10 Best Ups Backups 2025 in the United States

The Amazon Basics Line Interactive UPS is designed to offer a reliable power backup solution for home and office electronics, making it suitable for users looking to protect their devices from outages and surges. With a power capacity of 1000VA and 550W, it provides decent support for multiple devices, thanks to its 9 outlets, which include both surge-protected and battery-backup options. This could be particularly beneficial for anyone looking to keep their computers, gaming consoles, and home entertainment systems running during power interruptions.

One of the standout features is the automatic voltage regulation (AVR), which helps maintain a stable power supply, preventing potential damage from fluctuations. The mini tower design with a 6-foot power cord makes it easy to place in various locations without taking up too much space, which is a plus for smaller setups.

There are some limitations to be aware of. The UPS has a maximum load recommendation of 80% of its rated capacity for optimal performance, which may restrict users who want to connect multiple high-powered devices. Additionally, while the lead-acid battery composition is standard, it may not be as efficient or long-lasting as some newer battery technologies available on the market.

The Vertiv Liebert PSI5 Lithium Ion UPS is a robust power backup solution ideal for both home and small business environments. With a power capacity of 1500VA/1350W, it’s powerful enough to support a range of devices during power outages. Its lithium-ion battery stands out, offering twice the lifespan of traditional VRLA batteries, which translates to savings over time since it can endure up to 10 times more charge/discharge cycles.

The UPS provides up to 8 minutes of runtime at full load and 18 minutes at half load, which should be sufficient for most users to safely shut down their equipment or switch to a generator if needed. Notably, the unit includes three programmable outlets, adding a layer of flexibility for prioritizing critical devices. The form factor is versatile, designed to fit both rack and tower setups, and includes a rotating LCD display for easy monitoring. This model also comes with an SNMP/Webcard for remote management and free Power Insight management software, which can be a significant advantage for users needing to manage their UPS remotely.

However, at 41.8 pounds, it is relatively heavy, which might pose some challenges during installation. The Vertiv Liebert PSI5 seems to be a reliable and cost-effective UPS with advanced features suitable for a variety of settings.

The Liebert GXT4 UPS, though now obsolete and replaced by the GXT5 model, still offers significant features for robust power protection. It provides a high power capacity of 6000VA/4800W, which is suitable for critical systems requiring consistent power. Its online double-conversion technology ensures clean, stable power by continuously conditioning the power supply, greatly extending battery life.

The integrated communications card allows for remote monitoring and management, adding a layer of convenience for users needing oversight of multiple systems. The UPS also features a seamless transfer to battery power, ensuring uninterrupted operation during power outages. However, the battery runtime at full load is up to 5 minutes, which might be inadequate for some users without additional external battery cabinets for extended periods.

The unit is versatile, with both rack-mount and tower form factors, but its size and weight might be cumbersome for smaller setups. Included accessories, such as the rack-mounting rail kit and various cables, add value and ease installation. This product is best suited for environments requiring high capacity and reliable power protection, such as data centers or critical network infrastructures. However, users should consider the updated GXT5 model for more current features and potential improvements.
