Apple Macintosh LC PSU (661-0732)
Apple Macintosh LC 45 W supply assembly Apple part 661-0732 (OEM variants exist). This entry covers the specific model or bounded historical system assembly identified here; suffixes and supplier revisions are not presumed equivalent.
HIGH-VOLTAGE SAFETY: Disconnect mains before external inspection. Never open a PSU. Internal capacitors can retain dangerous charge after disconnection. Do not probe or repair its interior; use qualified service or replace it.

Compatibility & safe handling
- Verify full model, suffix, region and revision using the actual unit nameplate and matching manufacturer manual. Wattage and plug shape alone do not establish compatibility.
- Check AC input range, rail and combined output limits, derating, signaling/pinout, cooling direction, mounting and system qualification before installation.
- PSU modular-side cables are model-specific. Never reuse an unapproved lead; a matching plug can carry a different pinout.
- Server hot-plug is permitted only in qualified host configurations and under the host’s documented redundancy/live-service procedure.
- Never open or internally probe the supply. Retire damaged, wet, burnt, corroded, modified or unidentified units.
Revision & archival notes
Apple documented multiple vendors (Astec AA15081, Delta DPS-120GB A, Sony APS-06) and part revisions under the LC supply family; record actual supplier/model.
Use the Apple LC service source/technical note and PSU manufacturer label; the family contains distinct vendor assemblies. Keep identification separate from measured condition.
Photograph the full nameplate, model/FRU, supplier, revision/date code, line selector, cable ends, mounting orientation and source-document issue. Keep observed label data separate from test results.
