Dell KNHJV 750W Server Power Supply

This Dell KNHJV unit delivers 750 W of power for compatible Dell PowerEdge rack servers. It is designed for IT administrators maintaining or expanding enterprise server infrastructure. The supply accepts 120 V AC and 230 V AC input, making it suitable for standard data-centre power distribution.

Thermals noise and power draw

The power supply operates from 120 V AC or 230 V AC mains input and provides up to 750 W of output power to the server. Internal cooling is managed by the server chassis airflow, so acoustic and thermal performance depend on the host system configuration. No separate fan or thermal specifications are provided for the module itself.

Build integration and compatibility

This module fits Dell PowerEdge R630, R640, R730, R730XD, R740 and R740XD rack servers. It occupies a standard hot-plug power-supply bay and requires no additional cabling beyond the server backplane connection. Builders needing redundant power should verify the server supports multiple units, while those using non-Dell chassis or different PowerEdge models cannot use this supply.

Questions about this item

How do I install the Dell KNHJV 750W power supply in a compatible PowerEdge server and what step is often missed?

Slide the unit into the hot-plug bay until the latch clicks; the step often missed is verifying the green AC-OK LED lights on both the module and the system LCD to confirm full seating.

What maintenance or replacement will the Dell KNHJV 750W power supply need during its service life?

Periodically vacuum the intake mesh to prevent dust buildup on the internal fan; the fan assembly is the only field-replaceable component and should be swapped if bearing noise appears.

What is the first limit reached when the Dell KNHJV 750W power supply runs at full load continuously?

The 750 W output ceiling is reached first; once the combined rail draw hits 750 W the unit enters over-current protection and shuts down until the load drops.
