CyberPower Intelligent LCD CP1000AVRLCD 1000VA Tower UPS (CP1000AVRLCD)

Though I've only had it for 2 weeks, our power has already been off. The CyberPower unit kicked in and allowed me to finish my task & power down the computer,…

Pros: I have several Triplites with the same rating, but they didn't have as slick of an interface, plus I like being able to check the power usage from the…

This unit installed easily and out of the box. You do not need to let it fully charged before using it. I read that in some reviews that you have to but you do not.…

Installed in public library. No problems during 3 power incidents since Nov2010 install. Unit runs quiet and does not heat up under the desk.

Pros: Nice size, decent runtime, decent wattage, decent softwareCons: Wish it had plugs spaced out more, but I'm sure it would increase the size.Nice size, decent runtime, decent wattage, decent software Wish it had plugs spaced out more, but I'm sure it would increase the size. Power went out once, it shutdown my PC as instructed.

I haven't had a power outage since installing but tested this unit by unplugging. Found the UPS to kick in power and last longer than I expected. This replaces…

Pros: Flashy, Small, Adequate amount of outlets and coverage.Cons: Outlet spacing sometimes makes it impossible to use some peripherals.Flashy, Small, Adequate amount of outlets and coverage. Outlet spacing sometimes makes it impossible to use some peripherals. Owned this unit for appx. 4 months. Turned on the PC, started cruising the internet, and the unit shorted itself out. Tripped breakers and alternative surge protectors in the house. I double checked the unit by plugging it back in and sparks flew from the top. Oh my, If I hadn't been home, it could have set the house on fire. I probably wouldn't take the chance on this unit again, it's made in China, how much can you trust products from there anyway.

It works better then it was listed to work. It seems to last linger during a power outage then I thought. I had a computer run during a whole blackout that was…

compact, powerful, and easy to use. No problems so far after 3 weeks

It ran great for 3 years and two weeks.

Great Price.

Pros: Works great, I love the LCD display. It handles our dirty utility power with no complaint or fault.Cons: Does not appear to be supported by FreeNAS 0.7.1 / FreeBSD, neither with serial nor USB cable. I didn't expect it to be; I purchased this UPS based on performance and price.Works great, I love the LCD display. It handles our dirty utility power with no complaint or fault.

Configured this on a Windows-based computer (with included software), turned off alarm sounds, set for max run time then hooked up my FreeNAS server. Works fine for my needs.

Pros: Delivers clean power to large PC (800watts), Printer, 24" monitor, and other misc items without issues. Still providing a 16 min runtime for battery back up.Cons: noneDelivers clean power to large PC (800watts), Printer, 24" monitor, and other misc items without issues.

Pros: Works great. Easily sets on/off when attached all attached hardware is going to be OFF. Love the LCD readout. Small footprint. Use with I7/920 12gig and viewsonic 22".
Will replace APC900 for old P4 server next. Soon.Cons: Had problems with on/off schedule of software. Power button is great for that, tho. Comes on in about 10 seconds.

Who really needs a schedule for on/off anyway? Some users say they have a laser printer in their units - I understand that's a no-no for any UPS because they draw so much power, besides who needs to print during a power outage?

Awesome UPS. No complaints, love the digital readout.

This backs up my TV, Roku and broadband switch. I also have one on my computer. I like the AVR feature , with surge protection. Think about what you spend on…

Pros: Obvious on/off switch, voltage/frequency/wattage monitor, line conditioner, runtime estimate, audible trio of beeps when battery mode kicks inCons: heavy (as all batteries are), bright blue on/off switch is a lure for children, uncertain Linux compatibility (-1 egg)Obvious on/off switch, voltage/frequency/wattage monitor, line conditioner, runtime estimate, audible trio of beeps when battery mode kicks in heavy (as all batteries are), bright blue on/off switch is a lure for children, uncertain Linux compatibility (-1 egg) This has saved my system several times, as I live "in the sticks" where surges/outages are common. I keep it on the desk, next to my monitor to keep it out of reach of my son. I keep a modern 'budget' desktop, an old server, a LCD monitor, and a CRT monitor on this. It's fantastic.

Bought this UPS to keep my modem and wireless router going in case of power failure. Tested it, and it kept it all running smoothly for 3 hours. Would recomment it.

