APC by Schneider Electric SYH6K6RMI vs Vertiv GXT5-6000MVRT4UXLN: Specification Comparison
Both products are rack-mountable, hardwired-input, 6 kVA-class uninterruptible power supplies aimed at data-center and critical-infrastructure installations. The APC Symmetra RM SYH6K6RMI is a modular, scalable architecture UPS with an N+1 redundancy design, while the Vertiv GXT5-6000MVRT4UXLN is an online double-conversion unit with a flexible rack/tower form factor and a factory-installed SNMP management card. Both target the same buyer segment—IT managers and integrators specifying mid-range runtime protection for server rooms and network closets.

How do the two units compare on power capacity, efficiency, and runtime?
The SYH6K6RMI is rated at 6 kVA / 4,200 W, giving a power factor of 0.70. At full load (4,200 W) APC specifies a typical runtime of 12.7 minutes; at half load (2,100 W) that extends to 30.3 minutes. No efficiency figure is provided in the supplied specifications.
The GXT5-6000MVRT4UXLN is rated at 6,000 VA / 6,000 W, reflecting a unity (1.0) power factor. Vertiv specifies up to 98% efficiency in Active ECO Mode and up to 95% in online double-conversion mode. No runtime figures at full or half load are provided in the supplied specifications.
For load-sensitive deployments, the Vertiv's unity power factor means the full 6,000 W is usable, whereas the APC's 0.70 power factor caps usable watts at 4,200 W on the same 6 kVA rating. Buyers who need confirmed runtime numbers before procurement will find that data available only for the APC in these specifications.
What are the input voltage, output connections, and wiring requirements for each unit?
The SYH6K6RMI accepts input via a Hard Wire 3-wire connection. Its output consists of eight IEC 320 C13 receptacles and two IEC 320 C19 receptacles—ten total outlets, all IEC 60320 standard. Input voltage range is not stated in the supplied specifications.
The GXT5-6000MVRT4UXLN also uses hardwired input and output. Input voltage is typically 208 VAC with a range of 176–280 VAC. Output is user-configurable between 208 VAC and 120 VAC (120/208 VAC dual-voltage). Specific outlet count and receptacle types are not stated in the supplied specifications. Optional Power Output Distribution (POD) modules are noted as available.
The APC unit lists discrete IEC outlet counts, which is useful for direct-attach load planning. The Vertiv's user-configurable dual-voltage output (208 V or 120 V) adds flexibility for mixed-voltage rack environments, but buyers requiring a specific outlet count and type must consult the Vertiv datasheet or request a POD configuration quote.
How do the management interfaces, certifications, and form-factor features differ?
The SYH6K6RMI provides a DB-9 RS-232 serial port and an RJ-45 10Base-T Ethernet port supporting web, SNMP, and Telnet management. Emergency Power Off (EPO) is explicitly listed. The unit's operating humidity range is 0–95% (non-condensing not specified); operating temperature is 0–40 °C. No energy certifications are listed in the supplied specifications.
The GXT5-6000MVRT4UXLN ships with a factory pre-installed Vertiv RDU101 SNMP/Web card, plus USB, RS-485, RS-232, a terminal block, and an external battery connector—six interface options in total. A full-color graphic LCD with gravity-sensing orientation is included for local status. Certifications listed include ENERGY STAR 2.0, UL 1778, c-UL, RoHS2, and REACH. EPO capability is not stated in the supplied specifications.
For environments requiring documented energy or safety compliance (government, healthcare, regulated data centers), the Vertiv carries a broader listed certification set. The APC's explicit EPO listing is a concrete advantage where EPO is a code or insurance requirement. The Vertiv's gravity-sensing LCD eases installation in either rack or tower orientation without additional configuration.
Which should you choose: the SYH6K6RMI or the GXT5-6000MVRT4UXLN?
Our take: The GXT5-6000MVRT4UXLN is the stronger choice when maximum usable wattage, efficiency, and out-of-the-box management card coverage are the primary drivers. Its unity power factor delivers the full 6,000 W versus the SYH6K6RMI's 4,200 W ceiling—a 43% higher usable load on the same VA rating—and its up-to-98% ECO-mode efficiency reduces operating costs over the product's life. Six interface options and a factory-installed SNMP/Web card lower deployment labor compared to the APC's two-port management approach. Conversely, the SYH6K6RMI provides concrete runtime data (12.7 min full load, 30.3 min half load) and an explicit EPO listing absent from the Vertiv's supplied specs, which matters when EPO is a code requirement or when runtime guarantees must appear in a bid document. Choose the APC for EPO-mandated or runtime-specified legacy refresh projects; choose the Vertiv for new builds requiring high efficiency, dual-voltage output flexibility, and comprehensive certifications.

Frequently Asked Questions
Which should you choose: the SYH6K6RMI or the GXT5-6000MVRT4UXLN?
The GXT5-6000MVRT4UXLN is the stronger choice when maximum usable wattage, efficiency, and out-of-the-box management card coverage are the primary drivers. Its unity power factor delivers the full 6,000 W versus the SYH6K6RMI's 4,200 W ceiling—a 43% higher usable load on the same VA rating—and its up-to-98% ECO-mode efficiency reduces operating costs over the product's life. Six interface options and a factory-installed SNMP/Web card lower deployment labor compared to the APC's two-port management approach. Conversely, the SYH6K6RMI provides concrete runtime data (12.7 min full load, 30.3 min half load) and an explicit EPO listing absent from the Vertiv's supplied specs, which matters when EPO is a code requirement or when runtime guarantees must appear in a bid document. Choose the APC for EPO-mandated or runtime-specified legacy refresh projects; choose the Vertiv for new builds requiring high efficiency, dual-voltage output flexibility, and comprehensive certifications.
Which unit supports more connected loads—the SYH6K6RMI or the GXT5-6000MVRT4UXLN?
Based on supplied specifications, only the SYH6K6RMI lists specific outlet counts: eight IEC 320 C13 and two IEC 320 C19 receptacles for ten total outlets. The GXT5-6000MVRT4UXLN's outlet count and types are not stated in the provided specifications; optional POD modules are noted as available, which may expand capacity. Buyers should consult the Vertiv datasheet or a POD configuration sheet before finalizing load planning.
Does either UPS carry ENERGY STAR certification?
Yes—the Vertiv GXT5-6000MVRT4UXLN is listed as ENERGY STAR 2.0 certified. The APC SYH6K6RMI's supplied specifications do not include any energy-certification listing. If ENERGY STAR compliance is required for procurement, purchasing, or utility-rebate purposes, the Vertiv is the documented choice based on available spec data.
Which unit is better suited for a site that requires Emergency Power Off (EPO) capability?
The APC SYH6K6RMI explicitly lists Emergency Power Off (EPO) as a feature in its supplied specifications. The Vertiv GXT5-6000MVRT4UXLN's supplied specifications do not mention EPO. If EPO is mandated by the National Electrical Code, a local authority having jurisdiction, or an insurance underwriter, the SYH6K6RMI has a confirmed spec entry to cite; the Vertiv would require datasheet or factory confirmation before inclusion in an EPO-compliant design.
