Lenovo 4P57A75973 virtalähde 750 W musta, metallinen

The Lenovo 4P57A75973 750 W power supply unit delivers up to 750 watts of continuous power for server environments with a 230 V AC input. Engineered for high-efficiency operation, the unit holds an 80 PLUS Titanium certification to minimize energy losses and reduce operational costs. The chassis combines black and metallic finishes and integrates active cooling to maintain stable performance under continuous load.

Advantages

This power supply provides high conversion efficiency certified by 80 PLUS Titanium, resulting in lower heat generation and reduced electricity consumption. With a 750 W output it supports demanding server configurations and workloads. The active cooling system helps keep internal temperatures within operational limits, promoting reliability and longer component life. The compact chassis with a black and metallic appearance is designed to fit typical rack-mounted or tower server installations.

Suitable for

• Rack-mounted and tower servers requiring a reliable 750 W PSU
• Data center and enterprise use where high-efficiency power supplies are preferred
• Environments with continuous or high-load operation
• Systems where thermal management and component longevity are important

Key specifications

• Total output power: 750 W
• AC input voltage: 230 V
• Efficiency certification: 80 PLUS Titanium
• Cooling method: active cooling (internal fan)
• Colour and finish: black and metallic

How to use

Install the power supply into a compatible server chassis following the server manufacturer’s installation instructions. Ensure the AC input is connected to a properly grounded 230 V outlet and that the PSU is secured in the drive bay or PSU tray. Verify connectors and cable routing to match the server’s power input requirements, and power on the system while monitoring initial startup for stable voltages and expected fan operation.

Recommendations

Operate the unit within the specified AC input range and ambient temperature limits typical for enterprise servers. Maintain adequate airflow around the chassis and perform periodic dust cleaning of intake and exhaust areas to preserve cooling efficiency. Use this PSU in systems where its 750 W rating meets or slightly exceeds the expected continuous load to avoid prolonged operation near maximum capacity.
