Vertiv PSA6-1000LVT vs Vertiv RDU101: Specification Comparison
Both products are 1000VA uninterruptible power supplies operating on 120V AC, but they represent fundamentally different UPS topologies and form factors. The PSA6-1000LVT is a desktop line-interactive UPS rated at 625W, while the GXT5-1000LVRT2UXLN is an online double-conversion rack/tower unit rated at 1000W. Buyers cross-shopping at the 1000VA tier will find these occupy opposite ends of the desktop-vs-rack and line-interactive-vs-online-conversion spectrum, making the comparison valid for a buyer deciding which tier of protection and deployment model fits their environment.

Which UPS delivers more usable power and what level of power conditioning does each provide?
The PSA6-1000LVT is a line-interactive desktop UPS rated at 1000VA / 625W, yielding a power factor of 0.625. Line-interactive topology uses AVR (automatic voltage regulation) to handle minor voltage fluctuations without switching to battery, but transfers to battery for more severe events. Output voltage is 120 VAC; no configurable output range is specified in the provided data.
The GXT5-1000LVRT2UXLN is an online double-conversion UPS rated at 1000VA / 1000W, yielding a power factor of 1.0. Double-conversion topology continuously regenerates output power, providing zero-transfer-time switching and complete isolation from all input power anomalies. Output is user-configurable at 110/115/120/125 VAC ±3%, and the unit accepts an input range of 60–150V. Efficiency is rated up to 98% in Active ECO Mode and up to 95% in on-line mode.
At identical VA ratings, the GXT5 delivers 375W more usable power (1000W vs 625W) and provides a higher grade of power conditioning. The PSA6-1000LVT's output wattage and efficiency figures are not stated in the provided specifications.
How do the form factor, installation footprint, and management interfaces compare?
The PSA6-1000LVT is a desktop unit measuring 11.34 in H × 4.72 in W × 11.42 in D and weighing 18.7 lbs. It is designed for placement on a desk or floor. No rack-mount option is referenced in the provided specifications. Management interfaces are not specified in the provided data.
The GXT5-1000LVRT2UXLN supports both rack-mount (2U) and tower orientations, measuring 3.4 in H × 16.9 in W × 15.7 in D and weighing 37 lbs. Management interfaces include USB, RS485, RS232, a terminal block, and an external battery connector. SNMP and web management are enabled via the optional Vertiv Liebert IntelliSlot RDU120 communications card. A colored graphic LCD with gravity-sensing orientation provides local status and configuration. The input wiring is NEMA 5-15P; output is six NEMA 5-15R receptacles, four of which are individually programmable.
The PSA6-1000LVT is substantially lighter and more compact, suiting a single-workstation or small-office desktop context. The GXT5-1000LVRT2UXLN's rack/tower flexibility and rich interface options suit IT closet or data-center rack deployments where remote monitoring and outlet-level control are required.
What certifications, environmental ratings, and warranty terms apply to each unit?
The PSA6-1000LVT carries a 3-year full-unit warranty including battery with advanced replacement. No operating temperature range, certifications, or compliance listings are provided in the supplied specifications.
The GXT5-1000LVRT2UXLN is ENERGY STAR 2.0 certified and listed to UL 1778 4th edition and CSA 22.2 No. 107.1. It also carries WEEE, RoHS2, and REACH compliance. Operating temperature is rated +32 to +104 °F (0 to 40 °C). Warranty terms are not stated in the provided specifications.
The PSA6-1000LVT offers a clearly documented and differentiated warranty—three years covering both unit and battery with advanced replacement—which is a meaningful buyer benefit that is absent from the GXT5's provided data. The GXT5 leads on formal safety and environmental certifications. Neither product's provided specifications cover both warranty and certifications simultaneously, so buyers should verify the missing term for their preferred model directly with Vertiv.
Which should you choose: the PSA6-1000LVT or the RDU101?
Our take: The PSA6-1000LVT is the stronger choice when a buyer needs a compact, lightweight desktop UPS for a single workstation or small-office environment and values a clearly documented 3-year battery-inclusive warranty with advanced replacement. The GXT5-1000LVRT2UXLN is the stronger choice for IT infrastructure deployments demanding maximum power conditioning: it delivers 1000W of usable power versus the PSA6's 625W (a 60% increase), uses online double-conversion topology for zero-transfer-time protection against all input anomalies versus line-interactive, and offers four individually programmable output receptacles plus USB/RS485/RS232/SNMP-ready management versus no management interfaces documented for the PSA6. The GXT5 also weighs 37 lbs versus 18.7 lbs and fits a 2U rack or tower. Buyers running rack-mounted servers, network equipment, or storage arrays should select the GXT5; buyers powering a desktop workstation or small peripheral cluster should evaluate the PSA6-1000LVT.

Frequently Asked Questions
Which should you choose: the PSA6-1000LVT or the RDU101?
The PSA6-1000LVT is the stronger choice when a buyer needs a compact, lightweight desktop UPS for a single workstation or small-office environment and values a clearly documented 3-year battery-inclusive warranty with advanced replacement. The GXT5-1000LVRT2UXLN is the stronger choice for IT infrastructure deployments demanding maximum power conditioning: it delivers 1000W of usable power versus the PSA6's 625W (a 60% increase), uses online double-conversion topology for zero-transfer-time protection against all input anomalies versus line-interactive, and offers four individually programmable output receptacles plus USB/RS485/RS232/SNMP-ready management versus no management interfaces documented for the PSA6. The GXT5 also weighs 37 lbs versus 18.7 lbs and fits a 2U rack or tower. Buyers running rack-mounted servers, network equipment, or storage arrays should select the GXT5; buyers powering a desktop workstation or small peripheral cluster should evaluate the PSA6-1000LVT.
Is the PSA6-1000LVT or the GXT5-1000LVRT2UXLN better for powering a server rack?
The GXT5-1000LVRT2UXLN is better suited for a server rack. It supports rack-mount installation (2U), delivers 1000W of output power via online double-conversion topology, and provides USB, RS485, RS232, and optional SNMP management for remote monitoring. The PSA6-1000LVT is a desktop unit rated at 625W with no rack-mount option or management interfaces documented in its specifications.
Which unit provides better protection against power anomalies—line sags, surges, and outright failures?
The GXT5-1000LVRT2UXLN provides a higher level of protection. Its online double-conversion topology continuously regenerates output power, meaning the connected load is always running from a clean, conditioned sine wave with zero transfer time on switchover. The PSA6-1000LVT uses line-interactive topology, which handles minor voltage variations via AVR but does require a brief transfer to battery for more severe events. For sensitive equipment, double-conversion is the more robust choice.
Which UPS has the better warranty, and does either include battery coverage?
Based on the provided specifications, the PSA6-1000LVT has a documented 3-year full-unit warranty that explicitly includes battery coverage and advanced replacement—a meaningful differentiator. Warranty terms for the GXT5-1000LVRT2UXLN are not included in the specifications provided here. Buyers should confirm the GXT5 warranty directly with Vertiv before making a decision based on coverage terms.
