Internal Power Supply Unit (PSU)
The internal power supply is a switching-mode power supply (SMPS) responsible for converting high-voltage AC mains to a stable 12V DC rail. Failure typically occurs due to thermal stress or component degradation (such as capacitors or bridge rectifiers) within the PSU housing, preventing the console from receiving any electrical current to initiate the boot sequence. Replacing this module restores the primary power rail to the motherboard.

Power Rail MOSFET
If the PSU is functional, the failure often lies in the MOSFETs (Metal-Oxide-Semiconductor Field-Effect Transistors) on the motherboard that control high-current power switching. A short-circuit in these components creates a low-impedance path to ground, triggering the PSU's over-current protection (OCP) and causing the console to remain in a 'dead' state to prevent further damage.
