Ranked #5 in Best UPS Battery Backups
CyberPower CP1500PFCLCD
2 sourcesall derived$239.95as of Jul 31

The CyberPower CP1500PFCLCD is a line-interactive UPS meant to protect high-end PC systems, rated at 1500VA with an LCD that lays out power statistics in detail. Tom's Hardware found the protection reliable and the interface easy to read, while Custom PC Review flagged that the simulated sine wave output won't suit every piece of sensitive equipment. It weighs 24.7 lb and runs 14.2 inches deep, so it works on a desktop but takes up more room than some alternatives. Mid-to-high-end systems are the target; anyone who specifically needs true sine wave output should look elsewhere.

Strengths
  • — Features line-interactive topology for reliable power protection
  • — Includes LCD display showing power statistics like voltage and frequency
  • — Provides 1500VA capacity suitable for high-end PC setups
Watch-outs
  • — Outputs simulated sine wave instead of true sine wave
  • — Battery replacement kit is lower capacity (8AH) than original (9AH)
  • — Larger physical footprint compared to some competitors

Eaton 5P 1550

Eaton 5P 1550
2 sources1 derived$760as of Jul 31

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
  • — True sine wave output waveform for reliable power delivery to sensitive equipment
  • — 6 C13 outlets with programmable groups for critical and non-critical device management
Watch-outs
  • — Battery replacement requires user intervention and is not plug-and-play
  • — Limited runtime options without extended battery capability
  • — Power cord is only 6-foot length which may require additional cable management

How they stack up

CyberPower CP1500PFCLCD

The CyberPower CP1500PFCLCD offers a user-replaceable battery and LCD display, features not found in the APC Back-UPS Pro 1500VA. However, it's bulkier than the Tripp Lite SMART1500LCDT and outputs simulated sine wave instead of true sine wave, unlike the Eaton 5E 850LI which provides true sine wave output.

Eaton 5P 1550

The Eaton 5P 1550 offers a 1U rackmount form factor and true sine wave output, features not available in the Tripp Lite OMNI 1500LCD. However, it requires user intervention for battery replacement and has a shorter power cord compared to the more user-friendly APC Back-UPS Pro 1500VA.
