ASUS has released GPU Tweak III version 2.1.9.5 with a new immediate-shutdown option for graphics cards equipped with Power Detector+. The utility can now power off a system as soon as a configured current threshold is reached, adding another layer of protection for ASUS enthusiast GPUs with advanced connector monitoring.
Key takeaways
- GPU Tweak III 2.1.9.5 adds immediate shutdown when a defined current threshold is reached.
- The feature is available on supported ASUS graphics cards with Power Detector+.
- Power Detector+ monitors current across six individual 12VHPWR or 12V-2×6 connector pins.
- The update also refines the settings interface and addresses stability and localization issues.
Immediate shutdown adds another protection mode
The new checkbox in GPU Tweak III’s Power Detector+ settings allows users to select an immediate system shutdown when the configured threshold is reached. This differs from the earlier protection mode introduced in version 2.1.8.0, which required excessive current to remain present for a user-configured period before beginning a shutdown countdown.
ASUS is positioning the new option as a faster response for users who want the software to react as soon as a potentially unsafe current condition is detected. As with any automatic shutdown feature, enthusiasts should review their thresholds carefully before enabling it.
Monitoring individual power pins
Power Detector+ tracks current across the six individual power pins used by 12VHPWR and 12V-2×6 connectors. ASUS says the existing protection system monitors whether any individual pin exceeds 12.5 amps, while allowing users to configure how long that condition must persist before shutdown begins.
The hardware monitoring feature is currently available on selected ASUS models, including graphics cards in the ROG Astral and ROG Matrix families. It is therefore not a universal capability across all ASUS GPUs or third-party graphics cards.
GPU Tweak III continues expanding Power Detector+
ASUS has added several Power Detector+ improvements through recent GPU Tweak III releases. Version 2.1.7.2 introduced persistent, real-time amperage readings for individual pins, followed by automatic shutdown protection in version 2.1.8.0. Version 2.1.9.5 extends that system with a selectable immediate-response mode.
The latest release also redesigns part of the Power Detector+ settings interface and includes general stability improvements. ASUS has corrected garbled Korean text in the warning pop-up and fixed a localization issue that caused the “GPU Clock” and “GPU Voltage” labels for AMD graphics cards to appear in English regardless of the selected language.
Availability and practical considerations
GPU Tweak III 2.1.9.5 is intended for owners of compatible ASUS graphics cards who want more control over connector-current protection. Users should confirm that their card supports Power Detector+ and understand the configured threshold and timeout behavior before relying on automatic shutdown as a safeguard.
The update is primarily a protection and software-quality release rather than a performance update. It does not indicate a change to GPU power limits themselves, but gives supported ASUS hardware another way to respond to detected overcurrent conditions.
