PowerEdge R620 495W Supply

This new 495 W server power supply carries Dell part number N24MJ and model D495E-S0. It accepts 100-240 V AC input and is built for the PowerEdge product line. The unit is designed as a direct replacement or spare for compatible Dell servers.

Fits R620 R720 R520 T320 T420 T620

Compatible models include the PowerEdge R620, R720, R520, T320, T420 and T620. It suits administrators maintaining those specific platforms or keeping a cold spare on hand. Builders working with other server chassis, different form factors or non-Dell hardware should look elsewhere.

Hot-plug redundancy ready

The supply slides into the standard PowerEdge hot-plug bay so a failed unit can be swapped without shutting down the host. It draws AC power from a 100-240 V source and delivers up to 495 W to the system backplane. No extra cabling or adapters are required beyond the server’s own power distribution board.

Questions about this item

Which Dell server chassis must I already have so the D495E-S0 N24MJ supply will physically fit and connect?

The unit is listed for PowerEdge R620, R720, R520, T320, T420 and T620 chassis; one of those models is required for the supply to mount and plug in correctly.

Can the 495W D495E-S0 run in a redundant pair with the original supply that came in my R620?

The R620 supports hot-plug redundant power; a second 495W unit of the same D495E-S0 / N24MJ type will share the load and maintain operation if one module fails.

What front-panel indication confirms the N24MJ module is delivering power after installation?

A solid green LED on the supply face shows normal 100-240 V input and 495W output; amber or off means a fault or missing AC.
