If your network gear is the one thing that absolutely cannot go dark, the BE425M earns its spot on a short list. This compact APC unit splits its outlets between battery backup and pure surge protection, so you can dedicate backed-up power specifically to a router and modem while surge-only outlets handle secondary gear. At a 100W load it holds roughly 15 minutes, plenty of runway to keep a connection alive through a short blip or shut down cleanly during a longer one. The 180-joule surge rating adds a layer of defense against the electrical spikes that quietly wear down networking hardware over time. What makes it stand out for this use case is the Building Wiring Fault Indicator, a safety check most competing units skip entirely. Its small footprint means it tucks behind a router or modem without stealing desk space. For anyone whose priority is uptime for connectivity rather than powering a full workstation, this is a lean, purpose-built option.

Buying Guide: What to Look for in a UPS for Network Equipment
VA Capacity and Runtime
VA (volt-ampere) rating determines how much load a UPS can handle and for how long. For a basic home network with just a router and modem, a 425VA unit like the APC BE425M UPS Battery Backup and Surge Protector or the CyberPower ST425 Standby UPS Battery Backup delivers up to 15 minutes of runtime at a modest load, which is plenty of time to ride out a brief outage.
If you’re running a NAS, a managed switch, and multiple access points, step up to a 1500VA model. Units like the APC BX1500M UPS Battery Backup & Surge Protector can sustain your full network rack for over an hour at lighter loads, giving you real breathing room during extended outages.
Topology: Standby vs. Line-Interactive
Standby UPS units are the most affordable option. They sit idle until power fails, then switch to battery. That brief transfer time is usually imperceptible for routers and modems, making units like the CyberPower ST425 a solid value pick for basic home networking.
Line-interactive units, such as the CyberPower CP1500AVRLCD3 Intelligent LCD UPS, use Automatic Voltage Regulation (AVR) to correct brownouts and overvoltages without ever touching the battery. This matters a lot if your area sees frequent voltage sags, since those chronic fluctuations cause long-term damage to networking hardware. For a deeper look at the gear these UPS units protect, browse our best access points for home roundup.
Pure Sine Wave vs. Simulated Sine Wave
Most network gear runs fine on simulated sine wave output. Routers, modems, and unmanaged switches are not particularly sensitive to waveform shape, so a simulated sine wave UPS gets the job done at a lower cost.
However, if your network rack includes a NAS with modern power supplies or any Active PFC equipment, pure sine wave output is the safer choice. The APC BR1500MS2 Pure Sine Wave UPS Battery Backup is purpose-built for this use case, delivering clean power that won’t stress sensitive components during the switch to battery.
Outlets, Data Line Protection, and Charging Ports
Count your connected devices before choosing a unit. Network setups often include a router, modem, switch, NAS, IP camera, and maybe a VoIP adapter. A UPS with only four battery-backed outlets can fill up fast. The APC BR1500MS2 and APC BX1500M both offer ten total outlets, with dedicated battery-backup positions for your most critical gear.
Built-in Ethernet and coax surge protection is worth paying attention to. Surges travel through data lines just as easily as power lines, and many people overlook this. Models like the APC BX1500M and APC BR1500MS2 include both coaxial and Ethernet surge protection ports, which adds a meaningful layer of defense for your network infrastructure. A USB charging port is a handy bonus that lets you keep a phone or tablet powered without using a protected outlet. If you’re expanding your home network alongside a new UPS, our guide to the best modem router combo units is worth a read.
Final Thoughts
For most home network setups, the APC BE600M1 UPS Battery Backup & Surge Protector hits a practical sweet spot with reliable battery backup, solid runtime, and a USB charging port in a compact form factor. If you’re running a more demanding setup with a NAS or Active PFC equipment, the APC BR1500MS2 Pure Sine Wave UPS Battery Backup is the clear upgrade, delivering clean pure sine wave output, AVR, and enough capacity to keep a full rack alive through nearly any short-term outage.
Frequently Asked Questions
Do I really need a UPS for my home router and modem?
If you work from home, rely on VoIP calls, or simply can’t afford unexpected downtime, a UPS is worth it. Even a compact 425VA unit keeps your router and modem running through short outages and protects them from the voltage spikes that quietly degrade hardware over time. In 2026, with so many households depending on a stable connection for work and school, it’s a low-cost insurance policy that pays for itself quickly.
How long will a UPS keep my network running during a power outage?
Runtime depends on the UPS capacity and the total wattage of your connected devices. A 425VA unit powering just a router and modem can typically sustain them for 15 to 20 minutes. A 1500VA unit running the same light load could last well over an hour. The key is to calculate your actual load and match it to the UPS wattage rating rather than just the VA number.
What is the difference between a standby UPS and a line-interactive UPS?
A standby UPS stays inactive until power fails, then switches to battery within a few milliseconds. A line-interactive UPS actively regulates incoming voltage using AVR, correcting brownouts and overvoltages before they reach your equipment, without depleting the battery. For network equipment in areas with unstable power, line-interactive is the better long-term choice. You can learn more about protecting your full home network setup in our guide to the best WiFi extenders for gaming, which pairs well with a solid backup power strategy.
Can I use any UPS with a NAS drive?
Most modern NAS devices use power supplies with Active Power Factor Correction (Active PFC), which can behave unpredictably when paired with a simulated sine wave UPS. For NAS drives, a pure sine wave UPS like the APC BR1500MS2 is strongly recommended to avoid potential data corruption or hardware stress during the switchover to battery. Always check your NAS manufacturer’s documentation for power supply compatibility before choosing a UPS in 2026.
