10 Best Uninterruptible Power Supplies 2025 in the United States

The Amazon Basics UPS Battery Backup & Surge Protector provides 600VA/360W of power, making it a solid choice for home or small office use. Its power capacity is suitable for desktop computers, home networks, and entertainment systems, though it won't support heavy-duty equipment. With 8 outlets—4 surge-protected and 4 with both surge protection and battery backup—this UPS can accommodate several devices, offering basic protection against power surges and outages.

The compact design is a practical feature, allowing easy integration into tight spaces, and the 5-foot cord with a right-angle plug adds flexibility in placement. The standby UPS design means it provides power swiftly during outages, with enough battery runtime to safely shut down devices during longer interruptions. However, this type is generally not as efficient as line-interactive or online UPS systems for continuous power regulation.

Transfer time is an essential factor to consider as this UPS might not be ideal for very sensitive electronics needing immediate power continuity. The waveform type is not specifically mentioned, but typically, standby units like this provide a simulated sine wave, which might not be suitable for certain sensitive electronics, particularly those requiring a pure sine wave. The power management software is a helpful addition, giving more control over the UPS system and prolonging battery life. It's crucial to ensure that the load is kept below 80% of its capacity for optimal performance.

This UPS provides a decent balance of functionality and price for those needing basic power protection and battery backup, with the major strengths being its compact size, affordability, and sufficient outlets. However, its limitations in power capacity and waveform type might be a downside for users with more sensitive equipment or higher power needs.

The APC UPS, 1000VA Smart-UPS with SmartConnect and NMC offers reliable power backup with a capacity of 1000VA / 800W, making it suitable for small to medium-sized devices. It provides pure sine wave output, which is ideal for sensitive electronics. The unit includes 6 NEMA 5-15R battery backup outlets, allowing multiple devices to be connected simultaneously.

Its short-depth, 2U rackmount form factor is space-efficient, making it a good fit for professional environments where space is at a premium. The multi-function LCD console provides comprehensive status and control information, which enhances usability. The inclusion of a Network Management Card and SmartConnect feature allows for remote monitoring and management, improving convenience and support.

The SmartConnect feature offers a 6-month free trial, which is particularly beneficial for users new to remote UPS management. The 46-pound weight might be cumbersome for some users, but the warranty offering of 5 years for repair or replace is a strong point, ensuring peace of mind for extended use. This UPS is well-suited for IT professionals and businesses looking for a reliable and manageable power backup solution.

The Liebert GXT4 UPS with Network Card is a robust uninterruptible power supply unit designed to provide reliable power protection for critical equipment. It boasts a substantial power capacity of 6000VA/4800W, ensuring that it can support high-demand devices. The online double-conversion technology is a major strength, as it conditions power continuously without drawing on the battery, which helps extend the battery's lifespan. Additionally, the UPS provides a pure sine wave output, which is ideal for sensitive electronics that require stable power delivery. With a transfer time of virtually zero, it ensures that connected equipment remains uninterrupted during power outages.

The integrated network card allows for remote monitoring and management, which is a convenient feature for IT professionals managing multiple systems. The unit comes with hot-swappable batteries that provide up to 5 minutes of runtime at full load, and the option to add external battery cabinets can significantly extend this runtime. This makes it suitable for environments where power reliability is critical, such as data centers and server rooms.

On the downside, the product's weight and size could be a consideration for some users, as it is quite hefty and large, making it less suitable for smaller offices or home setups. Additionally, while the product was first available in 2015, it may be considered outdated as the manufacturer has already introduced a newer model, the GXT5-6000MVRT4UXLN. In conclusion, the Liebert GXT4 is a powerful and reliable UPS that is best suited for larger, professional environments where power continuity is critical, but users might want to consider the newer model for more up-to-date features.
