How do the two UPS units compare on usable power output, runtime, and efficiency?
The APC SYH6K6RMI is rated at 6,000 VA / 4,200 W, giving a power factor of approximately 0.70. At full load (4,200 W) it provides 12.7 minutes of runtime; at half load (2,100 W) runtime extends to 30.3 minutes, per APC's published specs. Battery chemistry is maintenance-free sealed lead-acid with suspended electrolyte. The replacement battery cartridge is the APC SYBT2.
The Vertiv GXT5-6KL630RT5UXLN is rated at 4,900 VA / 4,600 W, yielding a power factor of approximately 0.94. Runtime figures at full or half load are not provided in the supplied specifications. Efficiency is stated as up to 98% in Active ECO Mode and up to 95% in on-line double-conversion mode. Battery type and replacement cartridge designation are not specified in the provided data.
On usable watt output the Vertiv delivers meaningfully more real power (4,600 W vs 4,200 W) despite a slightly lower VA rating, owing to its higher power factor. The APC provides documented runtime figures; the Vertiv does not in the provided specs. The Vertiv's efficiency claim (up to 98% ECO / 95% online) is documented; no efficiency figure is provided for the APC.
Which unit offers broader connectivity, outlet configurations, and remote management capabilities?
The APC SYH6K6RMI provides eight IEC 320 C13 and two IEC 320 C19 output receptacles — a total of ten outlets. Input connection is hard-wire 3-wire. Management interfaces include DB-9 RS-232 and RJ-45 10Base-T Ethernet for web, SNMP, and Telnet management. Emergency Power Off (EPO) is supported.
The Vertiv GXT5-6KL630RT5UXLN outputs via two L6-20R and two L6-30R receptacles — four outlets total. Input is an L6-30P plug. Management is handled through a factory pre-installed Vertiv RDU101 SNMP/web card, plus USB, RS-485, RS-232, a terminal block, and an external battery connector. A full-color graphic LCD with gravity-sensing orientation is built in. SNMP and web management are enabled out of the box. No EPO status is noted in the provided specs.
The APC offers significantly more outlet positions (10 vs 4), uses IEC C13/C19 receptacles common in rack PDU environments, and includes EPO. The Vertiv ships with its SNMP/web card pre-installed and adds USB and RS-485 alongside RS-232, broadening out-of-band management options. The Vertiv's L6-30R/L6-20R outlets suit North American 208 V installations; the APC's IEC outlets suit international or globally standardized data centers.
How do the two units compare on physical footprint, weight, and environmental operating range?
The APC SYH6K6RMI dimensions are 482.6 mm W × 730.3 mm D × 355.6 mm H (approximately 19.0 × 28.8 × 14.0 in). Weight is not provided in the supplied specifications. Operating temperature range is 0–40 °C; storage temperature is −15 to 45 °C. Operating relative humidity is 0–95%; storage relative humidity is 0–95%.
The Vertiv GXT5-6KL630RT5UXLN measures 16.9 in W × 23.6 in D × 8.5 in H (approximately 429 mm × 599 mm × 216 mm) and weighs 149.1 lb (67.6 kg). Operating temperature is 0–40 °C (matching the APC). No storage temperature or humidity range is provided in the supplied specifications.
The Vertiv is shallower (23.6 in vs 28.8 in) and shorter (8.5 in / ~5U vs ~14U for the APC), which may be advantageous in space-constrained racks. The APC's depth of 730 mm may require a deeper rack or cable-management accommodation. The APC documents both storage temperature and humidity; the Vertiv does not in the provided data. Weight is documented only for the Vertiv. Certifications for the Vertiv include ENERGY STAR 2.0, UL 1778, c-UL, RoHS2, and REACH; no certifications are listed for the APC in the provided specs.
Which should you choose: the SYH6K6RMI or the GXT5-6KL630RT5UXLN?
Our take: The GXT5-6KL630RT5UXLN is the stronger choice when maximizing real-power delivery, management depth, and efficiency in a North American 208 V rack environment. It delivers 4,600 W of usable output versus the SYH6K6RMI's 4,200 W — a 9.5% advantage — despite a lower VA rating, driven by its 0.94 power factor. Its documented efficiency of up to 95% on-line (98% ECO) reduces operating costs over time; no equivalent figure is provided for the APC. The Vertiv also ships with a pre-installed SNMP/web card and adds USB and RS-485 interfaces, whereas the APC requires an add-on for equivalent management depth. Conversely, the SYH6K6RMI suits internationally standardized data centers via its IEC C13/C19 outlets, documents runtime (12.7 min at full load), supports EPO, and provides humidity and storage-temperature specs absent from the Vertiv's data sheet. Buyers prioritizing outlet count (10 vs 4) or IEC receptacles should weigh the APC accordingly.

Which UPS delivers more usable power — the SYH6K6RMI or the GXT5-6KL630RT5UXLN?
The Vertiv GXT5-6KL630RT5UXLN delivers more real power: 4,600 W versus 4,200 W for the APC SYH6K6RMI. Although the APC carries a higher VA rating (6,000 VA vs 4,900 VA), the Vertiv's power factor of approximately 0.94 versus the APC's 0.70 means it converts more of its VA capacity into usable watts for connected equipment.
Is the SYH6K6RMI or the GXT5-6KL630RT5UXLN better for environments that require documented runtime?
The APC SYH6K6RMI is the only unit with runtime figures provided in the supplied specifications: 12.7 minutes at full load (4,200 W) and 30.3 minutes at half load (2,100 W). The Vertiv GXT5-6KL630RT5UXLN does not include runtime data in the specifications provided, so a direct comparison cannot be made from the available data.
Which unit is easier to monitor and manage remotely out of the box?
The Vertiv GXT5-6KL630RT5UXLN ships with a factory pre-installed RDU101 SNMP/web card, enabling SNMP and web management without an additional purchase. It also includes USB, RS-485, RS-232, and a terminal block. The APC SYH6K6RMI provides RJ-45 10Base-T Ethernet for web/SNMP/Telnet and DB-9 RS-232, but the specifications do not confirm whether a management card is included or an optional add-on.
