Vertiv GXT3-1000MT120 1000VA 900W Mini-Tower UPS
Overview
The Vertiv Liebert GXT3-1000MT120 is a 1000 VA / 900W mini-tower uninterruptible power supply designed for 120V AC environments. It provides battery backup and power conditioning for connected equipment — making it a practical fit for surveillance servers, NVRs, network switches, and edge computing nodes where an unexpected power interruption means lost footage or dropped connections. The mini-tower form factor keeps it deployable at the rack's base or on a desktop shelf without requiring rail space.
Key Features
- 1000 VA / 900W Power Capacity: The 900W real-power rating (0.9 power factor) means you can load this unit near its VA ceiling without clipping — unlike lower power-factor UPS units that derate significantly. Size your connected load against the 900W figure, not the 1000 VA headline.
- 120V AC Input: Wired for standard North American single-phase circuits. No step-down transformer or special outlet required — plugs directly into a standard 15A or 20A wall receptacle depending on configuration.
- Mini-Tower Form Factor: The external mini-tower chassis keeps the unit off the floor and away from rack infrastructure. Useful in wiring closets, server alcoves, or under-desk NVR installs where a rackmount 1U/2U unit would be impractical or where rack space is already committed.
- External Power Device Classification: Classified as an external power device, meaning it operates independently of the host equipment's internal power supply — provides protection upstream of your gear, not integrated within it.
Integration & Compatibility
The GXT3-1000MT120 (often searched as GXT3 1000MT120) is designed for 120V AC infrastructure. It suits environments running network video recorders, PoE switches, and edge servers that require clean, conditioned power. For deployments running multiple IP cameras and associated network switches, pairing a dedicated UPS per power zone is a sound approach — a single UPS protecting both the NVR and its upstream switch eliminates the most common single-point failure in a surveillance power architecture. For broader power protection planning across larger installations, consider whether a single 1000 VA unit covers your full connected load or whether parallel units per zone are warranted. Consult the Vertiv power protection catalog for higher-capacity models if your load exceeds 900W.
Frequently Asked Questions
Q: What is the real power output of the GXT3-1000MT120?
A: The GXT3-1000MT120 delivers 900 watts of real power at a 0.9 power factor. When sizing connected equipment, use 900W as your ceiling — not the 1000 VA apparent power figure.
Q: What input voltage does the GXT3-1000MT120 require?
A: It requires 120V AC input, standard for North American single-phase circuits. No transformer or voltage converter is needed on a standard US electrical circuit.
Q: Is the GXT3-1000MT120 rack-mountable?
A: It is configured as an external mini-tower unit, not a rackmount form factor. It is intended for desktop or floor placement adjacent to rack infrastructure, not for installation in a standard 19-inch equipment rack.
Q: What types of equipment is the GXT3-1000MT120 suitable for protecting?
A: Its 1000 VA / 900W capacity and 120V input make it suitable for NVRs, PoE network switches, edge servers, and workstations in surveillance or IT closet environments running on standard North American power.
The GXT3-1000MT120 sits at a practical capacity point for small-to-mid surveillance closets — 900W of real power output at 0.9 power factor means you are not leaving headroom on the table the way lower-factor units do. For a wiring closet running a 16-channel NVR, a managed PoE switch, and a router, this unit covers the load without requiring a step up to the next capacity tier.
Technical Highlights:
- 900W Real Power (0.9 PF): A 0.9 power factor is meaningfully better than the 0.6–0.7 PF common on entry-level UPS units — you get 900W usable against the 1000 VA rating, not 600–700W.
- 1000 VA Capacity: Sufficient to carry a typical surveillance edge stack — NVR, PoE switch, and access control panel — through a short outage or a controlled shutdown sequence.
- 120V AC Input: Plug-and-play on any standard North American 15A or 20A circuit. No electrician work, no special outlet — relevant when deploying in leased space or retrofitting existing infrastructure.
Deployment Considerations:
- Confirm your connected load does not exceed 900W before commissioning — add up NVR idle draw, switch PoE budget, and any additional devices on the same circuit.
- The mini-tower form factor is not rack-mountable as shipped. If your installation is a fully racked environment, verify whether a rack-mount kit or a different GXT3 variant is appropriate before purchasing.
Best fit for a surveillance wiring closet or edge IT alcove running a single NVR stack on North American 120V power, where desktop placement is acceptable and load stays under 900W.
