Fuente de alimentación HPE 511778-001 750W 1U

The HPE 511778-001 750W 1U power supply unit provides up to 750 W of continuous power for compatible HPE server systems. Designed in a compact 1U form factor (86.3 mm × 190.5 mm × 38.1 mm) and weighing approximately 1.36 kg, this PSU supports an AC input voltage range of 100–240 V and carries an 80 PLUS Gold efficiency certification. The unit is intended to deliver stable power in rack-mounted or space-constrained server environments and is compatible with a range of HPE server models that accept this modular supply.

Advantages

The 80 PLUS Gold certification indicates improved energy efficiency, reducing power loss and cooling requirements compared with lower-efficiency units. The compact 1U dimensions make the PSU suitable for high-density rack installations. With a rated total power of 750 W and a broad AC input range of 100–240 V, the unit offers reliable power delivery and flexibility for different regional power systems. The moderate weight (about 1.36 kg) and standardized mounting enable straightforward installation and replacement in compatible servers.

How to use

Before installation, power down the server and disconnect the system from the mains supply. Verify compatibility with the server model and confirm the part number matches required specifications. Slide the PSU into the designated 1U bay or module slot and secure any locking mechanism according to the server manufacturer’s instructions. Connect the internal power connector(s) if required and restore mains power. Monitor the server after power-up to ensure the PSU is recognized and operating within normal parameters.

Recommendations

Use this PSU in environments that meet the server’s recommended operating conditions, including adequate ventilation and ambient temperature limits. For redundancy, consider deploying with redundant power configurations where supported by the server. Replace the unit with an identical or manufacturer-approved part (MPN 511778-001-RFB) to maintain compatibility and efficiency; observe electrostatic discharge precautions during handling.
