Excerpt: We have been purchasing this UPS for over a year now to ensure our HP DC7900 Small form factor PCs operate correctly due to their PFC power supplies. This UPS excels at that. With over 20 units in production, only one failed and that one was DOA.
Excerpt: This unit produces a true sine wave which is required for active PFC used in newer computers. Don't damage a new computer by using a cheaper UPS that is only designed for passive PFC power supplies....also has a voltage regulator built-in...
Excerpt: Living in Texas, thunderstorms are common. Having my electronics protected is a peace of mind. I know of many people that have had equipment damaged - usually needs replaced. The battery back up is so nice - when the power drops off or out the home theater continues without a blink.
Summary: Cheaper UPSs will output a square wave when the main power goes out. This is NOT good for any electronics. The CyberPower PFCLCD series produces a pure sine wave, irregardless of the condition of the incoming AC.
Excerpt: Bought 10 of these as a first order to deal with the issue of sensitive PFC power supplies on my HP DC7900 small form factor PCs. My normal Cyberpower CP825 were not working with these picky power supplies and the PCs would drop and reboot on power fail even though the UPS was providing power.
- True sine wave output for active PFC power supplies
- Compact size for 850VA/510 watts capacity
- User replaceable battery
- LCD display provides useful information
- PowerPanel monitoring/configuration software is easy to use and navigate.
Excerpt: Seems like a well made product, has a small footprint, and is doing the job. (protecting my work computer and providing uninterrupted power)
I am only giving 4 stars because the true test is time (a year or so). My last ups (another brand) failed with erratic power problems after a year or so.
Excerpt: Works great. Power blips on occasion so having this has saved me thousands in repair. Have it hooked up to my pc with dual monitors and a second for my big screen and entertainment center. Gives you plenty of time to power down if power goes out for extended period of time, easy to use and setup.
Summary: Owned about 8 months, All of my PC equipment plugged into a 15 amp ground fault circuit, with the breaker in the electric panel. When you turn on a large appliance ie. Hair dryer 1200 watts ,my PC equipment would experience a "Low power spike" and freeze sometimes.
Summary: they draw power from a wall outlet, DON'T plug in without this puppy! I live in an area where "dirty electricity" is a given: Power surges, spikes, power failures, an occasional light bulb blowing blast of power when the electric company gets me back on line after a storm, and this sinewave adaptive...
