CyberPower CP1500AVRLCD Intelligent LCD UPS System, DISCONTINUED * SEE NEW UPDATED MODEL CP1500AVRLCD3 *

Bought this almost 3 years ago and works perfectly fine until one day the UPS started to randomly mute/unmute itself frequently which causes it to create a beep-beep sound when muting and a beep sound when unmuting. I figured it is the front LCD circuit board that had an issue. Since I was still under warranty I contacted Cyberpower and they were able to send me a replacement front panel to replace it. Now the issue is resolved

Very satisfied, thanks allot.

ONE: After much researching... you can't plug one UPS into another UPS to extend power. You can damage both.You can get two, one for the PC, one for the monitor.TWO: The newer UPS models check your 120V wiring. If this unit finds a wiring fault (little light on the back) the UPS WILL NOT BE RECOGNIZED by your PC. Nothing much about this is stated on their web site nor manual ! ! Trying to install the software will shut your PC down as the software shuts down if it can't find the UPS. Yes, for a few seconds there is a cancel screen !So I buy this unit for my Vista Business 32bit PC. It says it's Vista 64bit and Win7 compliant, not many are and everyone is moving to the faster 64 bit Win 7. I would first download the newer PowerPanel version.As stated above this and other newer UPS models, will check and NOT WORK with bad wiring (reverse hot, no ground). So if you are getting a newer model UPS get a wall mount outlet checker for $4 at your local discount store. They plug into whatever wall outlet/extension cord you are going to use for the UPS. They have three lights, two amber and red. If just the two amber light up... no problem. I had a bad extension cord and the UPS started but would not be recognized after loading the software, then it would shut down the PC. I found the "fault light" on the back and switched the extension cord. That fixed the fault light but the UPS would still not be recognized. Reinstall, upgrade to the newer version PowerPanel, nothing would keep the software from shutting down the PC except the "cancel" on the shutdown reminder.I find, by accident, that if the UPS finds a "fault" the UPS will stay in "fault" until the UPS is shutdown. I just changed my bad ext. cord and never turned it off the PC1500. Once everything was turned off and restarted the driver was loaded, UPS found and I wrote to the company to suggest they put this on their FAQ.First: Check the "fault wiring" light. Second: if it went into fault, you must shut down the UPS and fix the problem.Doesn't everyone have their PC right next to a wall outlet ! ! If you are going to try this with a two wire ext. cord , or broke off the ground tip to fit it in your two wire wall outlet(no ground), or you filed the cord end to make it fit the plug (reverse ground), this unit will power up.. just not be recognized by the software. Even the web site is not accurate for all models as the "fault light" on this model will either be on (bad) or off. The web site says it should blink on/off, but not with this model. Wouldn't that O.K. blinking light waste power? Oh, and by the way, the nice demo image shows a "blue LCD screen". That only stays on for 15 seconds or so. It goes off as an energy saver (.0001 watt ?) and to "save the LCD from burnout". So to see what's on the UPS LCD, you must press the button below the LCD. It does have 5 different screens with lots of tech info about the outlet power and stuff. Gee, everyone puts a UPS were you can easily reach it. None of these LCD items are on the PowerPanel pop-up screen. So buy a short stick too !UPDATE 2012 - Hurricane SandyFor whatever reason, when this was plugged in to my PC and the power went off due to the storm, it fried my power supply ! When the power went out then came back on for 3 seconds I heard a pop and sizzle. I then smelled burnt plastic. I did not know were it came from. A week later (thanks JCPL), when power was restored I turned on the UPS, then the PC.. pop and sizzle my power supply went. This was plugged into the UPS battery part... maybe the power supply was going.. I swapped out the PS that day power was restored and everything worked. I was able to get a replacement power supply via that companies warranty. The UPS has not blinked those next 5 months.... ? ? ?

I work as a network technician and have used APC equipment for many years. Their high-end units have always done well for us. For many years, I also used their Smart-UPS brand for my home network needs. As they've become old and had problems, it became more economical to replace them, instead of fixing them, especially, since for my desktops, the industry was moving to USB for signaling, and away from serial ports. My rack still has older 1400 VA SU units using SNMP management cards, but I needed a new desktop solution.For the past three years, I stuck to APC's consumer products and have been very disappointed. They have more problems than the older units I've grown to love, and because they change models so often, it's harder to find a battery replacement. Plus, they just have a sort of cheapness about them.With my latest computer purchase, a dual quad Mac Pro, my older 800VA APC just couldn't handle it. So, I decided to try this Cyberpower 1500 and have been very pleased with it, using it for about 2 months so far. The signaling and reported time is more reliable than the APC I was using. Although it should be said, any consumer UPS will not guarantee exact runtimes, load measurements, etc. - For what you are paying for this amount of capacity, some sacrifice must be realized. If you do your calculations correctly, and use it as needed (surges, brown-outs and limited black-outs), these units will fulfill your needs. If you need super accurate measurements and reliable AC power generation, then you should consider a high end unit, such as what APC offers for data centers.The load reading for this unit, when measured with a Kill-A-Watt is pretty accurate. I like the soft blue lighting with auto-off. I connect my two, 24" LCDs to the APC 800VA unit, and the Cyberpower handles the Mac Pro with three, external FireWire drives with no problems. Testing it, by turning off the circuit breaker (shouldn't pull the cord from the wall), reports about 20 minutes of runtime, which seems about right. I've left it on battery power for about 10 minutes, and the readings remained fairly constant. I live out in the country at the end of our power grid, so I get a lot of "dirty" power. Brown-outs are common, and my larger UPS units have the ability to generate statistical logs each day of the power fluctuation. I feel pretty safe with this unit, and wouldn't hesitate to purchase another one.Lastly, the software both Cyberpower and APC provides for the Mac OS, is really bad! I prefer to just use the Mac's SysPrefs to configure the UPS settings and leave it at that. Both companies desperately need a re-write of their OS X software.
