in stand-by. 2 hours later it switched off as the battery was discharged. During that time, all that could be heard was a very quiet fan - I had cancelled the alarm. Before I installed the CyberPower my expensive B&O loudspeakers would emit very loud (and scary!) low-frequency pops as the power erratically returned. But the CyberPower ensured a clean, safe and silent switch-on. My CyberPower are absolutely silent in normal operation, and automatically regulates my mains to a constant voltage. They includes surge protection and, of course, automatically switches to battery mode when there are power cuts. They then display the output load and remaining back-up time. They output a pure sine wave (unlike many others which produce a digital version of a sine wave without frequency filtering) which ensures the B&O and Denon function without distortion. They also feature Active Power Factor Correction to ensure the audio/video equipment functions for maximum energy saver efficiency. Some of the really important and useful features for me include USB charging ports (which I use to power 5 volt devices such as an HDMI splitter and an optical audio driver – avoiding the need for additional power supplies) and a combination of IEC and UK power sockets. The IEC connectors are essential because their small size allows 4 to be fitted on the back. I use a 2 separate IEC connector strips to power my equipment. Finally, of major importance is the ability to replace batteries, another reason I chose CyberPower. Overall a really good buy – it does exactly what I need, very well indeed.

I bought the 900W model and it works flawlessly, but even 900W is barely enough for my gaming PC alone. My PC currently runs a Sapphire 7900 XTX Nitro+ and a 12900K in a Corsair 1000D case. It's a watercooled PC with 4 large radiators, 30 fans, and a lot of ARBG LEDs. Of course, both the CPU and GPU are overclocked, and when my PC runs at 100% load it draws 900 +/- 50W. So even though this UPS is remarkable, it barely manages to supply my PC at full load. If I had a newer Intel CPU like 13900k or 14900k, I couldn't even use this UPS. I wish Cyberpower made 1200W or higher wattage models in these series, because currently 900W+ UPS units are either outdated, overpriced, or low quality that are available. If Cyberpower wants to advertise their models for gaming PCs, then I think they should definitely consider making higher wattage models because high end gaming PCs are already pushing the 900W model, and I imagine next gen GPUs will draw even more power.

I bought the CyberPower CP1500 UPS back in Jan 2000 and have been using it since for my home server. The UPS seems well build for a plastic case and considering it's quite heavy. The LED screen provides all of the essential information (load, battery status, estimate runtime) and has the option of displaying other information (watts, AC power status, etc) by pressing the display button. During normal operation the display turns off, but the power button remains lit. The UPS has several ports (2 USB A – front, 1 USB B & serial port – rear). The USB B and serial ports are used for communication between the UPS and your device. The instruction manual states that the UPS communicates with the PowerPanel Personal Edition Software, but I’ve not used this software and have relied on built-in UPS software for my server. In the few instances where I’ve intentionally switched of the AC power or had a brief brownout, the UPS kicks in immediately, with no errors reported from the server. The fan hum from the UPS when active is audible, but not to extent of being annoying. The comms link between the UPS and my server works well, with the server shutting down with sufficient runtime remaining. In normal operation the UPS is silent and with the server at idle (6 active dockers, 3 NICs, and 12 NAS HDDs spun up continuously) the status screen indicates a 67 min runtime. When pushed to the max, runtime does drop, but this is still within my safety margin for a clean shutdown. The only issue I’ve had is with the power LED. At some point earlier this year, the LED broke, so unless you press the Display button, its impossible to tell whether the UPS is on. That being said, I work from home and can hear the server fan hum, so I know the UPS is functioning. I may at some point in the future investigate whether the LED can be replaced. I’m pleased with this purchase, so much so, I’ve bought another CP1500 for a backup server.

Needed to upgrade for my PC and for the fact my APC was getting on a bit reaching the 3 year mark. Decided to go for something that appeared to be fit for the job even if it was very expensive. It's already been called into action quite a few times, where I live the power is always having brownouts and blackouts so it's well worth it for piece of mind for several thousands of pounds worth of equipment. The ability to use it without needing to set it up on a PC will be handy to many, as will the USB ports at the front. The screen detailing how many watts your system is drawing at a given moment is very useful too for those who like to know what is going on in the background. When in use it's quiet other than an audible beep every few seconds to let you know it's in use. This can be disabled however. As I say, it is pricey, more than some decent graphics cards or games consoles can be, which is a bit much for something that apparently does nothing for most of the time. The fact I recently had a power cut and didn't realise until the unit told me says a lot considering I was playing Flight Simulator at the time and have everything plugged into it. As for whether it could sustain running for the 25 minutes it claims under heavy load, I'm not sure but I won't be finding out anyway. Even with a higher end system it's rarely above half of what it can handle with the UPS, it really is an item where you get what you pay for. Safe data, safe technology, less interruptions. Plus they made it easy to replace the battery which most companies don't, great for the long run. To sum up, absolutely recommended!

I had to get a UPS because my local mains power kept glitching on and off for a couple of seconds at a time in high winds. So I looked at various options and settled on this unit. I have installed it on my main computer and it runs the computer, three monitors, Logitech 7.1 sound system, V-Studio 100 USB 24-bit audio interface, Behringer X-Touch USB control surface and a couple of USB 3 hubs with no problems. The Power Panel software says that it is only just over 50% load and can keep the system running for about 30 minutes in a power fail if necessary. All good stuff. There is a bit of a niggle though in that the software can be set to auto-shutdown the computer if there is a mains outage, but the maximum time it can be set for is 5 minutes. I would prefer if it gave me a bit more time before shutting it down - say 10 minutes. At the moment I have this feature urned off so I can shut it down as I like. All-in-all a very good unit. I also like the self-test feature in the Power Panel software which can get the UPS to perform a self test which just confirms everything is working well.

Had to return the faulty item to CCL at *my* expense. Still no sign of a hint they'll refund the carriage as stated in their returns policy. The fault, right next to the QC sticker, was that the case had not been assembled correctly, half of the ABS plastic base bulging out exposing the clips supposed to be holding it together. Didn't even bother to switch it on; repacked and sent back. I only found the fault while hunting around for the serial number. I'd asked for a replacement, but they appear to be in the process of just refunding me for the purchase price. The return + insurance cost me £23.99. They've refunded £5. I'll never be dealing with CCL again.

It does exactly what it is designed for, the wattage readout is accurate, the client side software for Windows (I'm using Windows Server 2008 R2) works brilliantly. My only concern is where to purchase replacement batteries in the UK in 2-3 years when the current battery goes bad but apart from that it's a great product. EDIT: I owned this UPS for just over 3 years and then the batteries inside (it has two in a "pack") went bad and needed replacing. My fear that I would be unable to buy a replacement pack came true. I was unable to source one so I had to go with a DIY method of getting two of the same battery and fitting them myself. This didn't work out too good as the ones I bought were only 99% the same and became wedged inside this UPS requiring me to buy an entirely new unit. So just be very careful when you change batteries, if the new one won't fit without a lot of force simply don't use it and look for some other batteries, I literally had to order another UPS at 6x the cost of the replacement batteries as a result.
