MSI has introduced innovative 16-pin safety features within its AI PSU range, including the advanced GPU Safeguard+.These enhancements are designed to prevent accidental damage to high-performance graphics cards like the RTX 5090.
MSI’s Innovations: Ensuring the Safety of High-End GPUs on 16-Pin Connectors
Recently, MSI unveiled a significant update for its Afterburner utility, adding support for the future RTX 5090 Lightning Z graphics card alongside its latest AI PSU series. This article will explore the groundbreaking features aimed at protecting your GPU from operational anomalies and potential damage.
Moreover, it’s noteworthy that the new MSI PSU lineup is compatible not only with Afterburner but also with HWINFO. This means that the latest safety algorithms can effectively identify abnormal operations in 16-pin connectors and can reduce power consumption to 75% across all RTX 50 GPUs, not limited to just the RTX 5090 model.
For instance, when an RTX 5090 is in use, which typically operates at a thermal design power (TDP) of 575W, should it detect an irregular connection, the power draw automatically decreases to 75%, or 430W. Additionally, a prompt will appear, advising users to check the cable connections, and if issues persist, recommend replacing the faulty cable.
The latest beta version of HWINFO also provides real-time monitoring of the current flowing through each 12V-2×6 (16-Pin) cable linked to MSI’s MPG and MEG AI PSUs. This monitoring capability extends to abnormal current alerts, mirroring the features available in Afterburner.
Utilizing GPU Safeguard+ for Enhanced Workload Management
- The upgraded Afterburner now integrates MSI’s GPU Safeguard+, which can automatically lower the GPU power limit to 75% when it identifies an imbalance in current on supported models like the MPG Ai1600TS PCIE5 and MPG Ai1300TS PCIE5.
- When an imbalance in the current among the 12V-2×6 pins occurs, GPU Safeguard+ activates to reduce the GPU workload from 100% to 75%.
- Demo videos show how the GPU Power Limit will decrease from around 575W to 430W in response to a malfunctioning 12V-2×6 cable, along with a warning prompt from Afterburner urging users to inspect the connection.
Real-Time Alerts for Current Anomalies
- Afterburner delivers real-time alerts when the current on any individual 12V-2×6 pin strays beyond set thresholds, contributing to a safer computing environment.
- Similarly, HWINFO version 8.41 beta displays real-time data for each pin’s current flow on MSI’s MPG 1600TS/1300TS PCIE5 PSUs, supporting alerts for abnormal currents akin to Afterburner.
A crucial feature included is a built-in buzzer, which will sound for three continuous minutes upon detecting an anomaly. Within both Afterburner and HWINFO, users can configure the alert system to display notifications while adjusting the status of the 12V-2×6 connector, signifying a potential issue.
The GPU Safeguard+ mechanism also features a rigorous response protocol, triggering a black screen after three minutes if the user does not rectify the underlying issue, while the buzzer continues to emit warnings. The comprehensive operational cycle of GPU Safeguard+ functions in the following manner:
This active protection features our latest PSUs consistently monitoring for faults. If they detect high current flow through a pin or dangerous power spikes lasting more than milliseconds, the safety system springs into action.
In response, audible alarms will prompt you to acknowledge the issue; beeps signal Phase 1 of the protection.
Power Supplies equipped with GPU Safeguard+ will alert you through both sound and MSI Center notifications. This beeping continues for three minutes, providing ample time to safeguard your work.
If you are absent when the safety measure is engaged, the system automatically intervenes after three minutes, displaying a black screen and maintaining the audible alerts.
For MAG Power Supplies, the protocol remains the same, compelling users to address the issue by reseating the cable.
Through these enhancements, MSI actively protects one of your computer’s most essential components—its GPU. Given numerous reports of damage caused by inadequate 16-pin connectors, such innovations are a welcome development for PC enthusiasts and gamers alike.
