Finding the best UPS battery backups for computers and Wi-Fi gear starts with one question: what are you protecting, and what do you need it to do when the power drops? For most home setups the answer is a safe shutdown for a PC, plus a router or modem that stays up a little longer. This guide compares five UPS units on manufacturer specs and independent expert recommendations, so you can match capacity, output type and features to your desk.
A quick caveat before the picks: every unit here lists only a few minutes of runtime at full load. A UPS like this is meant to bridge short dropouts and give you time to save work and shut down cleanly, not to run a full desk through a long outage.

The LCD shows input voltage, output voltage, frequency, load percentage, load watts, battery voltage and runtime in minutes. AVR corrects brownouts across 92-150V without using the battery. A USB HID-compliant port works with PowerAlert software for automatic file saves and graceful system shutdown. Dedicated Tel/DSL and Ethernet dataline protection is included, which is useful if your modem or router connects over those lines. It has 10 outlets (5 battery-backed, 5 surge-only) and runs at less than 36 dB.
Runtime is 2.3 min at full load (900W) and 10 minutes at half load (450W).

It is recommended in 7 expert guides.

How to Choose a UPS for Your Computer and Wi-Fi
Match capacity to your load
Add up the wattage of what you plan to put on the battery-backed outlets, then compare it with the unit's watt rating, not just the VA figure. The 850 VA / 510 W EC850LCD and the 425 VA / 260 W ST425 suit lighter setups, while the 1500VA units are for desktops with monitors and network gear.
Check the output type
Pure sine wave output, as on the CP1500PFCLCD, is the safer match for PCs with PFC power supplies. The other four units list simulated sine wave output or do not specify the waveform, so confirm your power supply's requirements before buying.
Expect minutes, not hours
All five units list 1.5 to 2.8 minutes at full load. Lighter loads last longer, and a router or modem alone draws far less than a gaming PC. The goal is a clean shutdown and ride-through of brief dropouts.
Look at the extras that matter to you
AVR (on the CP1500PFCLCD, SMART1500LCDT and BX1500M) corrects voltage swings without using the battery. Software and USB management help with automatic shutdown. Dataline protection and coax or RJ45 ports matter if your modem connects that way. A user-replaceable battery, as on the APC, lowers long-term upkeep. Also consider weight: the 1500VA units run roughly 24 to 25 lbs.
How We Picked
This guide is based on manufacturer specs and independent expert recommendations, not hands-on testing. We narrowed the field to five using manufacturer specifications, the number of expert buying guides recommending each product, and published expert review scores where available. Pros, cons and best-for notes reflect those specs and what independent reviews consistently say. We do not list prices, because they change; use the check price buttons for current offers.
Bottom Line
For most people with a gaming PC or workstation, the CyberPower CP1500PFCLCD is the safest choice thanks to pure sine wave output, 1500VA/1000W capacity and strong expert backing. If you want detailed monitoring and network dataline protection, choose the Tripp Lite SMART1500LCDT. For an easy-to-maintain home office, the APC BX1500M offers a replaceable battery. On a tighter budget, the CyberPower EC850LCD covers a basic PC and router, and the compact ST425 is best kept to light loads like a modem and router.

Frequently asked questions
Which UPS here has the longest runtime at full load?
The APC Back-UPS Pro BX1500M: 2.8 minutes at full load (900W). The CyberPower CP1500PFCLCD lists 2.5 min, and the Tripp Lite SMART1500LCDT and CyberPower EC850LCD list about 2.3 minutes. All are meant for safe shutdowns rather than long outages.
Which UPS is best for a gaming PC with a PFC power supply?
The CyberPower CP1500PFCLCD: it offers pure sine wave output, which suits PFC power supplies in modern gaming PCs and workstations. It also has 1500VA/1000W capacity, though runtime is only 2.5 min at full load.
Which UPS is best for a router and modem?
The CyberPower ST425: it is a compact standby UPS suited to light loads such as a modem, router or basic computer. For a basic PC plus a router, the CyberPower EC850LCD has more capacity at 850 VA / 510 W.
Which UPS has the most outlets?
The CyberPower CP1500PFCLCD and the CyberPower EC850LCD: 12 outlets each, with 6 battery-backed and 6 surge-only. The Tripp Lite and APC 1500VA models have 10, and the ST425 has 8.
Which UPS has a battery I can replace myself?
The APC Back-UPS Pro BX1500M: it has a user-replaceable, hot-swappable lead-acid battery, which minimises downtime. The trade-off is a 16-hour recharge time.
Does a UPS keep Wi-Fi running during an outage?
A UPS can keep a router or modem running if they are plugged into battery-backed outlets, but only for the runtime its battery allows. Lighter loads last longer, so a router alone will outlast a full desktop, but none of these units is meant for extended outages.
