APC BR1500G
2 sourcesall derived$339.79as of Oct 11

The APC Back-UPS Pro 1500G is a line-interactive UPS for power users and small businesses, rated 1500VA/865W with 10 outlets, 5 of them battery-backed. Reviewers liked the solid build quality and the bundled PowerChute Personal Edition software for monitoring, but several found 5 battery-backed outlets too restrictive. Output is stepped sine wave, and the battery is replaceable under a 3-year warranty. Reviewers rated its performance well; the sticking point is EU pricing, which looks poor next to US availability.

Strengths
  • — 1500VA/865W capacity suitable for mid-range desktop setups
  • — Line-interactive topology with voltage regulation capabilities
  • — Includes PowerChute Personal Edition software for monitoring and diagnostics
Watch-outs
  • — Only 5 of the 10 outlets are battery-backed, and retailer listings disagree on the exact count
  • — Higher price point in EU market compared to US
  • — Internal fan causes somewhat high noise levels during operation

Eaton 5P 1550
Ranked #4 in Best UPS Battery Backups
Eaton 5P 1550
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

Like the Tripp Lite it has 10 outlets with 5 battery-backed, where the CyberPower CP1500PFCLCD lists 12 outlets. Its output is a stepped approximation to a sine wave, while the Tripp Lite lists sine wave and the Eaton 5P 1550 true sine wave, and it costs more than the CP1500PFCLCD.

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.
