CyberPower CP850PFCLCD PFC Sinewave UPS Battery Backup and Surge Protector, 850VA/510W, 10 Outlets, AVR, Mini-Tower, UL Certified

I've been in IT for several decades and I can attest to the protections of having a UPS with voltage regulation as an extremely important feature to have. This one also has the sine-wave as well. As it turns out, my whole home generator happens to work with UPS devices that have the sine-wave functionality so I'm extra happy for that. I recently had some power outages and it operated perfectly. There's those few seconds of fluctuation before the home generator kicks in and our equipment connected to this UPS never missed a beat. I use this one for our main incoming coax cable for our Internet service and then I used a good short coax cable to come out of the UPS to go directly into my cable modem. So with that, all my other devices are plugged into the battery backup of the UPS. That includes my router, an extra network switch, my home phone ATA adapter, a NAS w/5 drives, and a hard drive docking station used for backups. Recently, I had an issue with one of my UPS units (I have two of these) and yes, their support took care of sending me a front panel replacement at no charge. They guided me with how to replace it and it worked fine. The unit itself never failed; it was the light indicators that weren't bright anymore, until after replacement. I had a large TV that was starting to show some purple scrolling lines every now and then so, after I added my 2nd UPS, it went away and never had the issue after that. Love this brand as it's more affordable and has some very good technologies applied. So, I have one that's about 2 years old and this one as my 2nd one. I've been very happy with its protections afforded me. Hope this helps others.

Does exactly what it's designed to do, the upright horizontalness of it's design allows me to have it in a location where it saves on space. And yes, it is effectively a backup battery system as well so if your power goes out, you can shut down your computer instead of it just losing power. This is really nice to have for a computer because as technology improves the CPU becomes more and more "capable." With that capability, it gets hot. This means it needs to stay cool. A UPS like this giving you the ability to tell your computer to shut down means that the computer can go through a process to cool the CPU for shutting down. And if i'm wrong on that you might want this type of product anyway because of it's space saving design and if your somehow ever in a position where you might pull more power than the power load of that breaker can handle (assuming it's set to a similar but lower limit) you have a chance to reassess your power usage without flipping a breaker. More specifically about this product, i've been making use of it for about over a year at this point and it's working exactly as it's intended to work. Does a click when it engages the battery power, a snap when it ends that process being back on shore power. And no annoying sounds.

While looking for a battery back-up for my Dell XPS 8300 desktop (Core i7) I read a lot of reviews and came to find out that certain HP and Dell desktops need sinewave UPS sources to function properly via battery back-up. Having used other CyberPower back-up sources previously (which have saved my PC's from burning up in power surges and electrical storms) and wanting to keep up with that solid record of performance, I chose CyberPower over APC. Out of the box this back-up is ready to go. Plug it in, and then your performance PC, monitor, modem, and router in the surge plus battery back-up outlets. With those plugged in the pull on the battery is still only about a quarter of the total accessible power (22% for me). The back-up unit's size is perfect for my small home office, and it will give me approximately 15 minutes to properly shut down my system during a power outage. It will also protect my phone and cable lines from power surges. I like the helpful digital dashboard software, and installed it after plugging in the power supply and hooking up my PC to it. It provides a nice way to check the status of the battery as well as setting up auto shutdown of the PC. The footprint of this UPS is compact, and the battery is replaceable. The fan can be heard, which for some (me included...) is new, but it's not terribly noticable. I think it's probably standard with sources over 400W. If you have a PC that's considered high performance and you are concerned about compatibility issues, check with CyberPower prior to purchasing this one to confirm compatibility.

