benchmarksutra UPS Score: How We Rate UPS for Computers
Summary

How benchmarksutra rates uninterruptible power supplies: maker-stated specs and Indian prices only, nothing guessed.

Quick Verdict

The benchmarksutra UPS Score rates 13 uninterruptible power supplies sold in India. Every spec comes from the maker's own product page, and every price from an Indian retailer's listing. We never use test results from other sites, and we never fill a gap with a guess.

Researched, not hands-on tested. Scores use only the specifications on each maker's own product page (checked 16 November 2026) and prices at Indian retailers (checked 16 November 2026). We did not test these uninterruptible power supplies ourselves. How the benchmarksutra UPS Score works.

What we rate

  • Rated power. Rated power in watts, against the strongest UPS in the same size class (600–650 VA or 1,000–1,600 VA). Watts, not VA, decide what you can plug in.

  • Mains voltage window. The mains voltage range the maker says the UPS runs on before it switches to battery: a 120 V wide window rates 0, 170 V or wider rates 100. A wider window means fewer switches to battery during Indian voltage dips.

  • Battery-backed outlets. Outlets the maker lists as battery-backed: 2 rate 25, 3 rate 50, 4 rate 75, 5 or more rate 100.

  • Computer data port. A USB or serial data port the maker lists for connecting the UPS to a PC: listed rates 100, none rates 0.

  • Warranty. Warranty the maker states: 2 years rates 50, 4 years 100.

  • Price. Lowest price we found, against the cheapest UPS in the same size class.

Buyer profiles

ups comparison chart by benchmarksutra

What we checked

We read each maker's own India product page or datasheet for rated power in watts, the mains voltage window, the outlets that run on battery, a USB or serial data port and the warranty. Every UPS here is stocked by at least one of our partner stores (MD Computers, Computech), so the price and the buy links come from them, cheapest first. Where a maker page does not state a rated item, that row scores zero; we never guess.

Two size classes

A 600 VA UPS and a 1,500 VA UPS do different jobs, so rated power and price are compared only within the same class: 600–650 VA for one PC and a router, and 1,000–1,600 VA for a gaming PC or a workstation with a monitor.

What we show but do not score

Battery size and backup time are shown where the maker states them, but not scored, because makers quote them in different ways (battery ampere-hours, battery voltage only, or minutes at a load of their choosing) and some state none. Every UPS here gives a stepped, simulated or modified sine wave on battery, so the waveform does not separate them. BIS certification is mentioned where the maker states it. Our guide to home inverters covers whole-house backup, which is a different job.

What we do not rate

Real backup time with your PC, switching behaviour and battery life need tests. We do not run them and we do not use other sites' results.

What the score does not measure

  • Real backup time with your own PC.

  • How the battery holds up after a year or two.

  • Noise and heat.

What we left out, and why

Reason

Products

Fingers' website loads its product pages only in an app view we could not read, so there are no maker-stated specs to score.

2

Luminous's India website does not list its LB-series computer UPS, so there is no maker spec page to score from.

2

We found no EVM product page for this UPS, so there are no maker-stated specs to score.

2

Maker states fewer than 4 of the 6 rated specs
