The Vertiv Liebert PSI5 Lithium Ion UPS is a solid choice if you need reliable backup power for your computer or networking equipment. It offers 1500VA / 1350W power capacity, which is suitable for small to medium setups. The lithium-ion battery lasts much longer than traditional batteries—up to 10 times more cycles—meaning this UPS will likely serve you well for years and save money over time. It provides about 8 minutes of runtime at full load and around 18 minutes at half load, enough to safely shut down your devices during power outages.
The UPS includes three programmable outlets, allowing you to prioritize which devices get power during an outage, and has a rotating LCD display that makes it easy to check status. Its form factor is 2U rack/tower, making it flexible for different setups. The built-in Automatic Voltage Regulation (AVR) helps protect connected equipment from voltage spikes or drops, and it also features surge protection for added safety. Another strong point is the SNMP/Webcard option for remote management and free Power Insight software, useful if you want to monitor your UPS remotely.
It weighs 42 pounds and measures about 16 inches wide and deep but only 3.4 inches tall, so it’s not the lightest or smallest unit, which may be a consideration if space or portability is important. Its price can be higher than some traditional UPS models, largely because of the lithium-ion battery and advanced features. If you want a UPS that combines longer battery life, decent runtime, and good management tools—and don’t mind a bit of extra weight—this model is a dependable option.
The Vertiv Liebert GXT5 UPS is a robust and reliable choice for users looking for a dependable uninterruptible power supply. With a power capacity of 2000VA/1800W, it is well-suited for powering essential equipment during outages. One of its standout features is the online double conversion technology, which ensures consistent power quality by continuously converting incoming power to DC and then back to AC. This makes it ideal for environments where power reliability is critical.
The UPS is designed in a versatile 2U rack/tower format, granting flexibility in installation and saving valuable space. Its energy efficiency is boosted by the Energy Star 2.0 certification, which means it operates efficiently even in eco-mode, making it a cost-effective solution over time. Additionally, the unit includes automatic voltage regulation (AVR) to protect against voltage fluctuations, and the sine wave output provides clean power suitable for sensitive electronics. The updated firmware addresses previous fan noise issues, enhancing user experience.
However, at 58.7 pounds, the unit is relatively heavy, which could pose challenges during installation. The sealed lead-acid battery, while reliable, may require eventual replacement, which could be a downside compared to newer battery technologies like lithium-ion. The device's color graphic display with gravity sensing is a user-friendly feature, providing easy access to information and settings. The four programmable output receptacles offer versatile options for managing connected devices and optimizing battery usage.
In summary, the Vertiv Liebert GXT5 is a powerful UPS for those needing solid protection and performance for their computing devices, particularly in settings where power stability is crucial. Despite its weight and potential battery maintenance needs, its advanced features and energy efficiency make it a strong contender in the UPS market.
