APC, a brand of Schneider Electric, is one of the most familiar names in home battery backups. Its Back-UPS line is the kind of box that sits under a desk and quietly takes over when the power flickers, keeping your Wi-Fi router online and giving your computer time to shut down safely. The APC 600VA model is the classic starting point, but many first-time buyers are not sure whether 600VA is enough or what VA even means.
These four models step up in size: the BE600M1 (600VA/330W) covers a router and a small PC, the BE650G1 (650VA/390W) adds more surge-only outlets, the BE850G2 (850VA/450W) adds runtime and USB charging, and the BE1050G3 (1050VA/600W) has the most power and USB-C.
APC UPS Battery Backups Compared
| Model | Capacity (VA/W) | Runtime at 100W | Outlets (battery + surge-only) | USB charging |
|---|---|---|---|---|
| APC BE600M1 UPS Battery Backup & Surge Protector | 600VA / 330W | 23 minutes | 5 + 2 | 1 USB-A, 1.5A |
| APC Battery Backup 650VA 390W Uninterruptible (BE650G1) | 650VA / 390W | 22 minutes | 4 + 4 | Not listed |
| APC BE850G2 UPS Battery Backup & Surge Protector | 850VA / 450W | 35 minutes | 6 + 3 | 2 USB-A, 2.4A shared |
| APC 1050VA 600W UPS Battery Backup (BE1050G3) | 1050VA / 600W | 36 minutes | 6 + 2 | USB-C and USB-A, 3A shared |
VA, Watts and Runtime in Plain Words
A UPS (uninterruptible power supply) is a battery plus a surge protector in one box. When the wall power fails, it switches to its battery so your gear keeps running for a short time. VA (volt-amperes) is a rating of the total electrical load the unit can handle, while watts is the real power your devices use. For shopping, the watts number is the one to compare against your equipment, and it is always lower than the VA number.
Runtime depends on load. APC gives each model’s runtime at a 100W load, which is roughly a modest desktop PC with a monitor and router, or several routers and modems together. A Wi-Fi router and modem alone often draw well under 30W, so they will run much longer than the 100W figure. A gaming PC can draw several hundred watts, so it would run for far less time.

APC BE600M1 UPS Battery Backup &
Best for: A router, modem and small PC
Pros
- 23 minutes at 100W
- 5 battery plus 2 surge outlets
- USB port works in outages
- User-replaceable battery
Cons
- Lowest 330W capacity here
- Warranty not stated in listing
The APC BE600M1 UPS Battery Backup & Surge Protector is the compact 600VA/330W model many people start with. APC says it gives 23 minutes of runtime at a 100W load, enough to keep the internet running through a short blackout and save your work before shutting down. It has seven outlets: five with battery backup and surge protection, and two surge-only outlets for less important gear like a desk lamp or printer.
A built-in 1.5A USB-A port charges a phone even during an outage. The surge rating is 490 joules, a measure of how much energy from a power spike it can absorb. Recharging the battery takes about 10 hours, and when the battery wears out you can swap it yourself with APC replacement battery APCRBC154, sold separately. The listing does not state the warranty length.
This is the right APC UPS for a router and modem, or for a laptop or small office PC plus network gear. If you plan to back up a desktop, a big monitor and a NAS (network storage drive) together, step up to the BE850G2 or BE1050G3.

APC Battery Backup 650VA 390W Uninterruptible
Best for: Desks with many surge-only gadgets
Pros
- 8 outlets total
- 3-year warranty
- Mutable audible alerts
- User-replaceable battery
Cons
- Only 4 battery outlets
- Listing mixes 550VA and 650VA
The APC Battery Backup 650VA 390W Uninterruptible Power Supply is the BE650G1. The title and description rate it at 650VA/390W, though one feature line says 550VA/330W, so the listing is inconsistent. We would trust the model’s title and description, which match. APC lists up to 22 minutes of runtime at 100W, slightly less than the BE600M1.
Its difference is outlet layout: eight outlets, four with battery backup and four surge-only. That suits a desk with many small accessories that only need surge protection, such as speakers, chargers and lamps. It has clear status indicators, audible alerts you can mute, a user-replaceable battery (APCRBC110, sold separately), a 3-year warranty and APC’s equipment protection policy for connected devices. The listing says the battery’s average life is 3 years. It does not mention USB charging ports.
Pick this if you need more total outlets than the BE600M1 but only a few devices need battery power. If you need more battery-backed outlets, the BE850G2 is the better step up.

