OR1000PFCRT2U PFC Sinewave UPS Battery Backup and Surge Protector, 1000VA/700W, 8 Outlets, AVR, 2U Rack/Tower, UL Certified

I bought this UPS after doing a decent amount of research and after purchasing the Cyberpower OL1000RTXL2U. The biggest difference between this UPS and the OL1000RTXL2U is that this one is a line interactive type while the latter is an online double conversion type. I am very happy with the OR2200PFCRT2U and am writing this review to help others sort out the details of determining which UPS to buy. There is a lot of noise on the Internet about this topic and since I did research it a bit and ended up experiencing both of these UPS devices, I may be able to help you make a more informed purchase.At a consumer level there are three types of UPS devices:Offline (also called Standby): Your equipment is powered by your main electrical source until a loss of power is detected by the UPS, at which point the UPS begins powering your equipment from battery.Line-Interactive: Same concept as Offline but also offering power conditioning via an inverter/converter. The addition of the inverter/converter allows for a faster switch time between normal power source and battery, better filtering of noise and spikes, and regulation of the power output to help protect equipment during brownouts and surges.Online: These UPS devices continually power all connected equipment from battery, so whether your main power is still on or whether the UPS is not connected to power, all connected equipment is always powered from the batteries in the UPS. This offers perfect protection because no matter the situation, the connected equipment gets clean power with no transfer time between source power and backup power.What I am powering from UPS: one high end computer, five 24" LCD monitors, phone, Internet modem, and wireless router.I originally bought the online type (model OL1000RTXL2U) and was nervous about the amount of noise it might generate, having read a number of reviews/forums. I bought it because I wanted all my connected equipment to be 100% immune from any kind of power fluctuation. In my situation I am working in a 12' x 13' office and the noise was way too much for me, regardless of where the UPS was placed. The fan on the UPS was continually on, and though only an 80mm fan it was designed to crank out a lot of air volume (69 cfm). The amount of air moving through such a small fan was much too loud for me to constantly put up with. Unless you can put the UPS in another room I strongly suggest going with a line-interactive UPS because to my knowledge all online UPS devices have a constant fan in order to keep the batteries cool. Online UPS devices also are about 10% less efficient in regards to power usage than typical line-interactive UPS devices.The OR2200PFCRT2U is dead silent.Although a line-interactive UPS does have a transfer time when the power source is lost, computers have a power supply that will provide what is called a "hold up" time. This "hold up" time is the amount of time that the capacitors in the power supply will remain charged so that your computer continues operating. Based upon my reading I learned that this time is typically close to 20 milliseconds, and line-interactive UPS devices often have a transfer time much less than that. For example, the OR2200PFCRT2U has a 4 millisecond transfer time, so if my main power is lost the UPS transfers over to battery in less time than the computer needs in order to observe a power fluctuation.Another important feature to consider is the type of power that the UPS delivers when operating from battery. Most computers today require pure sine wave power, which is the same power that your electrical utility supplies to your house. This means that if you are connecting a computer to your UPS, you will likely want a UPS capable of supplying pure sine wave power. Even if by chance your current computer doesn't require it, in the future you may have one that does, so you'll want to consider a UPS with pure sine wave output.The OR2200PFCRT2U tells me that when I have all the devices I listed above connected, it is at 24% of its capacity and that I have roughly 45 minutes of uptime when main power is lost. If I shut all my monitors off I have about 90 minutes.Also keep in mind that if you do experience a long running power outage you will need a generator to power your house and to therefore keep your computer running. I bring this up because unless you paid a premium for your generator it is likely that it does not produce pure sine wave power. If you plan on powering your computer from a generator during a long power outage, and assuming your generator (like most) does not produce pure sine wave power, you'll want an online UPS because even when running from generator the online UPS will power your connected equipment from its batteries. Most, if not all, online UPS devices provide constant, pure sine wave power.I have experienced two very short lasting power "blips" since hooking up this UPS and my connected equipment continued operating each time.Update on 12/20/2014: I have experienced a couple of outages at this point, one while actively working at my computer with all five monitors on. If I didn't hear the sound of items in my house turning off, I'd have not known I lost power. There wasn't anything to notice while working; the computer and monitors kept on functioning without the slightest disturbance.Another time we had a long enough outage for me to hook up my generator. It was nice to have so much time to decide whether or not to hook up the generator, as I noted above without my monitors on I have about 90 minutes to get alternative power to my computer before the UPS runs out of juice. After hooking up the generator I switched the Interlock switch on my circuit panel and turned my circuit breakers on, one by one (you should switch them all off before doing this kind of thing so that you slowly introduce a load to the generator). My circuit panel happens to be in my office, so I watched my computer and monitors while I did this, and once again I didn't notice a blip. Very nice, indeed.

I highly recommend this UPS. Good value, long battery life, high & adjustable protection. Works well in Theater Room & another Audio/Video Setup (I bought 2 of these units). Low profile, well made, many adjustable preferences & can be set to run on battery power with low noise, fans only, no beeping unless overloaded. Batteries in one of mine lasted 6.5years before wearing out. Easy to replace with CyberPower certified hot swappable battery pack. Other unit is still going strong. I’ve used many other UPS brands such as APC & TrippLite. I like CyberPower the best, though. Enjoy!

Really nice unit. Plenty of plug ins and does it's job well.

I bought this unit in December of 2021 (2.5 years ago). It's CyberPower's supposed enterprise grade line. The batteries still work fine as far as I can tell, but the unit has stopped reporting the battery percentage. When physically unplugged from the wall and under a simple resistive load, the unit consistently reads 100% for several minutes until the batteries are completely drained. So, the software which should be gracefully shutting down computers during this time thinks it has plenty of juice left. Until it doesn't, and everything cuts out. Great! The unit is still under warranty, but attempting to contact CyberPower support simply returned some bogus instructions about resetting the unit which don't even apply to this model. And even if I could reset it, how can you trust a UPS that randomly doesn't read the battery levels?? We'll see how long it takes to actually get some sort of warranty claim. I'm sure it will require paying return shipping to them, with a significant delay, while my servers sit without any UPS protection unless I go drop money on something else...

Have been using this particular unit full time since 2011; and have just purchase a brand new one. Reliable, consistent power for my workstation, and two RAID sub systems in my home office (design/ pr, marketing, audio, video); proven to keep me online and in business during brown outs, and protect gear. Proven to provide working power for my Mac Pro and RAID when power out... only had to go 20 minutes, but plenty of time to email clients, gracefully exit stuff, finish Photoshop edit, etc., before shutting all down until full power back on -- rare, but when it happens, this is the real life saver. REAL power backup, far beyond the cheap floor models which are glorified power strips (those are okay for your monitor and USB keyboard/mouse, but not a workstation class system and/or RAID with multiple drives (e.g., 4x RAID 1+0 HDD). Highly recommended; flawless; easy to read display for checking on runtime, and load.