Pros: Simple setup, Light Software footprint, Functional LCD Display, Great Value, Nice form factor, Windows 7 comparabilityCons: No dedicated wall wart jacks. Power LED is a bit bright but not as bad as some of the chargers I have in my room.Simple setup, Light Software footprint, Functional LCD Display, Great Value, Nice form factor, Windows 7 comparability No dedicated wall wart jacks. Power LED is a bit bright but not as bad as some of the chargers I have in my room. I got this to replace an old UPS that had gotten to the point where it would just cut power on fluctuation in voltage. This unit works perfectly for the poor electrical in my town. So far it has never tripped into battery mode despite the lights flickering in the wind. Unlike the competitors software which is a resource hog. This software is no frills, just allowing you to view parameters and select how you want it to deal with hibernation. Plug and play was brilliant on windows 7. And I really love the LCD screen. It's fun to watch the input V drop to 118 and the output stay at 120.

Pros: Front LCD display, # outlets ...Cons: none Kept my system running a few times when power went out; works as advertised.

I purchased this unit because my APC unit failed after three years. It seemed like a battery problem, but putting new batteries in the unit did not solve the problem. This was my third APC failure in the past few years (three failures out of five units purchased). So I decided to try a CyberPower unit. Time will tell how it holds up over the longer term, but at this point, I really like the unit. I have two computers, a laptop, router, switch, modem, and phone hooked to the unit and it handles the load with ease. I love the display as well. This display is similar to the APC display in that by pushing a button, you can show output voltage, input voltage, output frequency, current load in kilowatts (why not watts?), and estimated run time with current load, percent battery charge, and percent load. It has an indicator bar for the battery charge and current load. It also sports various indicators for different parameters. It has a large blue indicator which is also the power on/off button, and provides AVR or automatic voltage regulation for an input range of 90 to 140V. Remember that watts and VA are two different things. This 1KVA unit will provide for 600W of load not 1KW. The unit has five battery/surge protected outlets and four surge only outlets. This is more the adequate for my needs and I would think most people s needs. Overall, I really like this unit. Will the long term reliability beat the APC units? Time will tell.

Has no options for voltage transfer settings. Is extremely sensitive to frequency fluctuations -- constantly switching back and forth while on (an electronically regulated) generator (fluctuations of only a few tenths of a Hz).

I ordered this AVR UPS but didn't pay as careful attention to the plug configuration as I should have. You cannot plug in anything slightly oversize which makes it useless for me as I need all the plugs on it. They are also at a 90 degree angle which makes some plugs (oversized rectangular that normally would still work, not work. Probably a good product...it at least keeps the door propped open well.

This should be considered MANDATORY if you have any big money invested in your home theater. Not only protects against spikes, it also covers brownouts which are much worse for modern electronics (the AVR suffix in the model number). A small price to pay for peace of mind; get it when it s on sale with free shipping

Pros: Led display easy to read. Nice that the display shuts off.Cons: Power button lights up with a bright blue led. annoying when in the bedroom.Led display easy to read. Nice that the display shuts off. Power button lights up with a bright blue led. annoying when in the bedroom.

The only downfall for me using this as a server is that I need more robust software to monitor on my network, but other than that it's a 5 star for me.

I have owned various UPS units which have all filed. I just purchased 2 of these units which are great. Nice features and it is simple to set up. The interface…

Pros: When working it served its purpose, software was simple and straightforward to operate.Cons: I've owned this about a month. Today the alarm went off on it and my setup powered down, as soon as the unit kicked over to its battery sparks and a small flame came out from the unit. Luckily I was at the computer when it happened and was able to quickly unplug and remove the unit from my apartment. I'm currently in a RMA process for a replacement but I'm not certain I want this unit again for fear of a similar issue.When working it served its purpose, software was simple and straightforward to operate.

If there is a power failure, and you shut it off, you cannot turn it back on to run off battery again. I bought this unit primarily to run my Vonage during a power outage so as to have access to the home phone. Secondarily as a surge protector for two of my home computers. During the last power outage it ran a cable modem, Vonage router and cordless phone base for 10 hours while hardly running the battery down.

The unit worked perfectly and after the power did not come on after 5 minutes, the included software shut down my computer. I'm satisfied!

