ASUS GPU Tweak III Update Adds Auto Shutdown for 12V-2×6 Power Spikes

ASUS updates GPU Tweak III to automatically shut down PCs if 12V- 2x6 connector current exceeds 12.5 amps, protecting supported ROG and Matrix GPUs.

ASUS has updated its GPU Tweak III software to protect your rig from dangerous power spikes. This update matters because high current through the 16-pin connector can damage hardware or cause instability. The new safety mechanism acts as a circuit breaker for your graphics card.

New software safety mechanism prevents hardware damage from excessive current draw

The update arrives in version V.2.1.8.0 of the overclocking utility. It targets ASUS graphics cards equipped with the Power Detector+ hardware feature. Current support is limited to the ROG Astral, Matrix RTX 5090, and Matrix RTX 4090 models.

The core function monitors the 12V-2×6 power connector for excessive current draw. If the system detects more than 12.5 amps, it triggers an automatic shutdown. This threshold is designed to prevent damage from wiring faults or connector issues.

Users must manually enable the feature in the software interface. The shutdown is not immediate; the system waits for a configurable countdown timer. This gives users a brief window to intervene if the trigger is a false positive.

This update adds a critical safety layer for high-end ASUS GPUs. The feature remains disabled by default to avoid accidental interruptions. Owners of supported cards should check the settings to ensure their hardware is protected.
