Dell 495W Redundant PSU for R720XD

This Dell 495W redundant power supply is built for the PowerEdge R720XD server. It delivers 495W of power in a hot-swap form factor that supports N+1 redundancy. The unit weighs 5.0000LBS and carries manufacturer part numbers 3GHW3, N24MJ and W4TTH. It is sold new with a 90 day warranty.

Hot-swap redundancy limits

The supply fits the R720XD chassis and shares load with a second identical unit for failover. Removing one module while the server runs is supported only when the second module is present and healthy. Total available power remains 495W; the redundant partner does not increase the wattage ceiling. The 90 day warranty covers the power supply itself.

Check R720XD bay and firmware

Verify that your R720XD has a free redundant PSU bay and that the system firmware recognises the part numbers 3GHW3, N24MJ or W4TTH. Confirm the server is not configured for a higher-wattage primary supply that would prevent this 495W unit from seating correctly. Buyers who need more than 495W total power or a non-redundant single supply cannot use this module.
