SONY PLAYSTATION 5 Turning Off Randomly

Internal Power Supply Unit (PSU)

The PS5 PSU is positioned in the airflow path where dust frequently bypasses the main filters and clogs the internal PSU ventilation holes. When the console runs high-load AAA titles, the PSU's internal MOSFETs and capacitors reach critical temperatures, triggering a hardware-level thermal shutdown to prevent catastrophic electrical failure.

Internal Cooling Fan (23-Blade High-Efficiency)

Mechanical degradation of the fan bearings or dust accumulation on the impeller blades reduces the Cubic Feet per Minute (CFM) of airflow across the heatsink stack. This results in heat soak within the chassis, eventually exceeding the thermal threshold of the system's thermistors and forcing a safety shutdown.

CR2032 Lithium 3V Coin Cell

The CMOS battery maintains the system's power-state logic and internal clock. Research indicates that a low-voltage or unstable coin cell can cause the System Controller (Syscon) to misinterpret power signals, leading to erratic shutdowns during transitions between power states or high-activity gaming.
