Best UPS battery backup for a home

Three units, one each for what must stay on: the network, a home office desk, and a gaming PC with a power supply that needs a real sine wave. Every figure is the maker's, and none is a test of ours.

A UPS does one of two jobs. For a modem and router it is a small battery that keeps the Wi-Fi up through the outage: APC's chart gives the BE600M1 1 hour 22 minutes at 33 W. For a computer it is a bridge: enough minutes to save, close and shut down before the battery runs out. Buying the big one for the router wastes money; buying the small one for the PC loses work.

The three below cover the network, a home office and a gaming PC. The router guide sizes the first job from the adapter label, and APC vs CyberPower puts the two makers' own statements side by side.

APC publishes a runtime chart by watts; CyberPower publishes half and full load only, so the two columns are not on the same terms. Every figure is the maker's with new batteries, not a HoldBackup test. The equipment policies are the makers' programs with their own terms, not warranties.

APC BE600M1

Sold as: APC BE600M1 UPS Battery Backup & Surge Protector for Computer, Router, NAS

APC publishes five battery-backed outlets and a 600 VA / 330 W rating for the BE600M1. Use its runtime chart at your connected load, then check adapter spacing and the equipment’s waveform requirements. Its standby design is a candidate for a basic network setup, not proof that every modem, router or desktop will work with it.

It is the one box on this page that covers the first job for almost every home. 1,000 W of pure sine wave output rides a desktop, a NAS, or a modem and router through the flicker, and its line-interactive voltage regulation corrects brownouts without draining the battery. CyberPower's chart gives 100 minutes at 50 W and 23 minutes at 300 W: minutes to shut down cleanly, not an evening of power.

  • Active PFC power supplies, which some UPS units trip

Skip if

  • You need hours rather than minutes
  • The load has a motor: a fridge, a pump, a furnace blower
  • You want something light: it weighs about 25 lb

APC Back-UPS Pro BR1500MS2

Sold as: APC BR1500MS2 Pure Sine Wave UPS Battery Backup & Surge Protector | 1500VA/900W Back-UPS Pro sinewave UPS for PC, Gaming, electronics. 10 Outlets. USB-C charging

The APC for a gaming PC or a loaded desk: a sine wave inverter, so a power supply with active PFC never sees the stepped output APC itself warns about, and voltage regulation that corrects sags without switching to battery. APC's chart gives 36 minutes at 200 W and 7 minutes 55 seconds at 600 W, which is time to save and shut down, not to keep playing. Six outlets are backed, four are surge only, two USB ports charge a phone, and the APCRBC163 cartridge is user-replaceable.

One sine wave UPS with voltage regulation for a gaming PC or a loaded desk.

HoldBackup earns a commission if you buy through this link. Amazon sets the price.

Best for

  • A gaming PC or a workstation with an active-PFC power supply
  • A desk with a monitor, a console and a router on one unit
  • Brownouts: voltage regulation works without draining the battery
  • Replacing the battery yourself when it wears out

Skip if

  • You run macOS or Linux: APC's shutdown software is Windows only
  • You want minutes of gaming, not minutes to shut down: 600 W lasts under 8 minutes by APC's chart
  • You only need a router: this is far more UPS than the job

How we chose

  1. What must stay on, and for how long: a router for hours, a desk for the minutes it takes to save and shut down.
  2. Output waveform against the load: a stepped wave for adapters, a sine wave for any computer power supply with active PFC, as both makers advise.
  3. Topology: standby for the network, line interactive with voltage regulation where brownouts are common.
  4. Runtime as the maker publishes it, at a stated load.
  5. A user-replaceable battery, because every UPS battery wears out.
  6. Software that runs on your operating system, from the maker's own compatibility notes.
  7. Warranty and the equipment protection policy as stated for the US.

Every number is the maker's, from the spec page or manual linked beside it. HoldBackup has no lab, so nothing on this page was tested by us, and Amazon sets the price the button shows.

Owner lines summarize public forum threads, linked beside them. We don't verify what owners say.

Questions

Does a modem and router need a pure sine wave UPS?

No. A router's power adapter is a small switching supply that runs on a stepped sine wave, and APC sells its small standby units for exactly that job. Pure sine wave matters for a computer power supply with active power factor correction, which both makers say can misread a stepped waveform's zero point as a power failure.

How long will a UPS run my computer?

Minutes, not hours. APC's chart for the BR1500MS2 gives 36 minutes at 200 W and under 8 minutes at 600 W; CyberPower gives 10 minutes at half load for the CP1500PFCLCD. A UPS buys the time to save and shut down cleanly. For hours, look at a power station.

What does VA mean, and why is the watt figure smaller?

Volt-amperes are the apparent power the UPS can carry; watts are the real power your gear draws. The watt rating is the one to size by. A 1,500 VA unit from APC is rated 900 W and from CyberPower 1,000 W, and near that load both makers' figures fall to minutes.

Can I plug a laser printer or a space heater into the battery outlets?

No. APC's support page says not to plug a laser printer into a UPS at all, battery or surge-only outlets, because its current draw can sag the line and run the battery down, and a 1,500 W heater draws more than any unit here carries. Put the computer, the monitor and the network on the battery outlets.

Where does the price button go?

Straight to Amazon. Amazon sets the price and availability, and both can change.