This is my first UPC, and I've been using it for 13 months. I bought this instead of APC brand for several reasons: 1. Pure sine wave output (APC uses stepped approximation to a sine wave). 2. More outlets. 3. It cost less. 4. It looks very modern and hi-tech with its gloss black finish and sleek front panel sporting a great LCD display that provides lots of useful information. APC's design is more industrial and outdated - looks like it hasn't changed since the '80s. I bought this model based on the power rating, pure sine wave output and number of outlets, but as I've discovered I need even more outlets due to the poor spacing on the unit. The outlets are too close together and don't allow wall warts to fit next to another plug, therefore I've had to leave some outlets empty. In order to plug 4 cords into the 5 outlets on the battery backup side, I had to leave two outlets empty and use a triple outlet adapter to plug 2 cords into one outlet. The 5th outlet is partially covered by a wall wart and is unusable. Other than that I haven't had a single problem with it. I would order a larger unit with more outlets, but the spacing is the same. I called customer service to complain and suggest they make the units larger to allow more spacing, but was told they have no plans to change the design. Yeah, 'cause who cares what the consumer wants! I'd rather it was slightly larger with usable spacing - I prefer function over form. I knocked off a star for that reason. I received my unit at the end of January 2012, right in the middle of winter. There were several days where our power flickered or went out briefly, and I kept right on working on my laptop - my hub and external drives stayed connected as if nothing had happened and my cordless phone still worked. Of course my laptop would have continued to work for several hours even without a UPS, but I may have lost data when the external drives suddenly died, and I would have been unable to access those drives until power was restored. There was one day where the unit recorded 14 events, and I was sure glad to have my expensive MacBook Pro and 8 TB RAID drive protected! I have not used the coax or phone jacks, only the AC outlets. I did have to call the company to find out how to reset the events counter, because that hidden feature isn't covered in the manual. To reset the events counter, press the Display button several times until EVENT is shown in the LCD. Press and hold the Display and Control buttons at the same time for 3 seconds until you hear two beeps, then the counter will be reset to zero. It isn't necessary to reset the counter at all, but I find it interesting to check it once in a while - sometimes I find one or more events have occurred even when the weather was fine and I was unaware of any problems (I have the audible alerts turned off). It's comforting to see that it's been keeping my equipment safe from surges and under-voltage issues. Amazon's price was the best and included free shipping.

I'm impressed by this Cyberpower CP850PFCLCD. (NOTE: This is a review for the 2012 850VA model; no tilt/color screen and no USB ports.) I've only had it a week, and I only did one pull-the-plug test, but so far so good. UPDATE 1: Around a week after setting this up, I experienced a neighborhood power-outage and this UPS worked perfectly (maintained power and allowed me to manually shut-down). I've also had it the Mac Mini do auto-shut-down in later tests. UPDATE 2: After 9 years (now in 2021) the battery finally died. 9 years is Impressive! The OEM battery ("B.B. Battery HR1234W") and this UPS was active 24/7/365, through hundreds of power blips, sags, and outages, powering a Mac Mini, TV, soundbar, and a few other low-power devices. No problems. But I was surprised that this UPS did not give me any pre-warning about the dead battery. It just gave one last sad long beep (while muted), and stopped working... It wouldn't reliably power up, nor power devices at all. So I got a replacement battery (Power-Sonic PS-1290, 9 Ah), here on Amazon for about twenty bucks, and this UPS is happy and back to normal. PROS: Nice look/feel to the case, auto-off LCD screen, very informative LCD stats, no blue LEDs (yay!), semi-kid-proof power switch, and reportedly "green" power efficiency. My favorite feature is that I can keep it MUTED and it STAYS MUTED. I do NOT want to be woken up in the middle of the night. Happily, when muted, it has never beeped during power interruptions. It's completely quiet when on line AC power, and only has a quiet hum when providing battery power (about as loud as an old external harddrive). I like that it connects to my Mac Mini with no software install needed (Mac OS 10.5 in 2012 instantly adds a "UPS" tab to the MacOS power management panel, and adds a menu-bar battery-status icon so it's now has a battery like a laptop computer). Finally, my mind is at ease knowing this UPS has good AC sine-wave output (better than many other UPSs), according to the cool oscilloscope people. CONS: Minor issues: Sometimes the computer data connection doesn't always refresh after a power outage (I have to unplug/replug the USB cable). As others mentioned, the watts measurement is in fixed (~20W) increments, so this is not as accurate as a Kill-A-Watt meter. Finally, I hate that this and most UPSs don't cover damage if you're using extension cords for power input or output. WTFault?! My UPS-powered devices' approx stats with all things running: 100W -- LCD TV 20W -- Mac Mini (old 2006 model) 20W -- External USB harddrives, Ethernet switch, and a few other devices ------------------------ 140W -- TOTAL (sustained, non-peak load) = UPS reports 20 minutes run-time and 25% Watt-load (CP850PFCLCD model). Example loads and runtimes (approx.): 260W -- total PEAK start-up load = Reports 10 minutes run-time (but peak load lasts less than a minute). 140W -- total sustained load = Reports 20 minutes run-time (roughly 25% load on UPS). <10W -- total standby/sleep load = Reports 96 minutes runtime. :-)

