MSI just announced its new GPU Safeguard and GPU Safeguard+ tech available on its latest power supply units (PSUs). According to the company press release, this feature monitors the 12V-2x6 connector for abnormal current fluctuations, and it will then warn the user with a pop-up through the MSI Center (only for GPU Safeguard+) while the PSU itself will emit an audible warning buzzer. “This proactive alert system enables potential power issues to be addressed before they result in permanent hardware damage,” MSI said in its PR.
The Tom’s Hardware team visited the MSI booth at CES 2026, where it was explained that this protection is achieved through per-in-voltage monitoring. And if it indicates an anomaly, the only way you can stop the buzzing is by shutting your computer down, thereby cutting power to the GPU and helping protect it even before its power connector starts melting.
