DELL PS-5251-01DI PSU Power Supply 250W (USED LIKE NEW)

This Dell PS-5251-01DI is a 250-watt internal power supply designed specifically for compact and small-form-factor desktop systems. It offers a quiet but efficient solution to deliver the required power for everyday workloads in enterprise or consumer machines without excess bulk. The form-factor is tailored to fit in Dell’s SFF towers and slim desktops, ensuring that the unit integrates seamlessly into tight spaces and aligns with OEM design constraints.

Inside the chassis, the PS-5251-01DI utilizes a fixed-output architecture, meaning that the maximum power capacity is capped at 250 W, which is sufficient for the targeted system configurations. The layout of connectors, internal routing and cooling have been optimized to match Dell’s hardware requirements, reducing installation complexity and ensuring compatibility with the parent system’s power-distribution layout. With its streamlined design, the unit keeps the power supply-impact minimal—both physically and thermally.

In practice, the PS-5251-01DI is used for mainstream systems where power efficiency and reliability matter more than headroom for high-end graphics or overclocked CPUs. It provides a stable power source for standard motherboard, storage and optical-drive combinations, giving system builders and IT departments confidence that the desktop will remain stable under typical load. Dell’s integration means fewer concerns over fit, airflow or connector mismatch. The result is a clean replacement or upgrade path for supported Dell desktops.