Update 2 (11/2/17): I have reinstalled my original two APC BE350G UPS's. I found it interesting that one of them stayed on main AC power, while the other unit would constantly switch back and forth until the battery was depleted. After some more research, I learned that the APC units also have sensitivity adjustments (H/M/L) that can be changed via their free PC software (PowerChute PE) via USB cable. I connected both units to a PC and found that the unit that was not switching to battery was set to medium, where the one that was toggling back and forth, was set to high. I changed both to low, and now, both provide generator AC to the connected devices 100% of the time!! None of the network, IP cameras, or computers seem to care. APC even calls the lowest setting "generator mode". -------- Update 1 (11/1/17): After attempting a return via AZ's page, I learn that these are non-returnable. Fortunately, having received them only two days ago, and one still sealed in the shipping box, AZ's customer service very generously helped me resolve the return. Once again Amazon proves they are in the customer's corner. Think what you may of Bayzohs (yes, I know that's not the correct spelling, but I'm trying to get past the censors) and his politics, but dang does his company know how to treat us good. -------- I hate to be unjustly harsh, but, given my application and experience, I am beyond disappointed and frustrated. My setup: I have a diesel-powered (Yanmar engine) 14kW diesel standby generator, and a 200 amp auto transfer switch that provide backup power if utility service fails. While the main panel has 200 amp service, I have yet to exceed more than 10kW load at any given moment. Everything in the house works when on generator power; all electronics (network gear, PCs, 30+ IP cameras, TVs, etc), well pump, electric water heater, 4 mini-split AC units. Absolutely no issues powering anything/everything without a single hiccup. Unfortunately despite rock solid voltage, and frequency that stays between 59.8 and 60.5Hz, the APC battery backup units I have have conniption fits - toggling rapidly between batter any utility power (maybe once every 2 seconds) until the batteries are depleted - at which point everything connected gets connected and disconnected at the same rate. Horrible for electronics. So, I scoured Amazon for battery backups that tolerate generator power. This one, despite some reports of similar incompatibilities, seemed to have a number of people who said they had no issue with generator power. Thus, I bought two. When connected to the generator output without any load on the UPS, it stays on main power. However, after adding a few network switches and IP cameras, it begins toggling - just like the APC UPS's. I dropped the sensitivity to the lowest, and it made zero difference. This is with the generator having zero load change. I've tried it with minimal total load (<10A), and with heavier static loads. No difference. I was really hoping between the pure sine wave and power factor correcting technology that this would be the magic bullet, but even with higher feature set and higher price point, this performed no better than the $50 APC UPS's these were supposed to replace. I am contacting seller to initiate a return on both.

from - NW Dallas County Texas I have been buying these for at least 2 decades. They all still work like new. Every few years I need to replace the battery. I use them mostly because in the Summer time my home experiences surges and brownouts sometimes many times an hour. Most of my voltage issues are because the homes in my area were built in the early 1960's. The homes were not equipped with HVAC now most homes have it and many homes use at least 3 tons of AC and some like myself are running nearly 7 tons. Some homes have an older AC unit that may pull more amps then it was designed. That issue can effect the voltage at my home. I also use a backup low cost high output 220 volt whole house generator. This device protects my electronics from the generator very well. Never a bit of trouble. Absolutely will continue to buy this product over and over again well worth the money.

After having a good experience with another model of Cyberpower UPS, I chose this unit to replace an aging APC unit that would not work with my newest home computer. (Active PFC Power supply issue caused shutdown when on battery power) I have a 2011 Mac Mini and 24" Apple Cinema Display, and a pair of external HDDs plugged into the unit and even when the display is charging a laptop and the Mini is playing 1080p video it barely pulls over 100w! I know this neat fact b/c of the handy informational screen on the UPS which means I never have to unplug my computer to use a Kill-A-Watt meter again since the same data is available on the Cyberpower. I chose the Cyberpower 850PFC based on the sizing of the APC unit it was replacing and I have to say it may actually be over-sized for this newer and apparently very efficient system. I would have never realized this without the informational display and am now actually looking for a smaller UPS for this particular computer and will likely move the unit to my modem, switch, and router so I can use it's extra reserves to keep the internet alive longer during outages. As for the unit's interaction with the computer via USB, the Lion OS(10.7) sees the 850PFC and is very cleanly integrated with the UPS as far as controlling a graceful shutdown based on any of several available factors. All in all I believe this UPS is a fantastic bargain given the feature set and price.

