2000 W Hot-Swap Server Power Supply

This Lenovo ThinkSystem unit delivers 2000 W of output power for rack-mount servers. It supports 120 V AC and 230 V AC input voltages. The platinum-rated efficiency reduces waste heat under continuous operation. It is built for hot-swap replacement in redundant power configurations.

Sustained-load behaviour

Platinum-rated efficiency keeps conversion losses low during continuous 2000 W delivery. Hot-swap design allows a failed module to be replaced without shutting down the server. Dual-voltage input maintains stable output whether fed from 120 V AC or 230 V AC sources. The unit is engineered for uninterrupted operation in redundant power arrays.

Pre-order checks

Verify that your server chassis accepts this specific ThinkSystem power module form factor. Confirm the system’s power budget matches the 2000 W rating per module. Ensure the rack power distribution provides either 120 V AC or 230 V AC as required. Buyers needing a different wattage or non-hot-swap design should look elsewhere.

Questions about this item

How much heat and fan noise should I expect when this 2000 W Platinum unit runs continuously at 230 V?

At 230 V the supply delivers up to 2000 W with Platinum-rated efficiency, so waste heat is a small fraction of the load you place on it; fan speed ramps with temperature and power draw.

What server chassis or mounting hardware must I already have to install this hot-swap power module?

It is a hot-swap power module designed for Lenovo ThinkSystem servers that accept a 2000 W Platinum unit; the chassis must provide the matching bay and backplane connector.

Will this power supply work in an older rack that only offers 120 V circuits?

Yes, the input range covers both 120 V AC and 230 V AC, so it can operate on the older 120 V circuits, though maximum output may be limited by the lower voltage.
