MSI has rolled out the beta version 4.6.7 of its popular Afterburner utility, introducing significant enhancements to GPU protection and expanding hardware compatibility. This update focuses on improved safety features, particularly for high-power connectors, and refines the user experience for overclocking enthusiasts.
Key Takeaways
- Support for MSI’s upcoming GeForce RTX 5090 LIGHTNING series.
- Introduction of GPU Safeguard+ for enhanced 12V-2×6 power connector monitoring and protection.
- Integration with new MSI MPG AI1x00TS power supplies for detailed telemetry.
- Improvements to the Voltage/Frequency (V/F) curve editor for better usability.
- New command-line options for automated emergency profiles and custom notifications.
Enhanced GPU Safeguard+ Features
The most notable addition in MSI Afterburner 4.6.7 Beta 2 is the integration of GPU Safeguard+, a PSU-side protection system. This feature monitors the dual 12V-2×6 power delivery, providing real-time alerts for abnormal behavior. A new PSU.dll monitoring plugin exposes telemetry from supported MSI MEG Ai1x00 and MPG Ai1x00TS power supplies.
This plugin offers traditional PSU monitoring (voltage, current, power, temperature, efficiency, fan speed) and, crucially for the MPG models, per-pin current data for 12VHPWR and 12V-2×6 connectors. The safeguard logic uses this data to detect faults. Users can enable a simplified “Enable GPU Safeguard+” option, which triggers sound alerts and initiates an emergency mitigation flow when an alarm is tripped. This flow can automatically load a predefined profile with reduced GPU power consumption or display a custom on-screen message, helping users quickly address potential connection issues.
Voltage/Frequency Curve Editor Improvements
For users who frequently tune their hardware, the Voltage/Frequency (V/F) curve editor has received several usability enhancements. These include adjustable V/F node sizes via a configuration file, the ability to zoom the work area from 100% to 500% using the mouse wheel, and panning capabilities with the right mouse button. Keyboard shortcuts are available to restore the default view. Additionally, the editor now features improved linear voltage curve interpolation modes, including a fixed anchor point and an arbitrary linear interpolation mode for more precise curve adjustments.
Broader Hardware Support and New Functionality
Beyond the RTX 5090 LIGHTNING series, Afterburner 4.6.7 Beta 2 introduces support for new MSI MPG AI1x00TS power supplies, enabling detailed monitoring of their 12VHPWR/12V-2×6 connectors. The update also includes new command-line switches for loading predefined emergency profiles with lowered GPU power limits (75% for NVIDIA, -25% for AMD) and for displaying custom text messages when a profile is applied. Monitoring plugins can now also specify string names for enum values, improving the clarity of on-screen display data.
