MSI Afterburner 4.6.7 Beta 2: Enhanced GPU and PSU Monitoring for Next-Gen Graphics Cards
MSI has unveiled Afterburner 4.6.7 Beta 2, a significant update that brings advanced support for the upcoming GeForce RTX 5090 Lightning series and introduces robust power supply unit (PSU) protection features. This release is particularly notable for its integration with MSI’s GPU Safeguard+ system, designed to enhance hardware safety and monitoring for high-performance gaming PCs.
Advanced PSU Integration and GPU Safeguard+
The highlight of Afterburner 4.6.7 Beta 2 is its deep integration with select MSI MEG Ai1x00 and MPG Ai1x00TS power supplies. Through a new PSU.dll plugin, users can now access real-time telemetry data directly within Afterburner. This includes detailed monitoring of voltage, current, power output, temperature, efficiency, and fan speed. For supported MPG units, the software also provides per-pin current data for 16-pin (12VHPWR / 12V-2×6) connectors, a critical feature for users running the latest high-wattage GPUs.
In the event of overcurrent or current imbalance on the 16-pin connector, Afterburner automatically reduces the GPU power limit—typically to 75% for NVIDIA GPUs and 25% for AMD GPUs—and displays an on-screen warning. This proactive approach allows users to inspect and address potential cable connection issues before they escalate. Additionally, sound alerts can be enabled for immediate notification of any detected faults.
Improved Voltage/Frequency Curve Editor
Afterburner 4.6.7 Beta 2 introduces several enhancements to the Voltage/Frequency (V/F) curve editor, making GPU tuning more intuitive and precise. Users can now:
- Adjust the default size of V/F nodes for better visibility.
- Zoom the curve editor window from 100% to 500% using the mouse wheel, with node sizes scaling accordingly.
- Pan the work area by dragging with the right mouse button.
- Reset zoom and pan positions with a keyboard shortcut.
- Utilize improved linear interpolation and arbitrary interpolation modes for more flexible curve adjustments.
- Move V/F curves while preserving per-point offsets, now applicable to selected nodes.
These updates provide both novice and experienced users with greater control over GPU performance tuning, ensuring optimal balance between power, efficiency, and thermal output.
Comprehensive Monitoring and Automated Protection
The new PSU.dll plugin extends Afterburner’s monitoring capabilities to include traditional PSU metrics—such as 12V, 5V, and 3.3V voltages, currents, output power, and efficiency—alongside temperature and fan speed. For the latest MSI MPG Ai1x00TS power supplies, the plugin offers per-pin current monitoring for 12VHPWR/12V-2x6 connectors, with built-in alarm sensors to detect overcurrent or current imbalance conditions.
When a critical threshold is reached, the system can trigger a range of automated responses, including sound alarms, on-screen notifications, emergency profile loading with reduced GPU power limits, or even system shutdown. The new “Enable GPU Safeguard+” option streamlines the configuration of these protective features, making it accessible for beginners while still offering advanced customization for power users.
Additional Features and Improvements
- Support for MSI RTX 5090 Lightning graphics cards ahead of their official launch.
- Command line switches for loading emergency profiles and displaying custom messages during profile application.
- Enhanced monitoring plugins with customizable string names for enum values and simplified critical threshold settings.
- Streamlined alarm configuration for 12VHPWR/12V-2x6 connectors, allowing users to monitor overall safety with a single sensor.
With these updates, MSI Afterburner 4.6.7 Beta 2 sets a new standard for GPU and PSU monitoring, offering both advanced protection and user-friendly controls for enthusiasts and professionals alike. The integration of real-time telemetry and automated safety actions ensures that high-performance systems remain stable and secure, even under demanding workloads.
