CyberPower VP700EILCD Value Pro Computer Power Supply, 390 W, 230 V, Black

Got this today for my QNAP TS-251D as we have had at least 1 powercut a week over the last month. Unboxed it, plugged it in then plugged in the qnap, then the usb comms cable between both and all is working well - the Qnap reckons it has about an hours runtime via this UPS which is great. Have tested it multiple times now and NAS keeps running. There is no power lead with the UPS but there is a kettle lead extension...the idea seems to be you use your existing desktop/NAS kettle lead to run the UPS and the supplied extension lead to power the computer off the NAS. Also, FYI, when i unboxed the UPS and wiggled it a little there was a rattle from the inside...however, after taking the front panel off this just seems to be down to some free space around the internal battery (2-3mm either side) so nothing to worry about. No issues and seems to be a nice compact unit. The LCD display is also a nice touch as well as it can show remaining battery (time and percent) as well and input/output consumption.

Bought this to keep my Unraid server up during short power outage blips and to allow graceful shut down during longer power cuts. Gives me around 15 minutes runtime which is ample.... my server is fairly power hungry so was actually pleasantly surprised.Plugged in via USB and Unraid recognised it with no issues and allowed me to configure what I want to happen in the event of a power cut.Nice compact size and looks smart. Great price and gives peace of mind. Would recommend.

So what I was looking for was something to talk to my Synology NAS down from full power to a nice sleeping state- and also to power the main home modem/router for longer - a couple of hours.The nice things about this are that it is plug and play and has an lcd display as well.The USB connection to the Synology NAS - just works with minimal configuration - so the NAS now powers down gracefully in the event of a power failure after 5 minutes - unlike QNAP and Buffalo - have found Synology very sensitive to power blips - so this prevents me having to spend a lengthy amount of time bringing it back online.The LTE/Fixed Wireless Modem - is powered by the UPS - and seems to have 4-5 hours of runtime in a power loss situation ( - a standard modem that doesn't have to power a mast would probably run for much longer)For the size of the battery - this NAS is still fairly tidy and slots into a 4U slim horizontal space - and also runs fairly quiet.So overall all fairly happy with this - would have given it 5 stars if it came with a UK Plug and something like thishttps://www.amazon.co.uk/gp/product/B082VJLJLZ/ref=ppx_yo_dt_b_asin_title_o08_s00?ie=UTF8&psc=1(So that you can seamlessly plug in whatever you need to)

With my two computers and their 27inch monitors attached I have 40 minutes runtime after power failures, fortunately they are far and few between but they are great at stopping brownouts from affecting your devices. They are very easy to set up and the software support team are very helpful.In fact, I liked these so much I now have two, the other protecting my multimedia setup. The TV is too expensive to be destroyed by something as simple as a powersurge.

I had high expectations for this UPS, particularly for it to operate silently. A few of the reviews here indicated it was free of any background noise, which raised my hopes. Unfortunately, my experience didn't align with those expectations. The unit I received worked fine most of the time but occasionally produced a noticeable buzzing sound that was louder than my PC's fan. This intermittent noise, disappearing and reappearing, proved to be quite disruptive in my compact home office setting. On a positive note, the setup process was straightforward, and the front display was user-friendly and clear. It's possible I just received a defective unit. I've since returned it and plan to research other models more thoroughly before making another purchase.

We get a lot of daft little 3-4 second power cuts where I live, often, many of them one after the other. I've already lost a 4TB hard drive from my NAS due to this so I thought I'd better prevent it from happening again.This device does NOT come with a power cable, but anyone who has computer(s) is bound to have about half a dozen spare ones lying around. If not, it's just a standard kettle lead.The outputs aren't regular 3-pin plugs, instead using C13 outputs. This might seem daft but you do get a smaller unit than it would be if there were six fullsize UK plug sockets on the back instead. I had to make a short adapter to plug in the transformer of my BT Home Hub 5 (3-pin socket on one end, C14 connector on the other). I also replaced the plug on my NAS drive with a C14 connector, which then plugged straight into the back of the UPS. I've probably made this sound more complicated than it is. If you know how to wire a standard plug, it's all very straightforward.I have a Synology NAS which, when connected to the UPS with the supplied USB cable, allows the NAS to shut down safely and automatically after either a fixed period of time, or when the UPS battery runs low. In either case, low UPS battery will force the NAS to safely shut down anyway.I only have my Home Hub 5 and NAS connected to the UPS. My phone line is VoIP so with no internet, I have no phone, which would be bad in emergency situations. Using this UPS, the display claims that it will support both devices for approximately 66 minutes. When the NAS goes into sleep mode (i.e. not used for an hour), power requirements will be minimal and the UPS support period will be even longer.It has a nice display on the front which shows you various information including power input voltage/frequency, output voltage, current draw, battery charge level, expected battery runtime, and more. You swap through the screens by each press of the "Display" button. The screen auto-powers off after a few seconds if not touched. There is also a Mute button which can be used to switch off the very audible warning beep when there's a power cut.Overall, brilliant item that will hopefully protect my hardware for years to come.

Happy with this item

Attaccato alla corrente di rete l' uscita funzionava regolarmente, ma appena si distaccava dall rete compariva una scritta " E21" e l' uscita non dava più alcun alimentazione, questo anche dopo aver ricaricato a fondo la batteria. Restituito ed in attesa di rimborso, rimborso che a tutt' oggi (2 aprile 2024) non ho ancora ricevuto

Passt Perfekt zu einer DS 720.Hab mein komplette Netzwerk mittlerweile über die USV laufen mit Fritzbox, POE Switch, Klingel und 5 Kameras, hält ca. 35 Minuten.Perfekt.
