Power supply HP Enterprise 1600W Flexible Slot 863373-001-RFB

Replacement server power supply designed for HP Enterprise systems, offering 1600W output in a Flexible Slot form factor. This unit provides stable AC-to-DC conversion for compatible HPE servers and is suitable for use in redundant or single-power configurations. The module supports hot-swap installation to reduce service interruptions and is intended for data center and enterprise server environments that require reliable, high-capacity power delivery.

Advantages

The 1600W Flexible Slot power supply delivers high continuous wattage while occupying a compact slot profile, allowing flexible capacity scaling in multi-bay server chassis. Hot-swap support enables replacement without shutting down the server, helping maintain uptime. Built-in protections for overcurrent, overvoltage and short-circuit conditions contribute to system stability. The form factor is engineered for straightforward integration into compatible HP Enterprise server platforms, simplifying maintenance and deployment.

Suitable for

• Enterprise rack servers requiring high-power PSU modules
• Redundant power configurations in data centers
• Server refresh or field replacement operations
• Environments where hot-swap capability is required

Key specifications

• Output power: 1600 watts continuous
• Form factor: Flexible Slot server power supply
• Input: AC mains compatible with targeted server platforms
• Cooling: active cooling compatible with server chassis airflow

How to use

Verify compatibility with the target HP Enterprise server model and power requirements before installation. Power down the server or follow the server vendor’s hot-swap procedure if live replacement is supported. Remove the existing module by releasing the latch or fastener, then insert the replacement power supply into the slot until it seats and the retaining mechanism engages. Restore AC mains connection and confirm the server recognizes the module and that system diagnostics report normal power status. Follow any vendor-specific firmware or management interfaces to monitor PSU health.

Usage recommendations

Install identical or compatible power modules in redundant configurations to ensure balanced load sharing. Maintain proper rack airflow and ambient temperature within the server manufacturer’s specified range. Use trained personnel for hot-swap replacement and observe electrostatic discharge precautions.
