Lenovo 1100W Titanium hot-plug PSU

This Lenovo 4P57A72666 is an 1100 Watt hot-plug redundant power supply certified to 80 PLUS Titanium. It is built as a plug-in module for ThinkSystem ST650 V2 servers carrying model numbers 7Z74 and 7Z75. The unit weighs 1.22 kilograms and ships in black.

Suited for ThinkSystem ST650 V2 redundancy

It suits administrators adding or replacing a power module in a ThinkSystem ST650 V2 7Z74 or 7Z75 chassis that requires hot-swap redundancy. Builders working with any other server platform, desktop case, or non-redundant power architecture should look elsewhere because the form factor and connector layout are specific to these Lenovo models.

1100 Watt 80 PLUS Titanium rating

The single specification that decides fit is the 1100 Watt output with 80 PLUS Titanium efficiency in the ThinkSystem hot-plug module format. If your ST650 V2 configuration calls for that exact wattage and efficiency tier in a redundant plug-in unit, this part matches the requirement.

Questions about this item

Which ThinkSystem server models accept the 4P57A72666 1100W power supply?

This unit is validated for ThinkSystem ST650 V2 models 7Z74 and 7Z75. It slides into the server's redundant power bay and locks with the hot-plug latch.

Can I mix this Titanium-rated supply with an existing Platinum unit in the same ST650 V2?

Yes. The ST650 V2 supports mixed-efficiency redundant supplies; each module shares load independently and the system will report both efficiencies.

What front-panel indication confirms the 1100W module is online and sharing load?

The module's bi-colour LED shows steady green when AC is present, output is within limits, and the unit is actively sharing load with its partner.
