Alimentatore HP 796416-001 400 W non modulare, 92% di efficienza, grigio

HP 796416-001 is a 400 W internal power supply unit designed for desktop PCs. The unit features non-modular cabling and a grey finish. With a rated output of 400 watts and up to 92% energy efficiency, this PSU provides stable power delivery for standard motherboards and common peripheral devices. It is intended for system replacement or repair where compact, reliable 400 W output and efficient operation are needed.

Advantages

The power supply delivers up to 400 W continuous power with high conversion efficiency, reducing energy losses and heat generation. Non-modular cabling ensures all standard connectors are present for straightforward installation, while the grey housing offers a neutral appearance that integrates with most desktop enclosures. Built to meet typical compatibility requirements for mainstream desktop components, the unit provides steady voltage outputs and basic protections expected from OEM power supplies.

Suitable for

• Replacing a failed or aging desktop power supply in compatible HP and third-party chassis
• Repairs and refurbishments of office or home desktop systems requiring 400 W
• Systems with standard ATX connectors and modest power demands (single GPU or integrated graphics)
• Environments where energy efficiency and lower heat output are desired

Key specifications

• Maximum output power: 400 W
• Energy efficiency: up to 92%
• Cabling: non-modular fixed cables with standard motherboard and peripheral connectors
• Form factor: internal ATX-style power supply for desktop systems
• Cooling: internal fan-cooled design to maintain operating temperature
• Finish: grey metal housing

How to use

Before installation, disconnect the computer from mains power and ground yourself to prevent electrostatic discharge. Remove the case side panel, disconnect and remove the existing power supply if present, then position the HP 400 W unit into the PSU bay and secure it with the mounting screws. Connect the main motherboard power connector and any required peripheral connectors (SATA, Molex, CPU power) to the corresponding system components. Verify all connections are secure, replace the case panel, and reconnect mains power before powering on the system to confirm proper operation.

Recommendations

Use this 400 W power supply in systems with moderate power requirements; avoid pairing it with high-end multi-GPU setups or heavily overclocked processors that exceed its rated capacity. Ensure adequate case airflow and periodically check connectors for dust or looseness to maintain reliable performance.
