Internal Power Supply Unit (PSU)
The internal switching power supply converts AC wall current to DC rails for the console. Failure occurs when internal MOSFETs or capacitors fail due to heat soak or voltage spikes, resulting in zero output to the motherboard. This component-level failure prevents the console from initializing any standby power states.

Power Button RF Board
This board contains the tactile power switch and the logic circuitry required to signal the motherboard to boot. If the switch fails mechanically or the logic-level controller on this daughterboard malfunctions, the 'Power-On' request never reaches the main processor, leaving the console in a non-responsive state.

Xbox Series X Mainboard
A shorted MOSFET or ceramic decoupling capacitor on the 12V power rail will create a low-impedance path to ground. When the user attempts to power the device, the PSU detects this massive current draw and engages its internal safety shutdown (OCP) within milliseconds, mimicking a 'dead' unit.
