Applications
The NPS-250KB A was used in Dell OptiPlex and Dimension desktop PCs from the early-to-mid 2000s. Dell desktop systems of that era used a proprietary power supply form factor and connector pinout that differs from standard ATX, making direct-fit replacements like this unit essential for repair and maintenance. This supply is a straightforward drop-in replacement for systems that originally shipped with the NPS-250KB A or L230P-00. It remains in demand for servicing legacy Dell desktops still in office and light-duty use.
This Dell NPS-250KB A (L230P-00) 170W desktop power supply has been bench-tested at our facility and is in good working condition. The unit is clean overall with minor cosmetic wear consistent with normal use. All output connectors — including the 20-pin ATX main, Molex 4-pin, floppy, and auxiliary leads — are intact and in good shape. Please view our photo set and contact us if you have any questions.
