Compatible Server Power Supply

This 495 watt unit is built for PowerEdge R730, R530 and R630 servers. It delivers the rated output through a redundant hot-swap form factor designed for rack environments. The part carries identifiers D495E-S1 and N24MJ for exact matching.

Suited For Direct Replacement

Administrators maintaining the listed PowerEdge models can install this supply without adapter cables or firmware changes. Builders assembling custom chassis or upgrading to higher-wattage configurations should verify their platform accepts this specific form factor and connector pin-out before ordering.

Ready To Install

The module ships as a complete hot-swap cartridge including its internal fan and latch mechanism. No separate mounting brackets, cables or management software are bundled, so deployment is limited to sliding the unit into a compatible bay and securing the release lever.

Questions about this item

Which Dell PowerEdge chassis does the D495E-S1 N24MJ fit directly into?

The unit is built for PowerEdge R730, R530 and R630 servers and slides into their standard redundant PSU bays without an adapter.

Can this 495W PSU share a load with an older 450W unit in the same server?

Dell’s redundant design allows mixed-wattage supplies; the system will draw up to the lower unit’s 450W limit while both are present.

What front-panel indicator confirms the D495E-S1 is delivering power after installation?

A solid green LED on the supply’s faceplate lights when the module is seated, receiving AC and outputting DC to the backplane.
