I used to be incredibly brand loyal to a different manufacturer, but after a lot of recent letdowns, I decided to give Cyberpower a try. About 3 years in to my first unit and it hasn't let me down once. Cyberpower is now me brand of choice for power backup.

Almost 3 years old now and have had zero issues. mostly bought this because of the thunderstorms in Florida. It powers my owc 8 bay which is full of drives for about an hour and a half during the storms.

Got it to protect some home theater equipment. Does the job to allow time for a proper shutdown.

The pictures on the website show the newest model of this well regarded UPS. The tech specs listed 10 vs 12 recepticles and older info based on the previous model. The price was also the best I could find for this UPS, so I figured if it happened to be the older model, I would still be satisfied. Fortunately, they 12 plug new model arrived in a few days and has worked flawlessly in my home office setup. I have it supporting supporting my networking, modem, wifi, primary desktop, and a full sized Dell T610 tower server running a lab. During standard usage on all of that, I pull about half capacity on the UPS, and it show an aproximated runtime of 12-14 minutes. I'm not massively concerned with runtime after power outage, but I get brownouts and blips that this keeps from downing my systems. I plan testing it with just modem, router and wifi one evening to see what the runtime would be with most things down save for connectivity during storms, etc.

I would rate the UPS pretty darn good over all. Paired it with my gaming rig, Mac & a couple monitors and it's been handling it well. I tried simulating a power outage myself and it held up just fine enough. The display is really cool and shows me how much power the plugged in components are drawing in real time. One quirk about the display is that it does not show a power output value (shows 0 watts otherwise) if the devices plugged in do not draw more than 30 watts of power. I found that kinda weird, but otherwise for a active PFC UPS, this is doing the job real fine.

Love it so far. I?ve only been using it for about 2 weeks but my power did go out once and it held up just fine! Definitely recommend!

Such an awesome purchase. Definitely delegates and uses power appropriately. I live in an area with regular brown outs and power surges and with my pc plug into this, I have no problems

First received was damaged (as is common for the heavy internal batteries to knock loose and damage things but replacement is just fine. Reasonable run time and an external mute. I've had CyberPower products that have lasted 5-8 years with original components, whereas my APC batteries have died within 2 years. Here's hoping this one has the same longevity as the 3 other CyberPower battery backups I still have in use.

Unlike my old UPS which used a LOT of electricity by making lots of heat when power correction was needed this new model is not only cutting edge in voltage/current protection but it also is EXTREMELY energy efficient! {Probably a Zener diode or something similar} Also it does not "confuse" power supplies. When taking over in a failed service condition by matching the sine wave and just taking over seemlessly. when things are fine no battery is even used , even for small power corrections....thats NICE

Very easy to setup and use and provides great protection for a very reasonable price.

It's working fine right now as far as I know, and which is expected. Should be asked to rate this 3 years from now.

Awesome, sleek backup power for my new Dell All in one. My whole system, including router is powered and I have 2 hours of power according to the digital display. The thin design allows for a smaller space. Really like this Cyberpower model!

Superb features in a decent price range. Only time and power incidents will tell if it performs as advertised.

bought this for power outage for tv and xbox. has worked fine during outages. gives plenty of time to turn off everything during outages.

Bought for my DS1618+.Voltage instability is the main cause of hard drive damage

No more concerns about losing data whenever the electricity flickers on and off. Cyber Power works as advertised, and is a great price for the budget! I highly recommend this data-saver!

We have used our unit for many years. We lived an an area where trees falling on our power lines caused a number of power losses. It saved us each time.

Numerous power interruptions in my area. Decided to research a battery uninterrupted power supply. This unit met my criteria. Handles voltage and wattage well, excellent displays, and has performed exceedingly well during unexpected power interruptions.

The CyberPower Standby CP350SLG uninterruptible power supply (UPS) safeguards PCs with non-Active PFC power supplies and other electronics (monitors, cable DSL/ modems, VoIP routers, fax machines and home theater equipment) from blackouts, brownouts, surges, spikes, sags and other power abnormalities. Its composite integrated circuitry offers advanced lightning protection.
The CP350SLG unit has a capacity of 350VA/255Watts, six NEMA 5-15R receptacles, including two widely-spaced outlets to accommodate transformer-based plugs. Its compact design allows for horizontal or vertical placement. This UPS has a maintenance-free 12V/3.6Ah battery. Protection for phone/network (RJ11) is also included. EMI/RFI filters increase the immunity of the load to disturbances and surges.
