Which APC UPS is best for a computer?
The APC BR1000MS is the best fit for many desktop computers because it combines a 600W limit, pure sine wave output and 6 battery backed outlets. For another brand's models, compare our Eaton UPS battery backups.
The BR1350MS is a better match when the measured load needs more room, while the 900W Smart-UPS models fit monitored or rack based setups.
We compared the stated capacity, outlet layout, monitoring features and form factor for each model.
Our score weighs specs, features and buyer feedback against what you're shopping for. A UPS's runtime changes with the connected load, so don't treat a low load runtime figure as a guarantee for a desktop.

How much UPS capacity does a computer need?
A computer UPS needs a watt rating above the combined draw of the computer and the devices you plan to keep powered. Check the computer's power supply label as a starting point, then use a watt meter or system monitoring tool to estimate actual draw during the work or game you care about.
VA capacity alone is not enough to compare models because VA and watts are different ratings. In this group, the useful watt ceilings are 600W, 810W and 900W, so choose by the actual load and keep a margin for brief peaks.
A gaming desktop can draw much more power under load than when idle. Include the monitor and router in your estimate if they also need to stay on, and avoid plugging a laser printer or other high draw equipment into battery backup outlets.
For a laptop, the adapter usually draws less than a desktop gaming PC, but you may prefer a smaller UPS with the router included. Our guide to the best UPS for a gaming laptop covers that different setup.
What outlets should go on battery backup?
Put the computer and monitor on battery backup outlets so you can save files and shut down when power fails. Add a router or external storage device only if continued network access or a clean storage shutdown matters to your setup.
The BR1000MS and BR1350MS divide 10 outlets into 6 battery backed outlets and 4 surge only outlets. The gaming model uses the same split, while the Smart-UPS tower lists 8 output outlets and the rack model lists 6.
Surge only outlets protect connected devices from surges but do not provide battery runtime. Keep optional peripherals there and reserve battery outlets for the equipment that needs time to shut down.
Do not connect more equipment simply because outlets remain open. The total watt draw still has to stay within the UPS capacity.
Does a computer need pure sine wave output?
Pure sine wave output is a useful feature for a modern computer power supply, especially in a gaming or workstation setup. Each model in this roundup is described as a pure sine wave UPS, and that output is one reason these APC choices suit computers.
A UPS can also correct some voltage changes without switching to battery, depending on its features. The BR1000MS, BR1350MS and Smart-UPS models include automatic voltage regulation, which adjusts high and low voltage.
Choose based on the computer's requirements and total draw rather than assuming that a larger VA number alone means a better fit.

The Plain Answer](/what-is-a-dc-ups-system/).
What is the difference between APC Back-UPS and Smart-UPS?
The Back-UPS Pro models in this guide are tower units for home and desktop setups, with 10 outlets split between battery backup and surge only power. The Smart-UPS models provide 900W capacity and SmartConnect remote monitoring, with one tower and one rackmount form.
The better choice depends on how you use the computer. A home desktop may not need remote monitoring, while a rack or network room can benefit from rack mounting and remote status checks.
If you're comparing the APC BR1500MS2 with another 1500VA UPS, see APC BR1500MS2 vs CyberPower CP1500PFCLCD: Which Should You Choose?. The BR1500MS2 is not one of the models in this roundup, so check its exact outlet layout and capacity separately.
Is the APC BE600M1 the same as these 600VA models?
No, the APC BE600M1 is a distinct 600VA model, while the BR1000MS in this roundup is rated at 1000VA and 600W. Search phrases such as “APC Back-UPS 600VA BE600M1” and “600VA UPS APC” refer to a different capacity class.
Do not choose a UPS from a search phrase alone. Compare the full model number, watt rating, outlet count and battery backup arrangement before deciding whether it can support your computer.
How should you plan for shutdown time?
A UPS should give you enough time to save work and shut down, not to keep using a desktop through a long outage. The BR1000MS provides up to 42 minutes at a 100W load and the BR1350MS up to 54 minutes at 100W, but a computer and monitor can draw far more than 100W.
Enable any compatible shutdown software and connect the UPS data cable if the model supports it. Close open work, save files often and keep a backup of important data, since battery runtime falls as load rises.
Which APC UPS should you choose for your computer?
Choose the BR1000MS if your computer setup stays below 600W and needs six battery backup outlets. Pick the BR1350MS for more capacity up to 810W, the 900W Smart-UPS tower for SmartConnect monitoring, or the rackmount model when rack space is part of the setup.
For a gaming rig, the Back-UPS Pro Gaming model offers the same 900W ceiling with a gaming focused display and lighting. Whichever you choose, verify the total load and put only essential equipment on battery backup.

Frequently asked questions
How do I choose an APC UPS for my computer?
Choose by the computer and monitor's combined watt draw, then leave headroom below the UPS maximum. The BR1000MS supports up to 600W, the BR1350MS up to 810W, and the 1500VA models up to 900W.
Also count the devices that need battery backup, not just surge protection.
How many UPS outlets does a computer need?
Count the computer, monitor and any router or storage device you want to keep running during an outage. The BR1000MS and BR1350MS have 6 battery backup outlets plus 4 surge only outlets, while the rack Smart-UPS has 6 outlets.
Put essential devices on battery backed outlets.
Can an APC UPS shut down a computer automatically?
Some APC UPS systems support computer shutdown when connected to compatible management software and a data connection. Check the specific model's included connection and software support, then configure the operating system to save work and shut down before the battery is depleted.
A UPS gives you time to act, not an unlimited power supply.
Is a 600VA APC UPS enough for a computer?
VA and watts describe different limits, so compare the computer's draw with the UPS watt rating. The APC model often searched as the BE600M1 is a different 600VA class than the 1000VA/600W BR1000MS in this guide.
Check the exact model number and its watt capacity before buying.
