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

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!

been using this for a while now and its worked flawlessly, lasts a good amount of time (around 30 mins with 40% load) and allows me to keep going with the odd power blip. very easy setup.

Neat, with excellent display that can be turned off/on that can display various parameters and settings that are adjustable. Is virtually silent when operating.

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.

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.
