The short answer

Eaton 5P 1550 is the only one of the two with a published score (4.0); CyberPower OR1000LCDRM1U has none, so this is not a close call so much as an unmeasured one. Eaton 5P 1550 is best for: data center users needing rackmount protection. Read the strengths below before deciding.

Ranked #5 in Best UPS Battery Backups

CyberPower OR1000LCDRM1U

Unrated1 source$505.95as of Oct 11

The OR1000LCDRM1U is a 1U rackmount line-interactive UPS rated 1000 VA and 600 W, with automatic voltage regulation, six NEMA 5-15R outlets and an LCD that cycles through eleven power readouts. Output on battery is a simulated sine wave, which suits network gear but not active-PFC power supplies. Runtime is short — 13 minutes at half load — and remote management needs the optional RMCARD205.

Strengths

— Includes PowerPanel Business Edition software for automatic file saving and orderly PC shutdown
— Provides full automatic voltage regulation (AVR) with boost and buck functionality to maintain stable power
— Supports remote management via optional RMCARD205 adapter through standard web browser

Watch-outs

— Owners report awkward firmware updates needing serial console access, and units that would not restart unattended after an outage

Eaton 5P 1550

4.0

1 sourceall derived$290as of Oct 10

The Eaton 5P1550GR is a rackmount UPS for data center environments, rated 1550 VA / 1100 W with true sine wave output. Reviewers noted the compact 1U form factor and the 6 C13 outlets, which can be grouped programmatically so critical and non-critical equipment are handled separately. ABM battery management extends battery life and warns you ahead of a replacement. Performance is solid for the class, though swapping the battery is on the user and the included power cord runs only 6 feet. It fits anyone who needs dependable rackmount power protection.

Strengths

— 1U rackmount form factor with compact footprint suitable for data center environments
— 6 C13 outlets with programmable groups for critical and non-critical device management
— Optional Gigabit Network Card (Network-M2) adds network manageability features

Watch-outs

— Battery replacement requires user intervention and is not plug-and-play
— Limited runtime options without extended battery capability

Derived means the reviewer published no score, so one was inferred from their written verdict. Everything else is a number the publisher printed. How we rank.

How they stack up

CyberPower OR1000LCDRM1U

Against an APC unit of similar capacity this is usually the cheaper route to a rackmount UPS with a real diagnostic display, and it gives up pure sine wave output and some firmware polish to get there. Anything with an active-PFC power supply, which covers most modern desktops and servers, wants a sine-wave model instead.

Eaton 5P 1550

The Eaton 5P 1550 is a 1U rackmount unit with true sine wave output, where the CyberPower OR1000LCDRM1U, also a 1U rackmount, puts out a simulated sine wave. It is rated 1550 VA and 1100 W against that CyberPower's 1000 VA and 600 W, and it costs less. Its input defaults to 230V and its outlets are 6 C13, where the Tripp Lite SMART1500LCDT is a 120V tower with 10 outlets.
