Applications
ATX desktop power supplies of this class were widely used in IBM desktop computer systems of the late 1990s, providing regulated multi-rail DC power to the motherboard, hard drives, optical drives, and floppy drives. This unit is a direct replacement or spare for IBM desktop platforms that specified the 12J5991 FRU or 12J5990 part number, and is also suitable for legacy system restoration or repair projects requiring a 90W ATX supply with compatible output ratings.
This IBM 12J5991 / Delta DPS-145PB-73 90W ATX Desktop Power Supply has been tested at our facility and is in good working order. The unit is cosmetically consistent with normal used surplus equipment — the steel housing shows light surface scuffs and handling marks typical of a pulled desktop component, but there is no cracking, denting, or significant damage. All output cables and connectors, including the 20-pin ATX main connector, Molex peripheral leads, and floppy connectors, are present and in good condition. The rear IEC power inlet and voltage selector switch are intact. Please view our photo set and contact us if you have any questions.
