IBM 5160 PC/XT 130 W power supply
IBM Personal Computer XT model 5160 OEM PSU, 130 W class. This record is bounded to the named unit, standard revision, or model family below; nearby model names and replacement parts are not presumed equivalent.
HIGH-VOLTAGE SAFETY: Unplug before external inspection. Never open a power supply. Dangerous voltage can remain inside after it is disconnected. Do not attempt internal repair; use qualified service or replace the unit.
Verified identity & specifications
| Catalog identity | IBM Personal Computer XT model 5160 OEM PSU, 130 W class |
|---|---|
| Form factor / era | XT-era proprietary PSU |
| AC input | IBM 5160 technical reference: line-frequency AC input; exact voltage/frequency/current are nameplate and region dependent. |
| DC output rating | The 5160-era label and IBM technical reference govern rail limits; 130 W is the supply rating class, not a guarantee for every OEM assembly. Do not infer rail amperage from wattage. |
| Mechanical envelope | Chassis-specific, full-width XT supply; verify mounting, depth, air path, and rear AC inlet against the actual 5160 case. |
| Connectors / interface | Proprietary motherboard harness; not ATX. Compare the pinout/polarity against the exact IBM/OEM manual before any replacement. |
| Revision differences | 5160 supplied OEMs and assembly labels varied; identify the maker, assembly number, and DC-output label rather than treating “130 W” as a universal revision. |
Compatibility & safe handling
- Match full model, suffix, region, revision and DC output label to the official documentation. Rated total watts alone do not establish rail or transient compatibility.
- Before replacement, confirm AC input range, rail current/combined limits, motherboard signaling and pinout, mechanical envelope, fasteners, cooling direction, and every required connector.
- Never open the PSU, defeat protective earth, or probe its internals. Do not energize a wet, cracked, corroded, burned, modified, or unidentified supply.
- Modular cable pinouts are not standardized at the PSU end. Use only cables expressly approved for this exact model/revision; matching plugs can have different wiring.
Model and revision notes
5160 supplied OEMs and assembly labels varied; identify the maker, assembly number, and DC-output label rather than treating “130 W” as a universal revision.

Archival notes
Record the 5160 type/model, PSU label, OEM, date code, fuse/selector state, cable condition, and the technical-reference revision used. The schematic image is an original archival block diagram, not a service drawing.
Photograph the complete nameplate, assembly/model code, revision/date code, input selector if present, cable ends and mounting side. Separate observed label data from published specifications and preserve the referenced manual issue.
