CyberPower OL3000RTXL2U Smart App Online UPS System, 3000VA/2700W, 7 Outlets, 2U Rack/Tower

For what it is, this unit is great. It is supposed to be rack-mounted at a data center, where airflow is king and noise is no big deal. So far, I'm impressed with the unit, but it is definitely not meant for residential operation. I had a Cyberpower "line interactive" model that was far less expensive, and the first time a solid storm came along while I was using my computer - pow! there goes my PSU and who knows what else inside the PC took a hit. If you're using a line-interactive UPS, get rid of it now. It may work fine for power sag, but it has a several-millisecond cutover time from line to battery, and that is far too long - the damage is already done. You need an "online" UPS - one that runs all of the connected equipment on battery power at all times, period. My advice to Cyberpower would be to create a residential unit that is sized to handle all the load a 15 or 20-amp circuit could throw at it, but in a form factor that is better for residential usage, and without the need for a 70CFM fan running at full blast all the time. When this thing switches to battery power, it sounds like an absolute wind tunnel when both high-static pressure fans fire up at the same time. During standard operation, there is a single 70CFM fan blowing (probably at max RPM) at all times, and in a quiet office, it is distracting. In a residential setting, the unit will be installed in a much cooler, much quieter, and much less cluttered environment. They could repackage this in a form factor that would allow a nice 140mm magnetic bearing fan that would run dead quiet most of the time. If they made a fully-online model that could handle say 1800 watts (15 amp circuit, 120 volts), or 2400 watts (20 amp circuit, 120 volts), but with no option to expand, and no rack-mount rails - well that would be the perfect home office UPS. I hope Cyberpower reads these reviews!

Very simple to set up and use, and has been operating flawlessly. It's a "double-conversion" type, designed to run on generator power during power outages, which is why I bought it (no outages since I installed the unit, so I can't report yet on how well that works). Very solid, robust physical construction (weighs 40 pounds!).I also bought the RMCARD302 network card for it, so I can check its status via web browser from any of the 3 PCs that I have hooked up to it. My router automatically assigned it an IP address (shown on the router's Status page), so I was able to access it right away, with no fuss. It comes with "Power Panel Business Edition" software, so I installed that on one of my PCs, but found it to be unnecessary and in fact overkill for my simple installation, so I uninstalled it. The network card has its own user interface, which I find more than adequate.Yes, the cooling fan is fairly loud. I do lots of audio work on my PCs, and I need a quiet environment, so my CyberPower unit is installed in the basement, with extension cords running up to my 3 PCs. And the PCs themselves are low-power fanless units (from SuperLogics). Problem solved!Update (9/5/16): I can now report that this unit performs flawlessly in the event of a power outage. I was editing some audio files on my PC late at night when the outage occurred. The room suddenly went black, but my PC didn't even blink! Then 20 seconds later my generator kicked in and the lights came back on. Several hours later, the utility power was restored and the generator stopped. My PC continued to operate normally through all of this, as if none of it ever happened! The CyberPower unit was configured in Generator Mode (as opposed to Normal Mode) with Power Fail Conditions being anything outside of 95-150VAC and 60 Hz +/-10%. These settings evidently worked, and I can now recommend this CybePower UPS without reservation.

I wanted a true inverter UPS for my home theatre equipment as I am about to have a whole-home generator installed, and wanted to make sure that the UPS was capable of providing clean power to the equipment. After reviewing products from several companies, I realized this model from CyberPower was going to give me the best features at the best price.This unit is typically designed to be rack mounted, but i have mine sitting on the bottom shelf of the table that holds my AVR and other associated electronics. Some have indicated that the fans on this unit are loud, but I have not found them noticeable at all except when it is totally quiet in the house, and even then, the fan noise is barely noticeable.While this type of UPS is much more expensive than others with similar capacity, it is a fraction of the cost of the equipment connected to the device. Highly recommended.

Seems like it would be a great system but it is unusable unless you have aspecial outlet that I was not told or not mentioned in the description so watch out. You need an electrician to install the unit.

If you are looking for a double conversion UPS that does the job without breaking the bank this unit is for you.All the controls can be accessed without connecting to a computer or network. I am using this ups without being connetedto any computer. This unit is very big. It is also very heavy. This ups is built like a tank. It is rack mountable or youcan set it up as a tower with the tower stand provided. That is a very nice gesture from cyberpower because most manufacturestower stands are optional at a price of $75-$120.00. With this unit they are free which is a big deal.The OL1000RTXL2U has a cooling fan that is always on. The fan is as loud as an hunter whole room air purifier on medium or the number 2 setting.Which means the fan is pushing a good volume of air. Will the fan bother most people? It depends where you put it. But I would say no. This upshas no problem syncing to a generator. Because of the fan this ups never gets hot with 24/7 operation. According to the manual it is required to docleaning of filters or inflow screens every so often. The unit has performed flawlessly for 4 months now. It is a great unit.