APC BE850G2 UPS Battery Backup &
Best for: Home offices with desktop and NAS
Pros
- 35 minutes at 100W
- 6 battery outlets
- Two USB-A ports
- 3-year warranty
Cons
- Tower shape takes floor space
- Some spec fields look wrong
The APC BE850G2 UPS Battery Backup & Surge Protector is rated 850VA/450W and gives up to 35 minutes at a 100W load. It has nine outlets, six battery-backed and three surge-only, plus two USB-A charging ports that share 5V/2.4A, so you can charge a phone and tablet without using an outlet.
APC describes it as covering an entire workspace: computer, router, modem, NAS and smart home gear on battery, with printers and monitors on the surge-only outlets. It has a silenceable alarm, LED indicators, an 8-hour recharge time, a 354-joule surge rating and a user-replaceable battery (RBC17, sold separately). It carries a 3-year warranty and APC’s equipment protection policy. Some spec fields look like errors, such as an output voltage of 850 volts, so rely on the features instead. The listing calls it compact in the description but lists a tower form factor.
This suits a home office with a desktop, monitor and network gear that you want to keep running for more than a few minutes.

APC 1050VA 600W UPS Battery Backup
Best for: Bigger setups needing most headroom
Pros
- 600W, the most here
- 36 minutes at 100W
- USB-C and USB-A ports
- Floor or wall mountable
Cons
- Only 2 surge-only outlets
- More than a router alone needs
The APC 1050VA 600W UPS Battery Backup is the BE1050G3, the largest unit here. It is rated 1050VA/600W and lists up to 36 minutes at 100W. The extra wattage matters more than the extra minute: it can carry heavier loads, such as a more powerful desktop plus monitors, that would overload the smaller units.
It has eight outlets, six battery-backed and two surge-only, plus USB-C and USB-A ports sharing 5V/3A. It has a 790-joule surge rating, the highest here, an 8-hour recharge time, mutable alerts, a user-replaceable battery (APCRBC164, sold separately), a 3-year warranty and APC’s equipment protection policy. The description says it can sit on the floor or mount on a wall, which helps in a network closet.
Pick this for a bigger desk setup or a network closet with several devices. For a router alone, it is more than you need. For even larger loads, our guide to a 1500VA UPS covers the next size up.
How to Choose the Right APC UPS Battery Backup
Add up your watts. Check the power labels on the devices you want on battery and add them. Keep the total comfortably below the UPS watt rating: 330W for the BE600M1, 390W for the BE650G1, 450W for the BE850G2 and 600W for the BE1050G3.
Decide what needs battery and what needs surge only. Your router, modem and computer need battery outlets. Printers, speakers and lamps can go on surge-only outlets. Count both before buying.
Think about runtime goals. These units are for short outages and safe shutdowns, not hours of power. If you want to run a fridge or keep devices going for a long outage, a portable power station is a different category built for that.
USB charging. The BE600M1 has one USB-A port, the BE850G2 has two, and the BE1050G3 adds USB-C. The BE650G1 listing does not mention USB.
Battery replacement. All four have user-replaceable batteries with named replacement models. Batteries typically wear out after a few years, and the BE650G1 listing puts average life at 3 years.
FAQ
Is an APC 600VA UPS enough for a router?
Yes. A router and modem draw little power, so the BE600M1 should keep them running well beyond its 23-minute figure at 100W. That figure is for a heavier load.
What is the difference between VA and watts on a UPS?
VA describes the total load rating, while watts is the real power your devices consume. Compare your equipment against the watts rating, which is the lower of the two numbers.
Can the BE600M1 run a desktop computer?
For a modest desktop, yes, long enough to save work and shut down. For a high-powered gaming PC, the 330W limit may be too low, and the BE1050G3 is a safer fit.
How long do APC batteries take to recharge?
The BE600M1 lists 10 hours, and the BE850G2 and BE1050G3 list 8 hours. The BE650G1 listing does not specify.
Can I replace the battery myself?
Yes. Each listing names a user-replaceable battery: APCRBC154, APCRBC110, RBC17 and APCRBC164, all sold separately.
Which APC models include a warranty?
The BE650G1, BE850G2 and BE1050G3 listings state a 3-year warranty. The BE600M1 listing does not specify.
When connecting network storage or sensitive hardware, calculating total wattage is critical to prevent sudden shutdowns during an outage. If you plan to expand your home setup with dedicated storage solutions, consulting a detailed NAS Drive Guide helps align drive power requirements with the right battery capacity. Matching your expected runtime to your specific equipment ensures critical data stays safe until utility power returns.