The tests I made show good I am getting about 2 hours time as all I have are a 100 watt Pentium 3 homemade Linux server and my network router and modem . I have…

Pros: looks goodCons: Battery life is severely diminished with anything more than 1 PC and 1 monitor. Life remaining on LED display in NEVER accurate when a power failure occurslooks good Battery life is severely diminished with anything more than 1 PC and 1 monitor. Life remaining on LED display in NEVER accurate when a power failure occurs If it gives slots to be plugged into, it should be able to allow at least 3 minutes to power down those items plugged in. I am lucky if i get 1 1/2 minutes. On top of that, My PC has had the blue screen of death 2 times requiring tech support to resolve fatal problems. Each time i was not able to power PC down in time during a storm. Whether the surge protection is working is anyone guess. I have other computers not even connected to this that have never had a problem during storms and power outages.

Ordered the UPS on July 26, regular shipping, and the order arrived the next day. Easy to install and have had no problems with it.

For Performance, Quality, & Price the best I have ever owned.

Pros: Excellent product, using in Afghanistan on dirty generator power. the AVR feature makes sure that no more than 115v gets to our ASUS Home server, and 3 personal laptops. Even pushing all those and two wireless routers battery backup time is about 55 minutes.Cons: None...Excellent product, using in Afghanistan on dirty generator power. the AVR feature makes sure that no more than 115v gets to our ASUS Home server, and 3 personal laptops.

This product hasn't been tested so far by a power outage. So, I really can't say how it works in regard to that situation. Hopefully, it will do well.

Pros: substantial wattage rating, compact design, LCD front panel indicator and Automatic Voltage Regulation. Lots of features packed into a small form-factor UPS. I Love having the ability to see how much of a load my PC is drawing. Nice GUI interface to monitor status.Cons: Not really a con but would have liked to be able to choose whether to have the front panel on at all times. Also, the large, blue on/off button is somewhat easily turned off. So be careful where you place this UPS if you have small children or pets. I have accidentally shut mine down a few times before I placed a small piece of plastic, acting as a cover, over it to prevent accidental outages. I would also like to see a selection of adjustments in the sensitivity menu instead of one, set level.substantial wattage rating, compact design, LCD front panel indicator and Automatic Voltage Regulation.

This second one is protecting my i7 gaming and benching rig. I live in an area that sees frequent power fluctuations and outages during storms. So far the CyberPower UPS has done it's job. Good price for value and a nice warranty. It has enough wattage to allow my expensive, power-hungry i7 (240w at idle) to shutdown during a power outage.

I just got this and not even a day, it already paid it self off 4 times. Def. recommend this product.

Pros: Fantastic product, features are great. gives you a good prospective on what kind of power you have flowing through your house (consistency wise).Cons: None hereFantastic product, features are great. gives you a good prospective on what kind of power you have flowing through your house (consistency wise). None here Wish I could have gotten more for less $$ but isn't that always the case?

Our company has purchased about 20 of these, and about 8 of the 1350VA models. They are some of the best USP units we have ever had. they are cheaper then the APC UPS units and the built-in display has a ton of info. I would reccomend this company to anyone.

Pros: Easy to setup. Easy to understand. I like the LCD feature and knowing the power consumption of my components. Relatively small compared to past UPS units and not nearly as heavy (~25lbs)Cons: The box looked like it was drop-kicked a couple of times. No damage to the unit though.Easy to setup.

I bought 2 of these power back ups and it saved my equip. within the first week! Long story short, wind blew dirt in my breaker box causing a short, this item was able to alert me, show the exact power input fuctuations and protect my equipment until electrician could fix the problem.

Fantastic product.

Large backup power
Energy efficient Does not continuously filter power for 120 Vac, will only filter when power is outside of normal parameters. I bought the CP1000AVRLCD as a UPS to filter out any anamolies in the power supply but I learned from the owners manual that the unit does not continuously filter the incoming power and only sends power through the transformer during a problem. However, this will help in terms of energy efficiency. I'm sure it can switch over fast enough that my PC's power supply won't notice the hiccup.
The LCD screen is pretty handy. Even tells you how many watts your devices are drawing at any time.

It did a good job protecting my computer. I love the display on the front panel. It's handy and informative. This is a good UPS. I like and would recomend it.

Pros: I just need something that covers the odd power glitch, or maybe a few seconds where the power drops sharply (the wiring in our home was apparently done by the Amish). I've used a CyberPower UPS on both our home PC's for years and have never had the slightest problem with it. When I built the latest computers we own, I knew the previous UPS's couldn't possibly support it, so I reached again for CyberPower. If this unit lasts like the previous two I've been using, I can safely run this for at least the next 5 years, easy.Cons: The power button seems to 'float' in the socket. It's not really a con, but it doesn't always settle to a 'straight' position if it's been used.I just need something that covers the odd power glitch, or maybe a few seconds where the power drops sharply (the wiring in our home was apparently done by the Amish).

