HP 5188-2622 Bestec ATX-250-12Z 250W 20-Pin Power Supply

HP 5188-2622 is a 250-WATT internal desktop power supply associated with Bestec ATX-250-12Z revisions and selected HP Pavilion and Compaq Presario systems. HP parts information reports switch-selectable 100-120 or 200-240 VAC, 50/60 Hz input, while exact-part evidence identifies a 20-PIN ATX main connector on common D7R revisions. Some related ATX-250-12Z listings describe 20+4-PIN variants, so connector count cannot be assumed from the model family alone. Power cord, mounting hardware, and accessories are not assumed included. This inventory record explicitly identifies the condition as New. Match 5188-2622 exactly and verify the desktop product number and serial, complete HP/Bestec label, ATX-250-12Z model and revision, 250-WATT rating, voltage-switch setting, output rails, dimensions, mounting, exact motherboard-plug size and keying, every connector and cable, fan, and pinout before ordering.
