Power Supply Unit Fantec NT-MR550W 550W 2U Metallic

The Fantec NT-MR550W 550W 2U Metallic is a server-grade power supply unit designed for compact rack environments. It delivers up to 550 watts of continuous power in a 2U form factor and uses a metallic enclosure for improved heat dissipation and mechanical stability. The unit includes an integrated 40 mm cooling fan and accepts a wide AC input range of 110–240 V, making it compatible with diverse data center and IT room power conditions. With an MTBF rated at 100,000 hours and compact dimensions (84 mm × 77 mm × 230 mm), the PSU is intended for reliable, long-term operation in rack-mounted systems.

Advantages

The metallic housing supports effective thermal conduction and mechanical protection while keeping the unit lightweight and compact for 2U installations. Active cooling with a 4 cm fan helps maintain stable operating temperatures under load. Wide AC input compatibility simplifies installation across regions with different mains voltages. The high MTBF indicates low failure rates and suitability for continuous server operation.

Suitable for

• Rack-mounted servers and small data center appliances with 2U space constraints
• Network equipment and storage systems requiring a 550W single-output PSU
• Systems operated in environments with variable mains voltage (110–240 V)

Key specifications

• Output power: 550 W continuous
• Form factor: 2U, metallic enclosure
• Cooling: 40 mm (4 cm) active fan
• Input voltage: 110–240 V AC
• Mean time between failures (MTBF): 100,000 hours
• Dimensions (W × D × H): 84 mm × 77 mm × 230 mm

How to use

Install the PSU into the appropriate 2U bay of the server or rack chassis following the chassis manufacturer’s mounting instructions. Connect the AC mains input to a properly rated supply within the 110–240 V range and attach the unit’s DC output connector(s) to the server power input harness as specified by the system documentation. Ensure adequate airflow around the unit and avoid obstructing the 40 mm fan intake and exhaust. Perform initial power-on tests with monitoring of system voltages and temperatures to confirm stable operation.

Usage recommendations

For reliable long-term operation, maintain ambient temperature and ventilation within the server room specifications, use surge protection or conditioned power where needed, and schedule periodic inspections for dust buildup around the fan and ventilation openings.
