IBM 6447192 AA12156 AT Power Supply IBM PC XT 5160 Desktop 110V 3A w/ Switch
The IBM 6447192 (model AA12156) is an original AT-style power supply pulled directly from an IBM PC XT 5160 desktop computer. It features an integrated hard-wired On/Off rocker switch mounted to the side of the unit — a distinctive characteristic of early IBM PC power supplies that predates the soft-switched ATX standard. The unit has been bench-tested at our facility and confirmed to be in working order, successfully booting our 486 test motherboard to BIOS.

Applications
The IBM PC XT 5160 was IBM's second-generation personal computer, introduced in 1983 as a successor to the original IBM PC 5150. It used an AT-style power supply with a distinctive side-mounted hard power switch rather than the later soft-switched ATX architecture that became standard in the mid-1990s. This power supply delivers the +5V and +12V rails required by XT-era ISA cards, full-height 5.25-inch floppy drives, and early MFM/RLL hard drives. Today, units like this are sought by vintage computing enthusiasts restoring IBM PC XT 5160 systems, collectors maintaining working examples of early 1980s IBM hardware, and hobbyists building period-correct XT-class machines. The pass-through IEC outlet on the rear was used to power the IBM monochrome or CGA monitor directly from the system unit — a common arrangement of that era.
This IBM 6447192 AA12156 AT power supply has been bench-tested at our facility and confirmed to be in working order — it successfully booted our 486 test motherboard to BIOS. The stainless steel chassis shows light surface wear and patina consistent with its age, as visible in our photos. The on/off switch, output connectors, and wiring harness are all intact and functional. Please view our photo set and contact us if you have any questions.
