This new genuine OEM unit replaces the original power supply in compatible Dell Optiplex, Vostro, Inspiron and Precision mini-tower desktops. It delivers 300 watts through a standard AT form factor and includes the factory cable harness for a direct swap.

Compatibility Check Before Ordering

Verify that your chassis accepts an AT-type mini-tower supply and that the 24-pin ATX main connector matches your motherboard. Count the available drive bays: the harness provides four SATA power plugs and one 4-pin (2x2) CPU connector, so ensure those match your storage and processor requirements.

Rated at 300 watts maximum output, the supply runs within its original thermal envelope for the listed Dell systems. The internal fan operates at stock speeds, producing the same acoustic profile as the factory unit under typical office workloads.
