Eaton 5PX1000RT UPS Review

Time is money, and for businesses experiencing downtime due to electrical outages, the money lost can be astronomical. Power management and protection is paramount for small businesses and enterprises alike. StorageReview is no exception. We depend on a UPS that offers comprehensive management and power protection for the testing we do in our lab, including all servers and connected hardware, and also for accurate data testing results. The Eaton 5PX1000RT UPS is just one among many UPS products we rely on to keep our lab up and running.

The 5PX1000RT was released in 2011 with three other 5PX models, ranging up to 3000VA. Though the product is nearing its eighth birthday, it’s nothing but a testament of its reliability, durability, and sustainability. This is no surprise to us, as Eaton is known for delivering grade A products. In fact, we’ve been using a 5PX in our lab since its launch. During its time in our lab, we’ve never encountered any issues, and it’s still running strong, though we do carry out the required maintenance, as should every data center do with their equipment.

Design and Build

The Eaton 5PX1000RT is a 2U battery backup that can be configured to both tower and rack-mount, giving more flexibility to users based on available space and arrangements. Out of the box, users are able to set up both rack-mount or tower configurations with the packaged mounting kit for 19-inch bays or the tower support pedestals, respectively.

Unlike the 9PX models that feature 2 vents on either side of the center-placed control panel, the front of the 5PX1000RT UPS features, as with other 5PX models, one large vent place in the middle to act as an airflow system for cooling purposes, with the control panel being on the right-hand side of the unit.

The control panel, sporting a five-button graphical LCD, provides users with important information such as load status, events, measurements, settings, and even information about the UPS itself. The LCD will present information such as operation status, load/equipment status, efficiency and load group information, and battery status. After 5 minutes of inactivity, the LCD will display a screensaver. After 10 minutes pass, the LCD backlight will automatically dim. To restore the screen, simply press any button on the interface.

The layout of the backside of the 5PX 1000 and 1500 models are identical. On the left side, you’ll find a USB and RS232 communication port, a slot for an optional communication card, the unit fan, an LED site wiring fault alarm, and a connector for both an automatic recognition of an additional batter module and an ROO (remote ON/OFF), which allows users to remotely switch the 5PX1000RT on or off, or RPO (Remote Power OFF) control, which can remotely shut down the 5PX1000RT when the contact is open and can be used for shutting down the load and the UPS when temperatures reach a certain point.

On the right side of the rear, you’ll find x4 primary outlets and x4 programmable outlets for connecting equipment. Additionally, you’ll find the 8 ft. power cord, a connector for an additional battery module, and one more LED site wiring fault alarm.

The 5PX EBM is pretty basic in design. The front has the vent in the middle, but the LCD and other features have been removed. The back of the expansion unit has two connectors for the battery modules, which can connect to the main UPS or to the other battery modules, and two connectors for automatic recognition of battery modules. Simple and clean.


Business continuity requires effective power conditioning and protection. The tried and true Eaton 5PX1000RT UPS has consistently offered great power quality and fantastic reliability. The 5PX1000RT is the perfect solutions for small businesses needing enterprise-grade power protection. For businesses needing to be frugal with their budget, starting out with the 5PX1000RT is definitely the way to go, as you can always upgrade to the 9PX family, which can handle demands upwards of 5-11kVA, if the need arises.

At StorageReview, we have our main office/workstation cluster powered through the Eaton 5PX1000RT. This is both the room where our staff writer, Adam, works as well as where we do our workstation, consumer, and GPU benchmarking. At full charge we have 800+ minutes of uptime under light conditions, dropping in half when workstation tests are ramped up. If we are in the middle of a benchmark we can typically finish without having to start over. If our staff writer is working on a project or editing photos, he can continue unimpeded. And if the power goes out, the 5PX1000RT dashes any hopes Adam has of being able to leave early. 

The Eaton 5PX family offers capacities between 1-3kVA, which is ideal for SMB’s with a local data infrastructure. Companies looking for an easy-to-deploy datacenter power solution with impressive reliability should strongly consider the 5PX1000RT. It may end up saving you a few dollars one day. Without a doubt, the 5PX1000RT is a hardened industry UPS.
