Power Supply Supermicro MCP-240-51502-0N 240W 1U

The Supermicro MCP-240-51502-0N 240W 1U internal power supply is a compact, server-grade unit designed for 1U rack chassis. It delivers up to 240 watts of DC power and is intended to provide stable, continuous power to CPU, memory, storage, and controller components in compact Supermicro server systems. The unit's 1U form factor and connector layout are made to match slim rack servers where space and airflow are constrained.

Advantages

This 240W 1U power supply offers a balance of power density and thermal efficiency suitable for low- to mid-power server configurations. Its compact size minimizes chassis intrusion while supporting consistent output under sustained load. The design supports typical server power distribution requirements, reducing the risk of unexpected shutdowns and helping maintain system uptime when used as a direct replacement for compatible units.

Suitable for

• Compact 1U rack-mounted servers
• Replacement or upgrade of an existing internal 1U server PSU
• Systems requiring a reliable 240W DC supply for CPU, memory, and drives
• Environments with limited internal space and directed airflow

Key specifications

• Output power: 240 watts
• Form factor: 1U internal server power supply
• Mounting: chassis-internal with standard 1U footprint
• Cooling: designed for chassis airflow (low-profile fan or passive airflow paths depending on server integration)
• Connectors: server power distribution connectors compatible with Supermicro 1U systems (mainboard and peripheral power outputs)
• Intended use: continuous operation for rack server components

How to use

Install the power supply into a compatible 1U chassis following the server manufacturer's procedures: power down the server, disconnect AC power, remove the chassis cover, and slide the unit into the designated bay until it seats and secures with the retention latch or screws. Connect the internal power cables to the system board and drives using the matching connectors. After installation, reconnect AC power and verify that the server completes POST and that voltages are stable in system management or hardware monitoring tools.

Usage recommendations

Confirm chassis compatibility and connector layout before purchase or installation. Use the power supply in environments with adequate airflow and within the server's specified ambient temperature range. When replacing an existing unit, compare mechanical fit and connector types to ensure a direct swap. For critical systems, keep a tested spare PSU available to reduce downtime.
