CyberPower OR1000PFCRT2U PFC Sinewave UPS System, 1000VA/700W, 8 Outlets, AVR, 2U Rack/Tower

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.

Nice UPS at a very good price. The missing star is for the missing rack mount rails. Not an issue if you are floor mounting it, but a big deal if you put it in a rack. Other CyberPower UPS's I've bought over the years came with both the rack mount ears (like this one does) and the support rails. With no rails, the back end of the UPS has no support, that's a big problem.Like similar UPS's, this one is dead silent in normal operation. It has a rated switchover time of 4 ms. That's fine for a server with a 100 ms "holdover" time. It also does transient clamping and line adjustment. Yes, there is indeed some weird combination of "UPS clamps at 627V / 2.3 us" and "server goes offline at 421V / 2.3 us". Fortunately I don't buy those sort of servers. If you buy the cheap stuff and have lots of transients, you may need a AC -> DC -> AC full time system (with the noisy all the time fans).This *is* a pure sine wave UPS. These days you do not want a "modified sine wave" UPS. You *might* get away with it, you might not. How much did that stack of servers cost ? Even if you do get away with a modified sine wave, the PFC circuits will likely be boosting the effective KVA (by trying to correct it) and you will have a tough time making sure the modified unit is rated to do what you need to do.There are a full inventory of protection add ons on the back of this UPS. You can protect a phone / ethernet line and a cable TV line (running MoCA?). There are both a DB-9 and a USB port for direct server connection. If you happen to be set up for contact closure shutdown, there's a jack for that as well.This is a 1.3KW / 2 KVA UPS. It's HEAVY, don't plan on moving it around much. 2KVA is a LOT of current on a normal 120V plug. To both run your equipment after an outage *and* charge the batteries it pulls quite a bit. It needs it's own line to get that sort of power. Take a good look at the picture of the plug on the CyberPower web site. It'a s 20A 120V plug, not the common 15A 120V plug. None of this is a knock on the product, it's the only way this sort of thing can work reliably and re-charge quickly.There's a nice LCD panel that will tell you lots of interesting stuff if you should be interested. Not as useful 3" off the floor in a rack as it might be in other mounting situations. There also is a bunch of software on a CD that will let yo access the data via the USB port. If you want to really get fancy, buy the ethernet add-on and get the data that way.Why get a different one? There certainly are a lot of UPS's out there and you can spend a lot more money on them than you do on this one. This unit will do a max load of 16.7A when running normally (no power outage). That's exactly the same as the 2KVA rating. There is no "short term overload" capability on this one. Other units *may* have a 20% short term boost. You can run for 8 minutes at full load on the OR2200. Other units have battery box add-ons that can get you into the "many hours" range if you have the money.Bottom line - this is a gizmo designed for industrial use. There are other products in the CyberPower line that are set up for normal home circuits and home use. Yes mine (I have more than one) are in my basement. I wired the basement for heavy duty use.

Nothing to complain about. Works fine. Isn't loud. Haven't yet had to rely on the battery but the status reporting works well.

Product seems to be well built, and is performing as expected. The main display shuts off after a period of time so no bright lights distract from watching tv or a movie. The price on this was very reasonable as compared to some of the competitors. I purchased this as a result of a competitors product “sacrificing” itself, leaving me with $2000 worth of scrap metal that couldn’t be repaired.

Excelente compra

Exactly as advertised. Make sure you have the proper outlet for the commercial plug.
