HPE 500W Flex Slot Platinum Power Supply | 94% Efficiency | Hot Plug | 865408-B21

HPE 500W Flex Slot Platinum Hot Plug Low Halogen Power Supply Kit (865408-B21)

The HPE 500W Flex Slot Platinum Hot Plug Low Halogen Power Supply Kit (865408-B21) is an enterprise-grade server power supply designed to deliver reliable and efficient power to compatible HPE server and storage platforms. It provides a maximum rated output of 500W and is part of HPE’s Flexible Slot Platinum Power Supply family.

The power supply uses a Platinum-rated design with efficiency of up to 94%. HPE states that Flex Slot Platinum power supplies support power efficiency of up to 94%, helping reduce power waste and improve energy efficiency in supported data center environments.

The HPE Flex Slot form factor is approximately 25% smaller than the previous-generation HPE Common Slot design. The compact form factor helps provide additional internal space for other server options while maintaining the required power capacity for compatible systems.

The hot-plug design provides fast, tool-less access to the power supply, simplifying installation, removal and servicing in supported server configurations. This helps improve serviceability and can reduce maintenance effort in enterprise data center environments.

The P/N 865408-B21 features low-halogen construction and uses a standard C-14 power inlet connector. HPE lists this model specifically as the HPE 500W Flex Slot Platinum Hot Plug Low Halogen Power Supply Kit

HPE’s Flexible Slot documentation identifies the family for use with HPE ProLiant Gen10, Gen10 Plus and Gen11 servers, selected HPE Apollo Gen10 and Gen10 Plus systems, and HPE Alletra 4100 data storage servers. Exact compatibility depends on the server model and configuration, so the applicable HPE QuickSpecs should be checked before installation.

HPE also notes that power supplies installed within the same server should have the same output and efficiency ratings. In addition, HPE specifies that its Low Halogen Power Supplies are not compatible with HPE Gen9 servers. These compatibility requirements should be considered when replacing or adding a power supply to an existing system.

The HPE 865408-B21 is therefore well suited as a replacement or additional power supply for compatible HPE enterprise server configurations requiring 500W output, Flex Slot compatibility, Platinum efficiency and hot-plug serviceability.
