495W Redundant Power Supply for T420

This Dell power supply delivers 495 watts of redundant power to a PowerEdge T420 server. It is a new replacement unit designed to fit the server’s hot-plug bay and maintain uptime during a module failure. The part carries manufacturer numbers 3GHW3, N24MJ and W4TTH.

Capacity and headroom

At 495 watts the module supports a fully populated T420 with multiple drives and expansion cards under typical loads. Redundancy headroom disappears when a second module is not installed or when the combined draw exceeds the single-unit rating. The 5.0000 lb weight reflects a dense internal layout.

Hot-plug redundant form factor

The supply slides into the T420’s redundant bay without tools and shares load with a matching module. Buyers who need a non-redundant or higher-wattage unit for a different chassis cannot use this part. Compatibility is limited to the PowerEdge T420 platform.

Questions about this item

Will the 495W redundant power supply fit in the PowerEdge T420 chassis alongside existing components?

It is built for the PowerEdge T420 and slides into the redundant PSU bay without modifying the chassis.

How can I confirm the 495W unit is operating correctly after installation?

The server's front-panel LEDs and iDRAC interface will show both power supplies as healthy and sharing the load.

Does the 495W redundant power supply include the C13 power cord or must I order it separately?

Only the power supply module is supplied; a standard C13 mains cable must be sourced separately.
