Direct replacement for Inspiron and OptiPlex

This 290 W desktop power supply carries the Dell N0KPM part number. It is built as a direct replacement for Inspiron 3020, 7020 and 9020 models as well as OptiPlex 9020 MT systems. The unit weighs 3.5 and includes a single cooling fan.

Fixed cable set and 290 W ceiling

The supply is non-modular, so every cable is permanently attached. That limits cable routing options inside smaller chassis. The 290 W maximum output caps the total power available to the motherboard, CPU, drives and any expansion cards combined.

Swaps a failed or insufficient OEM unit

It replaces the original Dell supply when that unit has failed or when a newer configuration demands more headroom than the old one provided. The jump is worth it only if the system stays within the 290 W limit and the fixed cable layout matches the case. Builders needing higher wattage or modular cables must look elsewhere.
