- Protect critical rack equipment with 900 W of UPS output
Maintain uptime for critical rack equipment with a UPS designed for tight spaces and demanding workloads. The Vertiv Liebert PSI5 UPS 1000 combines 900 W of output with a 1U rack-mount footprint, making it a practical fit for branch offices, network closets, and distributed IT racks where every unit of space matters.
Built around 120 VAC operation, this model is sized for standard North American deployments and helps protect servers, switches, and storage from short power interruptions and unstable utility conditions. Its compact chassis supports cleaner rack planning without forcing teams to sacrifice protection for density.
For procurement teams and infrastructure owners, the value is straightforward: preserve uptime, reduce disruption, and keep essential systems running long enough for graceful shutdown or generator transfer. Compared with lower-capacity alternatives, the PSI5 1000 gives you more headroom for connected equipment while staying in a space-efficient 1U form factor. That balance matters when the rack is full and downtime is expensive.
Ideal For
- Protecting branch office servers during short power outages
- Backing up network switches and firewalls in a rack closet
- Supporting storage and edge compute in space-constrained cabinets
- Providing orderly shutdown time for critical infrastructure
