HPE P27749-B21 3000W Titanium Hot-Plug Redundant Power Supply Kit

Overview

The HPE P27749-B21 is a 3000W hot-plug redundant power supply kit engineered for high-density HPE server platforms where power continuity and efficiency are non-negotiable. At 3000W, this unit targets compute-heavy deployments — AI inference nodes, dense virtualization hosts, or storage-heavy rack configurations — where a single PSU failure cannot be allowed to interrupt operations. The hot-plug design means a failed unit can be swapped under full server load without scheduling downtime, which matters in 24/7 data center and surveillance back-end environments. The Titanium efficiency rating (80 PLUS Titanium) translates to less heat generated per watt delivered, reducing cooling load in dense rack configurations and lowering operating costs over the system lifecycle.

Compatibility

The P27749-B21 is designed for HPE ProLiant server platforms that support the high-wattage hot-plug redundant PSU form factor at this power class. Verify compatibility against your specific ProLiant chassis model — HPE's QuickSpecs for your server will confirm whether the 3000W Titanium slot is supported and whether a redundant pair configuration is required. This kit is not a universal fit; PSU form factor, connector type, and wattage ceiling are chassis-specific. Confirm your server's maximum PSU wattage and bay count before ordering.
