Compatibility with Lenovo ThinkServer Models

This power supply is designed as a direct replacement for the Lenovo ThinkServer TS440, TS540 and TS530 systems. It delivers 450W of continuous ATX power to keep these servers running reliably. The unit matches the original form factor and connector layout required by these specific chassis. It is not suitable for standard desktop ATX cases or non-ThinkServer platforms.

Verify Part Numbers and Connector Layout

Before ordering, confirm that your server requires one of the listed part numbers such as 03X4373, 36002293 or 0A92052. Check that the existing unit uses the same proprietary connector arrangement as the original ThinkServer design. Ensure the chassis can accept a standard ATX-type supply with the correct mounting points for these models. Buyers needing redundant or hot-swap power modules for other server lines cannot use this unit.

80 PLUS Gold Efficiency and Silent Operation

The 80 PLUS Gold certification ensures high efficiency across typical server loads, reducing heat output and electricity costs. Modern Standby compatibility allows extremely fast wake-from-sleep transitions for supported operating systems. A Zero RPM fan mode stops the fan completely at low and medium loads for near-silent running. Resonant LLC topology with DC-to-DC conversion delivers clean power and minimises coil whine.
