Pros & Cons

Pros

  • ✓ Pure sine wave output safe for active-PFC PCs and NAS drives
  • ✓ Up to 73 minutes of runtime at a 100W load
  • ✓ 900W usable capacity handles a full tower plus monitor
  • ✓ Six battery-backup outlets plus four surge-only for peripherals
  • ✓ Coax and Ethernet surge ports protect data lines too

Cons

  • ✗ Only 6 of the 10 outlets are battery-backed
  • ✗ 900W ceiling is tight for a high-draw GPU under full load
  • ✗ Runtime drops sharply above the 100W reference load
  • ✗ Angled LCD needs desk-level placement to stay readable

Manufacturer description

The APC Back-UPS Pro BR1500MS2 gives your desk 1500VA/900W of pure sine wave backup power, and that headroom is the point: at a 100W draw it holds up to 73 minutes of runtime, which is time enough to finish a render, close out a save, or simply ignore a short outage. Pure sine wave output matters if you run a modern PC, a NAS, or anything with an active PFC supply, since those units can misbehave on the simulated sine wave that cheaper backups produce. Ten outlets split six battery-backed for your tower, monitor, router, and NAS, and four surge-only for peripherals, plus coax and Ethernet…

SpecPicks Verdict

SpecPicks scored APC UPS 1500VA/900W 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. Prices and stock are set by the retailer and may have moved since this page was last updated.

Frequently Asked Questions

Will this run a gaming PC and monitor during an outage?

It supplies 900W across six battery-backup outlets, which covers a typical tower plus monitor. Runtime is rated up to 73 minutes at a 100W draw and falls as your load rises, so measure your actual watt draw on the LCD.

Does the BR1500MS2 output true pure sine wave?

Yes. Unlike simulated sine wave units, it delivers pure sine wave power, which is what modern PCs, NAS enclosures, and high-end home office gear expect from their power supplies.

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

Ten total: six with battery backup and surge protection for your PC, monitor, router, and NAS, and four surge-only for peripherals. It also includes coax and Ethernet surge protection ports.

Can I turn off the beeping alarm?

Yes, the alarm is silenceable. The angled LCD still shows minutes of runtime remaining, current watt draw, and battery health, so you stay informed without the noise.

Is it worth the price over a cheaper surge protector?

A surge strip does nothing during an outage. This adds battery backup plus AVR, which corrects too-high or too-low voltage without switching to battery.

Key Features

  • 1500VA/900W - POWERS YOUR FULL SETUP: Handles demanding systems with real headroom. Up to 73 minutes of runtime at 100W - enough to save work, finish a render, or ride out a short outage completely
  • PURE SINE WAVE UPS - SAFE FOR SENSITIVE ELECTRONICS: Unlike basic UPS units that output simulated sine wave, this delivers pure sine wave power. Protects modern PCs, NAS drives, and high-end home office gear from damage
  • AVR PROTECTS AGAINST BROWNOUTS & SPIKES: Automatically corrects voltage that's too high or too low without switching to battery. Protects components from slow damage caused by chronic voltage fluctuations 24/7
  • 10 OUTLETS + COAX & ETHERNET SURGE PROTECTION: 6 battery-backup outlets for PC, monitor, router, NAS. 4 surge-only for peripherals. Built-in coax and Ethernet ports protect against surges on your data lines too
  • LCD SHOWS RUNTIME, LOAD & BATTERY HEALTH LIVE: Angled screen displays minutes of runtime remaining and current watt draw. Silenceable alarm keeps you informed without the noise
