Lenovo ThinkServer Gen 5 750W Power Module

The Lenovo 4X20F28576 is a 750 watt hot-swap power module designed for ThinkServer Gen 5 systems. It delivers redundant, enterprise-grade power for rack-mounted workloads that require continuous uptime and flexible scaling.

80 Plus Platinum efficiency and thermal profile

Rated at 80 Plus Platinum by TÜV, the unit converts mains power with minimal waste heat during normal operation. Hot-swap capability lets technicians replace the module without powering down the server, reducing thermal disruption and acoustic impact in the rack.

Hot-swap redundancy changes maintenance workflow

The hot-swap design allows a failed or upgraded module to be exchanged while the server remains online, eliminating planned downtime for power maintenance. This capability supports field-proven reliability for environments that cannot schedule service windows.

Questions about this item

How do I install the 750W hot-swap power module in my ThinkServer Gen 5?

Slide the unit into an empty bay until the latch clicks; the step people miss is not pushing firmly enough to fully seat the connector.

What maintenance will the 750W Titanium supply need over its life?

Periodically vacuum the intake vents and check the fan spins freely; the hot-swap design lets you replace the module without shutting down the server.

What limit appears first when the 750W supply runs continuously at full load?

Thermal protection will throttle output if inlet air exceeds the server's rated operating temperature, so keep airflow clear.
