Power supply unit Lenovo THINKSYSTEM 500W 230V/115V – internal server PSU 500 W, dual voltage

Lenovo THINKSYSTEM 500W 230V/115V is an internal power supply unit designed for server and data-center use. Delivering up to 500 watts of continuous DC power, this PSU supports dual input voltage (230V and 115V) to accommodate different regional mains standards. It is intended as a direct replacement or upgrade for compatible Lenovo rack and tower servers, providing regulated power to processors, memory, storage controllers and expansion cards in enterprise environments.

Advantages

This internal server power supply offers stable power delivery with 500 W nominal output, reducing the risk of system instability under load. Dual-voltage input allows flexible deployment across locations with either 230 V or 115 V mains. The compact internal design is compatible with space-constrained server chassis and facilitates straightforward installation or replacement without modifying server infrastructure. Built to meet server-class reliability expectations, the unit helps maintain uptime in business-critical applications.

Suitable for

• Replacing or upgrading PSUs in compatible Lenovo rack or tower servers
• Small to medium data center nodes requiring a 500 W internal PSU
• IT maintenance tasks where dual-voltage support (230 V / 115 V) is needed
• Systems powering processors, memory, storage controllers and expansion cards

Key specifications

• Output power: 500 W nominal DC output
• Input voltage: dual-range support for 230 V and 115 V AC
• Form factor: internal server power supply compatible with Lenovo server chassis
• Cooling: chassis-integrated cooling (server fan assisted)
• Use environment: designed for enterprise server and data-center operation

How to use

Install the PSU into the compatible Lenovo server chassis following the server manufacturer's instructions and safety procedures. Ensure the system is powered off and disconnected from mains before replacing the unit. Secure the supply in its mounting location, connect the internal power connectors to the motherboard and peripherals, and attach the correct AC input cable for the local mains voltage. After installation, power on the server and verify stable operation and any server management indicators for PSU status.

Recommendations

Use this power supply in systems where the total component power draw does not exceed the 500 W rating, and confirm compatibility with the server model before installation. For redundant configurations or higher-power systems, consider using additional or higher-capacity PSUs. Maintain recommended operating temperatures and ensure adequate airflow in the chassis to preserve reliability.
