APC UPS 1000VA/600W Pure Sine Wave UPS for Computer, Electronics, BR1000MS

Bottom line: The APC UPS 1000VA/600W Pure Sine Wave UPS for Computer ($175.50 on Amazon as of 2026-10-21 16:13 UTC, orderable but not in stock): Pure sine wave output suits active PFC PSUs and DVRs that reject stepped waveforms; main trade-off: 600W usable ceiling is thin for a gaming PC plus monitor under load.

Pros & Cons

Pros

  • ✓ Pure sine wave output suits active PFC PSUs and DVRs that reject stepped waveforms
  • ✓ Up to 42 minutes runtime at a 100W load per APC's rating
  • ✓ 6 battery-backup plus 4 surge-only outlets across 10 total positions
  • ✓ AVR boosts brownouts and trims high voltage without cycling the battery
  • ✓ Angled LCD shows live watt load and remaining runtime from a seated view

Cons

  • ✗ 600W usable ceiling is thin for a gaming PC plus monitor under load
  • ✗ Replacement APCRBC160 battery is sold separately, adding cost at swap time
  • ✗ 4 of the 10 outlets are surge-only, so battery positions fill up fast
  • ✗ USB-C and USB-A share a single 5V/3A budget between both ports

Manufacturer description

The APC BR1000MS Back-UPS Pro gives your desktop, NAS, or network stack a clean power cushion when the grid drops out. Rated at 1000VA/600W, it delivers up to 42 minutes of runtime at a 100W load, which is enough to ride out a short outage or shut a workstation down gracefully instead of losing an open project. What separates this APC UPS from cheaper step-wave units is pure sine wave output: it mimics utility power closely enough for active PFC power supplies, DVRs, and sensitive audio gear that stutter or alarm on simulated waveforms. Automatic Voltage Regulation handles the quieter…

SpecPicks Verdict

SpecPicks scored APC UPS 1000VA/600W Pure Sine Wave UPS for Computer using a rating × review-volume × price-fit model applied to published specs and reviews across the power protection category. APC's power protection lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.

Common buyer scenarios for power protection of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase.

Frequently Asked Questions

How long will the BR1000MS run my equipment during an outage?

APC rates it at up to 42 minutes at a 100W load. Heavier draws shorten that considerably; the front LCD shows your actual watt load and remaining runtime in real time.

Does this UPS output true pure sine wave power?

Yes. The BR1000MS produces sine wave output that mimics utility electricity, which is what active PFC computer power supplies, DVRs, and sensitive electronics need to avoid stuttering or alarming.

How many outlets does it have, and are they all battery backed?

Ten outlets total: 6 with battery backup plus surge protection, and 4 with surge protection only. It also includes coaxial and Ethernet surge protection jacks.

Can I replace the battery myself when it wears out?

Yes, the battery is user-replaceable. The replacement is model APCRBC160, sold separately, so budget for it when the unit eventually reports a battery fault.

Will it power a gaming PC and monitor?

It supplies 1000VA/600W, so it fits typical home-office loads like a computer, router, NAS, and external drives. A high-draw gaming rig can exceed 600W, so check your system's actual wattage first.
