850W ATX 3.0 Gold Power Supply Unit
The RX 7800 XT is known for significant transient power spikes that can trigger Over-Current Protection (OCP) or voltage sags on older power supplies. This causes the 'Default performance tuning settings' error or Event ID 18 reboots as the GPU's VRMs fail to maintain steady voltage during load transitions. An ATX 3.0 PSU is specifically designed to handle 200% power excursions for short durations, resolving these hardware-triggered software errors.

Individual PCIe 8-Pin Power Cables
Using a single 'daisy-chained' pigtail cable to power the 7800 XT's two 8-pin connectors often results in 'Driver Timeout' errors due to excessive heat and voltage drop across the shared wire. Replacing a single cable with two dedicated 18AWG PCIe cables ensures sufficient current flow and reduces impedance-related errors during peak gaming loads.

GPU Replacement Fan Set
If the 'Error' specifically references fan speed or control (as suggested by the 'Cpu Fan' input string), the physical bearings or PWM sensor in the GPU fan assembly may be failing. This triggers a BIOS-level fan error or Adrenalin software crash when the card cannot reach the commanded RPM to maintain the thermal target.
