Industrial M5183 Power Supply Module Assembly

Industrial M5183 Power Supply Module Assembly is a replacement power module associated with the Apple Power Mac G4 family (M5183, EMC 1864). This assembly provides the primary AC-to-DC power delivery needed by the G4’s logic board and peripheral rails, serving as the critical link between mains power and the computer’s internal components. It supports worldwide mains compatibility, specified for 120V AC (typical in North America) and 200–240V AC (international markets), with operation at 50–60 Hz. The listed current ratings correspond to 8A at 120V and 4.5A at 200–240V, reflecting the expected load range for this model family. Designed as a direct replacement for M5183-based Power Mac G4 units, this module aligns with Apple service documentation for Power Mac G4 chassis variants identified by M5183 (EMC 1864). It is intended for technicians performing restoration or repair on Power Mac G4 towers that cite the M5183 family, enabling proper boot, power delivery, and stable operation of the system’s motherboard, storage interfaces, and I/O subsystems.