I was surprised how small this is, it's barely larger than the previous UPS I'd had connected, and is much more powerful. The LED frontscreen is nice-would have been nicer if it could be software-activated, too.

Pros: Set up easily. No software needed with Win 7 RC or Vista so i did not try to install it but have used the same power software before and it was great.Cons: None as of yet.Set up easily. No software needed with Win 7 RC or Vista so i did not try to install it but have used the same power software before and it was great. None as of yet. On my just built low power (100 watts with 22" monitor) the battery went on and on right out of the box. I plugged it back in after 1/2 hour. We'll see how long it lasts. Replacement battery info on Cyberpower site. Good.

Pros: Informative screen
Voltage conditioning
Programmable through computerCons: The manual and box claim outrageous battery life. I don't know why. 35 minutes? I think not.Informative screen
Voltage conditioning
Programmable through computer The manual and box claim outrageous battery life. I don't know why. 35 minutes? I think not. I bought this unit because sometimes the power will flicker on and off for whatever reason and I became tired of getting interrupted while using my computer. Using a 24" LCD monitor, the predicted battery life is around 17 minutes. My computer is performance-oriented--or it was back in 2005.
It clicks seamlessly between battery and outlet. A great purchase.

I much happier with my new CyberPower UPS than my old APC system. I love the LCD display and all of its readouts. I also love that it connects to my Mac and gives me readouts in my menu bar. I was always clueless as to what the status of my APC system was or how much longer the battery power would last. Now I know exactly either on my screen or the screen of the UPS.

The best battery backup unit is one that does the job without you knowing it's there - until the power goes out. This one can handle our TV, surround sound, TIVO, and…

Pros: Quiet, small footprint, achieves manufacturer's claimed battery run times, LCD screen, good valueCons: "Silent mode" not always silent, backlit power button too bright, lower power rated APC units provide more battery backup timeQuiet, small footprint, achieves manufacturer's claimed battery run times, LCD screen, good value "Silent mode" not always silent, backlit power button too bright, lower power rated APC units provide more battery backup time I purchased this to replace an APC BR800BLK that makes a constant annoying buzzing (not just when running on batt). This was my second APC to disappoint, the other being a home theater unit that I took a loss on restocking fee at the store I bought it from to trade for a Belkin unit that has been trouble free. I first considered Belkin for this UPS purchase but their website shows all models discontinued, I assumed they've left the computer UPS market. My research led my to the CyberPower and besides some minor complaints it's a great unit. Setting the software for "silent mode" only keeps the UPS quiet until it registers 5 mins of battery time left then it beeps constantly. Could wake you up if your computer is near or in your bedroom during a power failure. Unit should stay silent completely like APCs do. I had to put a piece of black electrical tape over the power button because the glare of the too bright light is annoying. My 800VA/540W APC unit gave me 25 mins of batt time vs 17m

This is really easy and simple in opration. The display is programmed nicely to provide all important data to user. I have not used the software come with this product. Bottomline great product at this price and free shipping.

HAVE NOT USED SOFTWARE YET. PRODUCT IS DOING JUST WHAT I WANTED IT TO DO.I JUST NEEDED SOMETHING TO CLEAN UP MY POWER BEFORE IT GETS TO MY COMPUTER.
IT LOOKS GREAT AND I LIKE THE BELLS AND WHISTLES.

About 6 months ago i bought my first cyberpower UPS system. This is my second and its better yet and i am running them both at the same time and i have over an hour of battery time with 6 moniters, CPU, all in one printer, speeker system, DSL modem, Router, Laptop, phone, and lamp. I also have a cyberpower adaptor for my laptop to use in my car. it also works great

I replaced two APC UPS units, one of which (an 18-month-old Back-UPS ES 750) was intermittently insisting that there was no AC. Based on the reviews here and elsewhere, I bought two of these CyberPower units (and recommended it to a relative for a small office environment) and two months later, I couldn t be happier. The software is easy to use and the product has supplied clean power for months through power interruptions / outages. Based on the reviews I ve read, I expect these units to last a long time!

While relatively expensive, it cost less than replacement batteries on my old UPS. What can I say other than it works.
