How do the SYH6K6RMT-TF3 and GXT5-6KL630RT5UXLN compare on power delivery, output flexibility, and efficiency?
The APC SYH6K6RMT-TF3 is rated at 6,000 VA / 4,200 W, giving it a power factor of 0.70. Its output connections are 4× NEMA L5-20R and 2× NEMA L6-20R, covering both 120 V and 208 V receptacle types. Input frequency is specified at 60 Hz. No efficiency rating is provided in the supplied specifications.
The Vertiv GXT5-6KL630RT5UXLN is rated at 4,900 VA / 4,600 W, yielding a notably higher power factor of approximately 0.94. Output voltage is user-configurable across 200 / 208 / 220 / 230 / 240 VAC, providing greater flexibility for mixed or international equipment. Input accepts 175–280 VAC (typical 208 VAC) via an L6-30P plug. Efficiency is specified at up to 98% in Active ECO Mode and up to 95% in online double-conversion mode. Output receptacles are 2× L6-20R and 2× L6-30R, covering 208 V loads only. The Vertiv's topology is explicitly stated as online double-conversion; the APC's topology is not specified in the provided data.
Which unit offers more management and connectivity options for IT and facilities teams?
The APC SYH6K6RMT-TF3 provides a DB-9 RS-232 serial port and an RJ-45 interface. Emergency Power Off (EPO) and audible alarms are confirmed. No SNMP card, web interface, USB port, or network management protocol is listed in the supplied specifications.
The Vertiv GXT5-6KL630RT5UXLN ships with a factory pre-installed Vertiv RDU101 SNMP/Webcard, enabling SNMP and web-based remote monitoring out of the box. Additional interfaces include USB, RS-485, RS-232, a terminal block, and an external battery connector. SNMP and web management are enabled by default; serial is available for out-of-band management. The unit also features a full-color graphic LCD control panel with gravity-sensing orientation for both rack and tower installation. EPO capability and audible alarm status are not stated in the provided Vertiv specifications.
How do the two units differ in physical size, weight, battery characteristics, and environmental ratings?
The APC SYH6K6RMT-TF3 weighs 176.8 kg (approximately 390 lb). Physical dimensions are not provided in the supplied specifications. Battery technology is Sealed Lead Acid (VRLA) with a stated recharge time of 3 hours and confirmed hot-swap capability. Operating temperature range is 0–40 °C; storage is –15 to 45 °C. Operating and storage relative humidity are both rated 0–95%. Certifications listed are CSA, FCC Part 15 Class A, and UL 1778. Cable length is 1.83 m.
The Vertiv GXT5-6KL630RT5UXLN weighs 149.1 lb (approximately 67.6 kg)—substantially lighter than the APC unit. Rack dimensions are 8.5 in H × 16.9 in W × 23.6 in D. Operating temperature is 0–40 °C (32–104 °F). Battery technology, recharge time, and hot-swap status are not specified in the provided data. Certifications include ENERGY STAR 2.0, UL 1778, c-UL, RoHS2, and REACH. The flexible rack/tower form factor is explicitly noted. No humidity rating is provided in the supplied specifications.
Which should you choose: the SYH6K6RMT-TF3 or the GXT5-6KL630RT5UXLN?
Our take: The GXT5-6KL630RT5UXLN is the stronger choice when management depth, energy efficiency, and physical weight are the primary concerns, while the SYH6K6RMT-TF3 has an advantage if mixed 120 V / 208 V output receptacles or hot-swap battery serviceability are required. On power delivery, the Vertiv's 4,600 W real-power output and ~0.94 power factor outperform the APC's 4,200 W and 0.70 power factor despite the APC's higher VA rating. The Vertiv specifies up to 98% efficiency in ECO mode versus no stated efficiency for the APC. On weight, the Vertiv at 149.1 lb is dramatically lighter than the APC at 176.8 kg (~390 lb), a significant factor for rack-density and floor-load planning. The APC's confirmed hot-swap VRLA batteries and dual-voltage output receptacles (L5-20R + L6-20R) suit environments with legacy 120 V loads, while the Vertiv's factory SNMP card and configurable output voltage favor modern, network-managed 208 V data center deployments.

Frequently Asked Questions
Which should you choose: the SYH6K6RMT-TF3 or the GXT5-6KL630RT5UXLN?
The GXT5-6KL630RT5UXLN is the stronger choice when management depth, energy efficiency, and physical weight are the primary concerns, while the SYH6K6RMT-TF3 has an advantage if mixed 120 V / 208 V output receptacles or hot-swap battery serviceability are required. On power delivery, the Vertiv's 4,600 W real-power output and ~0.94 power factor outperform the APC's 4,200 W and 0.70 power factor despite the APC's higher VA rating. The Vertiv specifies up to 98% efficiency in ECO mode versus no stated efficiency for the APC. On weight, the Vertiv at 149.1 lb is dramatically lighter than the APC at 176.8 kg (~390 lb), a significant factor for rack-density and floor-load planning. The APC's confirmed hot-swap VRLA batteries and dual-voltage output receptacles (L5-20R + L6-20R) suit environments with legacy 120 V loads, while the Vertiv's factory SNMP card and configurable output voltage favor modern, network-managed 208 V data center deployments.
Is the SYH6K6RMT-TF3 or GXT5-6KL630RT5UXLN better for a mixed 120 V and 208 V server environment?
Based on the provided specifications, the SYH6K6RMT-TF3 is the only unit here that offers both 120 V (NEMA L5-20R) and 208 V (NEMA L6-20R) output receptacles, making it more suitable for environments mixing legacy 120 V gear with 208 V equipment. The GXT5-6KL630RT5UXLN's output receptacles (L6-20R and L6-30R) are 208 V only, though its output voltage is user-configurable from 200 to 240 VAC.
Which UPS can I monitor remotely without buying an add-on network card?
The Vertiv GXT5-6KL630RT5UXLN ships with a factory pre-installed RDU101 SNMP/Webcard, enabling SNMP and web-based management out of the box at no additional cost. The APC SYH6K6RMT-TF3's provided specifications list only DB-9 RS-232 and RJ-45 interfaces; no SNMP card or web management capability is mentioned in the supplied data.
Can the batteries be replaced without powering down connected equipment?
The APC SYH6K6RMT-TF3 explicitly lists hot-swap battery capability in its specifications, allowing battery replacement under load without shutting down connected devices. The Vertiv GXT5-6KL630RT5UXLN's provided specifications do not state whether battery replacement is hot-swap capable; that information is absent from the supplied data and should be confirmed with Vertiv documentation before purchasing.
