Choosing between two rackmount UPSs for critical power isn't just about VA ratings. The Eaton 5P 1U Rackmount 208V/240V 1550 VA/1100W and the CyberPower OR2200LCDRT2U Rackmount Smart UPS 2200VA 120V take two very different paths to the same goal: keeping your rack online when the mains drop. One is a new, slim unit for higher-voltage racks; the other is a used, taller unit built around standard 120V power with a bigger VA number.
Quick verdict
If you need a new 1U UPS that fits a 208/240V rack environment, the Eaton 5P is the straightforward pick. If you're on a standard 120V circuit and want more VA capacity, an LCD display, and automatic voltage regulation, the CyberPower is the one that lines up - at a lower listed price.

Where each product wins
- Eaton 5P - Choose it when your rack uses 208/240V and you want a new, slim 1U unit with six C13 outlets and high-efficiency operation. It's the tidier fit for higher-voltage enclosures.
- CyberPower OR2200LCDRT2U - Choose it when you're on a standard 120V circuit and want the larger 2200VA rating, LCD status display, AVR, and surge protection. The lower listed price and bigger VA number make it the capacity pick.
Product notes
Eaton 5P 1U Rackmount 208V/240V 1550 VA/1100W Uninterruptible Power Supply UPS
The Eaton 5P is a line-interactive UPS in a 1U rackmount form factor, rated at 1550 VA and 1100 W of continuous output. It's listed as new and supports 200-240V, so it's designed around 208/240V rack power rather than residential 120V. The unit includes six C13 outlets, a DB9 serial adapter, a plastic front trim panel, and high-efficiency operation above 95% in its efficiency mode. At USD 289.99, this is the more expensive of the two units, but you're getting a new, compact piece of hardware. The limitation is the voltage side: if your rack runs on 120V mains, this Eaton's input range won't match your setup, and 1100 W is the specified output ceiling.
CyberPower OR2200LCDRT2U Rackmount Smart UPS 2200VA 120V Battery Backup
The CyberPower OR2200LCDRT2U is a 2U rackmount smart UPS rated at 2200VA and built for 120V installations. It's listed as used, and it brings an LCD status display, audible alarm, automatic voltage regulation, surge protection, and USB plus serial communication ports to the rack. If your critical equipment runs on standard 120V and you want to monitor status from the front panel, this unit checks those boxes while showing a lower listed price of USD 184.98. The trade-offs are the used condition and the 2U height, which takes up more vertical space than the 1U Eaton in a crowded rack. For a 120V environment where VA capacity matters more than a slim footprint, this is the more practical direction.
Final choice by use case
Pick the Eaton 5P when you're outfitting a 208/240V rack, need a new unit, and want to keep the height to 1U. Pick the CyberPower OR2200LCDRT2U when your rack is on 120V, you want a larger VA rating, and you're comfortable with a used unit that offers LCD monitoring and AVR. For most standard-voltage server setups, the CyberPower gives you more rated capacity for a lower listed price; for higher-voltage installations, the Eaton is the cleaner fit.
