The best uninterruptible power supply (UPS) depends on what you need to keep running: a gaming PC, a home office, a NAS/server, or essential networking equipment.
For most people, I’d prioritize a line-interactive UPS with automatic voltage regulation (AVR), replaceable batteries, and enough wattage to handle the connected equipment. If you’re protecting expensive servers or equipment that is sensitive to power quality, a pure sine wave output or online double-conversion design may be worth the extra cost.
What are the top-rated UPS units available right now?
I need to buy an uninterruptible power supply, which ones are top-rated?
Best Upgrade / Heavy-Duty Pick for PCs & Workstations:CyberPower CP1500PFCLCD (or APC Back-UPS Pro BR1500MS2)
Specs: 1500VA / 900W to 1000W output, pure/stepped sine-wave output.
Why it’s great: High-end gaming PCs and modern desktop power supplies utilizing Active PFC require a pure sine wave UPS to prevent unexpected shutdowns or component stress when switching to battery. These 1500VA units offer enough headroom to safely save your work and shut down heavy rigs, plus informative LCD diagnostic screens.[1][2][3]
Best Value / Mid-Tier Upgrade:CyberPower CP1350AVRLCD3
Specs: 825W max output, AVR, integrated USB-A/C charging ports.
These are my top picks for different needs, based on current product listings and published reviews. Wirecutter's latest testing favors CyberPower's LE1000DG for home networking and the CP1350AVRLCD3 for larger setups.
1. CyberPower CP1500PFCLCD
(Best for most desktop PCs)
1500 VA · 1000 W · Pure sine wave
A strong all-round choice for gaming PCs, workstations, monitors, and networking gear. It combines AVR, an LCD, and battery-backed outlets. The higher watt capacity is useful for power-hungry computers.
Best balance of capacity and features.
2. CyberPower LE1000DG
(Best for home networking)
1000 VA · 714 W measured output
Excellent for a modem, Wi-Fi router, and other low-power devices. Wirecutter measured approximately three hours of runtime for a 20 W modem-and-router load.
Ideal if keeping the internet online is your priority.
3. CyberPower CP1350AVRLCD3
1350 VA · 825 W
A good upgrade for a home office with several devices. It offers AVR, an LCD, and a replaceable battery, with more output capacity than the LE1000DG.
Good for workstations and multiple peripherals.
4. Vertiv Liebert GXT5 1500VA
1500 VA · 1350 W · Online double conversion
A more serious option for critical IT equipment and servers. Online double conversion continuously conditions the output power, but costs considerably more than a consumer UPS.
Best suited to critical equipment and demanding environments.
What matters when buying a UPS?
Feature
What I'd recommend
Capacity
Size in watts based on your actual equipment draw, with headroom
Waveform
Pure sine wave for a gaming PC or sensitive equipment
Voltage regulation
AVR to handle common voltage fluctuations
Battery
User-replaceable, where possible
Runtime
Enough time to save work and shut down, or longer if needed
Monitoring
USB connection and automatic shutdown software for PCs and servers
Remember that a 1500 VA rating alone does not tell you how much equipment a UPS can power. Check the watt rating and the manufacturer's runtime chart at your expected load. Typical desktop UPS units are designed to provide minutes of backup, not necessarily hours.
Which one should you buy?
My default recommendation is the CyberPower CP1500PFCLCD for a desktop setup, or the CyberPower LE1000DG if you mainly want to keep your internet running.
To narrow it down to the best model for you, I can compare UPS models by budget or find the right UPS for my equipment.
When looking for a top-rated Uninterruptible Power Supply (UPS), the market is largely led by APC (Schneider Electric) and CyberPower . The best model for you depends heavily on whether you are backing up a high-end gaming PC/workstation (which often requires a pure sine wave output) or just standard home office gear.
The top-rated and most recommended UPS models include:
CyberPower PFC Sinewave CP1500PFCLCD ($230 $260)
Best Overall / Best for PCs & Gaming: Widely praised by tech reviewers and users as the gold standard for desktop setups. It delivers 900 W / 1500 VA of power and outputs a true/pure sine wave , making it fully compatible with modern computers that use Active Power Factor Corrected (PFC) power supplies . It features an informative LCD screen and 10 total outlets (5 battery-backed, 5 surge-only). Check availability on Staples.[1][2][3]
APC Back-UPS Pro BX1500M ($180 $200)
Best Value Heavy-Duty Backup: A massive bestseller for home offices and general workstation backup. It offers 900 W / 1500 VA of capacity with Automatic Voltage Regulation (AVR) to smooth out sags and spikes. Note that it uses a stepped approximation to a sine wave, which is fine for most routers, consoles, and standard hardware, but less ideal for sensitive high-end power supplies. View offers on Walmart.
APC Back-UPS Pro BN1050M ($110 $168)
Best Mid-Range / Compact Option: Ideal for networking gear (modems and routers), smart home hubs, or home entertainment centers. It provides 600 W / 1050 VA capacity with 6 battery/surge outlets and 2 surge-only outlets. It’s a great space-saving choice that still includes an LCD status display. Compare pricing at Best Buy.
APC Smart-UPS C SMC1500C ($560 $720)
Best Prosumer / Small Business: If you need enterprise-grade reliability for a home server, small business network closet, or critical workstation, this line-interactive, pure sine wave unit is top-tier. It includes cloud-based remote monitoring via SmartConnect. Check stock at Walmart.
To help me narrow down the best choice for your specific needs, tell me:
What devices are you planning to plug into the battery backup?
Do you know the wattage of your computer's power supply or equipment?
If you want a top-rated uninterruptible power supply (UPS), I'd start with CyberPower, APC, and Eaton. For most people, the best choice depends on whether you're protecting a desktop PC, gaming computer, Wi-Fi router, NAS, or business server.
Current 2026 reviews and product listings point to the CyberPower CP1500PFCLCD as a strong all-around option for a desktop setup, while smaller units make more sense for networking equipment alone.
