HPE 460W Common Slot Gold Hot Plug Power Supply | 503296-B21

Brand:

HPE

HPE 503296-B21 460W Common Slot Gold Hot Plug Power Supply Kit is an AC server power supply designed for compatible HPE ProLiant platforms. It delivers up to 460W, supports 100–240V AC input and 50/60Hz, and uses the HPE Common Slot hot-plug form factor. It can serve as a primary or redundant power supply where supported, making it suitable for enterprise server maintenance, replacement, and infrastructure refresh programs.

OVERVIEW

HPE 503296-B21 is a 460W AC Common Slot Gold hot-plug power supply kit for compatible HPE server platforms, providing flexible 100–240V AC input and up to 460W output. Compatibility: verify the exact HPE server model and power configuration before purchase. Compared with HPE 750W 512327-B21, this model provides lower 460W capacity and is intended for systems designed for this PSU class.

USE CASES

HPE server PSU replacement - Restores power availability in compatible legacy ProLiant systems without replacing the complete server.
Redundant power configuration - Can be installed as a primary or redundant supply in supported chassis, helping organizations maintain power redundancy.
Data center hardware refresh - Provides a like-for-like 460W Common Slot replacement for supported HPE infrastructure.
Enterprise server maintenance - Gives IT teams a defined HPE option number for spare-parts planning and lifecycle support.
Server fleet standardization - Using the specified HPE PSU across compatible systems can simplify inventory identification and replacement workflows.
Infrastructure repair programs - Useful where an existing Common Slot PSU requires replacement rather than a complete server upgrade.
Multi-voltage data center environments - 100–240V AC input supports common enterprise power environments without limiting deployment to one nominal voltage.

KEY FEATURES

460W maximum rated output - Provides up to 460W of server power for compatible HPE configurations, making it a practical replacement for systems specified for this capacity.
HPE Common Slot design - Uses the Common Slot power-supply architecture, helping simplify replacement within supported HPE server platforms.
Hot-plug capability - Allows the PSU to be designed for hot-plug server configurations, supporting serviceability and minimizing disruption where the host platform supports redundant hot-plug power.
Gold efficiency class - HPE identifies the unit as a Common Slot Gold power supply, with measured efficiency reaching up to 91.5% at maximum rated output at several supported input voltages.
100–240V AC input - Supports a broad enterprise AC voltage range, providing deployment flexibility across standard data-center electrical environments.

Why Choose This Product?

Exact HPE option identification - SKU 503296-B21 gives procurement teams a precise part number for sourcing and replacement.
460W capacity for matched systems - Avoids unnecessarily specifying a higher-wattage PSU when the target HPE server is designed for 460W.
Hot-plug architecture - Supports serviceability in compatible redundant-power server configurations.
Broad AC input range - 100–240V input accommodates common enterprise electrical environments.
Gold-class design - Provides an efficiency-focused PSU option within the HPE Common Slot family.
Useful for legacy infrastructure support - Particularly valuable when maintaining established HPE ProLiant server fleets and extending hardware service life.
Multiple identifying numbers - Generic part 499249-001 and spare part 511777-001 provide additional procurement cross-reference points.
Better replacement accuracy - Matching the option number and supported server configuration reduces the risk of purchasing an incompatible power supply.
