CyberPower CP850PFCLCD Line-Interactive UPS System

Offering battery backup protection for individual work areas, home networking, entertainment electronics and equipment requiring Active PFC power source compatibility.

Why You Need It: When power goes out for even a second it can result in data loss and hardware damage which can shorten equipment life expectancy. This battery backup unit provides sufficient emergency runtime power to allow for safe closure of open files and proper shut down of electronics when an outage occurs. In addition, it safeguards electronics from commonly occurring power surges caused by storms, activity on the power grid or high-powered equipment turning on and off. Automatic Voltage Regulation (AVR) stabilizes incoming voltage, preventing chronic problems caused by minor but frequent power fluctuations. Computers and other devices using high-efficiency Active Power Factor Correction (APFC) power supplies require pure sine wave AC power (as supplied by utilities) for trouble-free operation. This PFC Sinewave battery backup ensures equipment using APFC power supplies will not unexpectedly shutdown or experience harmful stress when switching from AC power to battery power.

Typical Use

Provides pure sine wave backup power and surge protection for individual work areas, home networking hardware and devices, entertainment electronics and equipment requiring Active PFC power source compatibility. Safeguards valuable documents, photos, videos and music files from loss or damage due to power fluctuations and surges as well as uncontrolled equipment shutdown caused by power interruptions.


Pure Sine Wave Output — Provides power protection to ENERGY STAR 5.0 devices with Active PFC power supplies and non-APFC power supplies.

Surge Protection — Prevents damage to equipment from surges and spikes, including lightning, and also safeguards telephone and fax equipment, cable modems and routers from power surges traveling through unprotected phone or data lines (RG6 / RJ11 / RJ45). The amount of energy a surge protector can absorb is measured in joules. A higher joule rating means more protection.

Ultra-Quiet Operation — Eliminates distracting fan noise normally emitted by battery backup units.

ENERGY STAR Qualified — Recognized by the US Environmental Protection Agency (EPA) as one of the most energy efficient battery backup units available.

Automatic Voltage Regulation (AVR) — Corrects minor power fluctuations, including under-voltages, without switching to the battery, thereby extending battery life - essential in areas where power fluctuations occur frequently.

Multifunction LCD Panel — Displays battery backup vitals for easy monitoring of run-time and power conditions.

Additional Features

Energy-Saving Technology — GreenPower UPS Bypass Design saves energy costs by reducing power consumption and heat buildup.

Computer Monitoring — PowerPanel Personal Edition management software allows for controlling and monitoring the battery backup to safeguard open files and connected equipment during an outage.

USB & Serial Communication Ports — Allows communication between the battery backup unit and the PowerPanel software installed on the connected computer to enable power management and auto shutdown functionality.

Noise Filtering — Advanced EMFI/RFI noise filtering coils reduce electromagnetic and radio frequency interference that cause disruptive humming and static.

Wide-Spaced Outlets — Large transformer block-style plugs can be connected without obstructing other outlets.

Building Wiring Fault Indicator — LED status light on battery backup unit indicates wall outlet wiring problems, such as improper grounding, that could inhibit surge protection or cause shocks. When lit, a professional electrician should be contacted to correct the problem.

Audible Alarms — Distinctive tones sound when the backup unit is on battery power, overloaded or low on power. The alarm can be silenced if desired.

Free PowerPanel Personal Edition Management Software

PowerPanel PE is included with this battery backup unit and is easily downloaded and installed on any computer. Its diagnostic screens facilitate complete control of the battery backup unit's capabilities.

5 out of 5 eggsSo far so good

Pros: I bought this to protect my Mac Mini setup. Lately we've been having power issues due to stormy weather, and my Mini was just too expensive to plug into a "surge protector."

This is a nice UPS, especially for the price. The display is informative and you can keep tabs on how much power you're drawing from the 'battery side' of the unit. I'm quite surprised that my monitor and mini are only drawing an average of 25 watts!

