Ideal Replacement for HP and Compaq Desktops

This Bestec ATX-250-12Z-D2R power supply is a genuine 250W unit built to replace failed units in Compaq Presario and HP Pavilion desktops. It matches the HP part number 410507-001 and the D2R revision adds SATA power ports for more modern drives. The 24-pin ATX and 4-pin ATX12V connectors fit the original motherboards directly.

Fixed 250W Output and Manual Voltage Selection

The supply delivers a maximum of 250 watts, which limits it to the original low-power configurations of the listed Compaq and HP models. Input voltage must be set manually using the 115/230V switch before connecting to the mains. Builders needing more headroom for upgraded graphics cards or additional drives cannot use this unit.

Compact Steel Chassis with Ball-Bearing Fan

The enclosure measures 5.9 by 3.4 by 5.5 inches and weighs 3 units, fitting the standard ATX mounting points of the target chassis. A single ball-bearing fan provides cooling through the rear grille. The cable set includes one floppy, two Molex and two SATA power connectors, covering the drive complement of the compatible SR and DX series desktops.
