Direct replacement for Dell R210

This 250 W server power supply is built to fit the Dell R210 chassis. It carries the NPS-250LB model designation and matches the original part numbers L250E-S0, PS-4251-1D-LF, C627N and D221N. The unit ships new and ready for installation.

Replaces a failed or degraded original unit

When the factory supply shows voltage drift, fan noise or complete loss of output, this module restores the specified 250 W capacity without modification. The swap is worthwhile when uptime requirements exceed the risk of running on ageing hardware.

Limited to Dell R210 compatibility

The mechanical keying, connector pin-out and firmware handshake are specific to the R210 platform. Builders using other server models, workstation chassis or custom enclosures will find the unit physically or electrically incompatible.

Questions about this item

Will the NPS-250LB slide into a Dell R210 chassis without an adapter bracket?

The NPS-250LB is built to the Dell R210 form factor and mates directly with the server's power backplane; no extra bracket is required.

Which orientation do I insert the NPS-250LB so the latch clicks on the first try?

Hold the unit with the label facing right, push straight in until the metal tab engages the chassis catch, then press the release lever down to lock it.

How often should I clean the intake vents on the NPS-250LB to keep temperatures stable?

Vacuum the front mesh every three to six months, or sooner in dusty racks, to prevent airflow restriction on the 250 W unit.