Cons: The only con is the packaging. This particular item was shipped via FedEx, and the "security tape" on the outer box had been cut and re-taped. Since the FedEx guy just left it on my porch, I had no opportunity to inspect it before accepting it. (I was home, just didn't hear him.)

So I opened the outer box and was pleased to find box around the unit was not tampered with. Something to keep an eye out for. If it was something very delicate like a MoBo, I would have called FedEx immediately and sent it back.

Other Thoughts: We haven't had any power issues since I received it yesterday, but when we do, I'll write another review depending on how it performs. Fortunately OS X recognizes the unit immediately when you pled in the USB cord, and you can set the computer up for a safe shutdown when the UPS switches to battery power for a set amount of time.

5 out of 5 eggsExcellent

Pros: This is the best UPS I've owned. It does everything it's supposed to do and without any irritating noises.

Cons: None

Other Thoughts: I live in Florida where power surges and lightning strikes happen regularly. After 1 year this unit has logged 132 events.
That's over a hundred times this thing has saved my hide!

I will be buying a 2nd one soon for another room.

5 out of 5 eggsBest UPS for the money

Pros: Advanced features and quality not available from other manufactures at this price. Great lifetime equipment warranty.

Cons: None.

Other Thoughts: For the reviewer that wanted his unit to work with more than one PC, download uninstall the PowerPanel Personal Edition of the software and install the FREE CyberPower PowerPanel Businesses Edition. Install the Agent on the PC connected via USB to the UPS, then install the client onto any other PCs connected to the same UPS. You can configure all the connected PCs to now shutdown together. The Business Edition also has much better logging and monitoring functions.

5 out of 5 eggsHi mom

Pros: This is a very nice unit for the price. I have a variable power supply in my computer and the Pure Sine was a must. I spent a day or two reading up on different brands, and noone could come close to this one in features or the price.

So far i am really happy with this purchase.

Cons: Unit only has one USB port. I was really hoping and should have checked before purchasing this unit, if it had the ability to shutdown more than one computer in the event of a power failure. I am a member of Turbo Nerd Inc, and have 2 computers at my feet that i was hoping to use this unit on.

Not CyberPower's fault i didn't look into that enough, no eggs docked for a feature i "wish" it had..

Other Thoughts: I enjoy reading reviews from others complaining about the "Beeping" it does in the event of power failure.

The manual tells you exactly how to turn that off.. They send that manual for a reason you know.

1 out of 5 eggspretty paperweight

Pros: looks nice

Cons: would not turn on fresh out of the box

Other Thoughts: Unpacked the box, plugged it in and charged overnight. Will not turn on. Opened battery compartment and checked connections. Tested battery, fully charged fine 13.3V. I have the feeling that this was never tested coming off the assembly line and that does not bode well for Cyberpower quality control.

5 out of 5 eggsGreat Power Supply

Pros: PFC compatible.
Pure sine wave.
LCD display.
Somewhat adjustable voltage sensitivity.

Cons: I wish I could adjust the voltage sensitivity to be tighter. Something along the lines of 110-130.

Other Thoughts: This is the best power supply on the market in this price range.

5 out of 5 eggsAWESOME!!!!

Pros: Works great. Connects to 8 devices. Lasted longer than my ACP one I bought a year ago.

Came fully charged and no need to wait for hours to charge before use.

Cons: None that I'm aware of. although it could have better spacing between some of the plug-ins for these abnormally large power packs and weird ones that plug in sideways.

I don't want to lose any plug-ins though, so you'll need to make it slightly bigger.

5 out of 5 eggsGreat UPS

Pros: Great UPS...

Bought it to keep a new computer with Active PFC running
during power outages.

My new computer uses Active PFC power supply and needs pure
sine power from UPS to keep it running correctly.

Before I got this unit, I had another brand UPS and when the power
went out, the power supply on the new computer produced a fast ticking
noise. It sounded bad.

When I put this UPS on the new computer, the power supply sounds
normal even when the power goes out.

Cons: no auto off outlets after main load is shutdown.
