About the 4P57A75974

The Lenovo 4P57A75974 is a high-output 1800W AC hot-swap power supply module designed for high-density GPU computing and memory-heavy server nodes. Operating on high-line 200V to 240V AC power with 80 PLUS Platinum energy efficiency, it delivers the electrical capacity required by multi-GPU configurations, high-core-count Emerald Rapids CPUs, and all-flash NVMe storage backplanes.

Compatibility

Compatible with Lenovo ThinkSystem SR650 V2, SR650 V3, SR665 V3, SR670 V2, and ST650 V3 servers. Requires a high-line 200V-240V AC power source and features a C14 power inlet. It cannot operate on standard 110V/120V household AC circuits and will not deliver 1800W output under low-line input voltages.

How to identify a genuine unit

Distinguished by an orange release latch, a heavy-duty extraction handle, and a label listing option part number 4P57A75974, FRU part number 03GX101, and feature code BKP6. When installed, XClarity Controller identifies the module with official Lenovo firmware and displays power factor telemetry.

Buying used

When purchasing a used 1800W power supply, verify that your data center or rack PDU supplies 200-240V AC power. Inspect the edge connector contacts for electrical pitting or heat damage. Confirm that the cooling fan rotates freely and that the unit operates quietly under full server electrical load.
