Product Overview
The HPE 1600W Flex Slot Platinum Hot Plug Power Supply Kit is a strong run-rate spare for HPE ProLiant environments, especially where servers are configured with higher-power processors, large memory footprints, multiple drives, additional PCIe cards or GPU workloads.
Power supplies are one of the most commonly requested HPE server spare parts because they are critical to uptime. Many ProLiant servers are configured with dual power supplies for redundancy, making the P38997-B21 a useful option for repairs, second-PSU upgrades and spare stock.
Why Buy This PSU?
The P38997-B21 is suitable for customers who need to replace a failed HPE power supply, add redundant power, or support a more demanding HPE ProLiant server configuration. Its 1600W output makes it a good choice for higher-spec systems where 500W, 800W or 1000W units may not provide enough power headroom.
Common Use Cases Replacement power supply for compatible HPE ProLiant servers Adding redundant power to supported server configurations High-power HPE server builds GPU, storage-heavy or expansion-card-heavy configurations Virtualisation hosts and business-critical workloads Datacentre spare stock MSP and IT support inventory Server repair and maintenance projects
Compatibility
The P38997-B21 is part of the HPE Flex Slot power supply range and is designed for compatible HPE ProLiant server platforms. Compatibility should always be checked against the exact HPE server model, generation and configuration before purchase.