We have the CP850 backing up a laptop and a 24" iMac. Easily runs 2hrs of light use during a power failure.

Aunque no es el modelo de las fotos sino el modelo anterior, que no tiene pantalla a color de posiciones, es una excelente UPS. el que sea de onda senoidal completa y no simulada es un extra. Donde la uso sufro muchas variaciones de voltaje y apagones de 10-20 segundos, mas cuando hace mal tiempo, esta UPS ha ayudado a evitar la perdida de datos. Tengo conectada una PC, una laptop y el alumbrado del cuarto. El cable USB permite conectarla y en automatico detecta como si tuvieras bateria de laptop en tu PC, aunque lo ideal es instalar el software, permite ver el consumo de energia, el tiempo de autonomia, calcular costos en KWh, ajustar la sensibilidad y a que voltajes bajo/alto intervenir, puedes configurar dias y horarios de auto-encendido y apagado, puedes monitorear desde tu telefono. la bateria es de 8.5ah pero tambien le queda la de 9ah del modelo siguiente que es identica en tamaño y agrega un par de minutos de autonomia.

Cuando renové mi anterior pantalla SMART TV LG de 43 pulgadas por un nuevo modelo Samsung de 65 pulgadas por motivo de liquidación del trabajo, pues me di la oportunidad de cambiar mi antigua por una mejor debido a que deseaba tener un mejor acceso a los puertos HDMI pues uso una PC de escritorio de alto rendimiento por el cual utilizo la pantalla como segundo monitor cuando deseo jugar estando en la cama. Como el modelo de Samsung que escogí como reemplazo tiene bocinas integradas de baja potencia, el cual se queda a deber cada vez que escucho el contenido que estoy disfrutando cuando hay presencia de lluvias fuertes ya que el cuarto es de techo de lamina, y ante la renovación del cuarto de abajo donde antes dormía, me tuve que traer a mi nueva habitación una barra de sonido LG de 2.1 canales con su correspondiente Subwoofer, y el reproductor Blu-Ray Panasonic, ya que mi hermano usa los servicios de suscripción en la pantalla del cuarto de abajo desechando el aparato al ver el contenido audiovisual a través de dichos servicios, además de que debo usar un switch de cinco puertos Ethernet para repartir la red de la casa entre mis dispositivos del cuarto en donde me voy a quedar, la nueva SMART TV, el Blu-Ray, mi PC de escritorio y un router inalámbrico al que uso como repetidor WiFi. Cuando compré su modelo hermano con mayor capacidad de watts, el CyberPower CP1500PFCLCD al tenerlo como referencia hace dos meses desde su compra e instalación, aunque su precio es alto con respecto al tipo de dispositivos electrónicos a salvaguardar de problemas de corriente al que ira destinado su uso en contraste con el modelo superior, al haber varias opciones a precios más económicos, pues tomando en consideración el costo de la SMART TV Samsung, pues me decidí por este modelo, y al igual que el modelo de 1350 watts, no decepciona ante los cortes de corriente que se han presentado en los meses que han transcurrido tras su instalación. Lo que no trae es alguna conexión USB en su panel frontal, pero la pantalla LED que monitorea el aparato, no se queda encendido innecesariamente. Lo recomiendo encarecidamente a pesar del precio, si se tiene pantallas SMART TVs de alta gama y/o consolas de nueva generación Xbox Series X/S y PS5.

This is an excellent UPS (Universal Power Supply). It is much smaller than the box that it comes in, and takes up very little space given that it provides ten outlets. It also has a neat display screen that allows you to see the voltage input and output, and even will allow you to see how many watts are being utilized by the devices plugged into it. The best part is that it provides surge protection and even with a full load it will allow anything plugged into it to stay on for an additional ten minutes (this is great for keeping a computer on until it can be powered down safely to protect data) during a power outage. Overall, this is a great product and essential for anyone who wants to protect their television/audio system and/or computer from unwanted outages that can cause data loss or destruction.

This is sine wave UPS, not a square wave to look like a sine wave. Read through the installation instructions and then the programming. Very easy to install and fairly easy to program. Put it in silent mode. Using it for our Modem / Router and if needed our cell phones. A week later, there was a power outage in multiple neighbourhoods. The UPS worked perfectly and recharged fairly quickly. Quite happy with this product.
