Keep essential infrastructure online with the Vertiv PSI5 2200VA 1920W rack-tower UPS. Built for 120 VAC environments, it delivers 2,200 VA and 1,920 W of capacity for servers, switches, and attached storage that cannot tolerate even short interruptions. The 2U rack-tower design makes it practical for dense edge deployments where space is limited and uptime is not optional. This model sits in the right part of the power curve for teams that need more than a small office UPS, but do not want the cost, footprint, or complexity of a larger system. Its 1,920 W output rating gives you meaningful load support for modern IT equipment, while the rack-tower chassis allows flexible installation in either rack or tower environments. For infrastructure teams standardizing on dependable power protection, the PSI5 is a strong fit for branch offices, network closets, and distributed compute rooms. It is sized to protect critical loads without excess overhead, which helps justify the investment when uptime, rack density, and budget discipline all matter.
