New PSU Tech Fights Melting Graphics Card Cables
7 Jan
Summary
- Cooler Master's GPU Shield protects against melting or fire from power-related cable damage.
- The GPU Shield integrates power protection directly into specific MWE Gold V4 PSUs.
- It monitors current in real-time, alerting users and potentially intervening to prevent meltdowns.
Cooler Master has unveiled its GPU Shield technology at CES 2026, offering an integrated solution to address power-related cable damage concerns, including melting and fire incidents, often linked to high-performance graphics cards. This innovative system is designed to provide real-time power protection directly within the power supply unit (PSU), enhancing the safety and reliability of PC ecosystems.
The GPU Shield will be available on Cooler Master's MWE Gold V4 PSUs, with models ranging from 750W to 1,000W. An adapter version will also be offered, designed to sit between the GPU and the PSU to prevent 12V-2x6 cable meltdowns. This system features detection LEDs to confirm correct cable insertion and monitors the current flowing through the 12V-2x6 connector in real-time.
When an imbalanced load is detected, the GPU Shield issues a warning and may intervene by adjusting power output to prevent overheating and potential damage. While this adds to cable management complexity, it offers a crucial layer of protection for expensive graphics cards, complementing other industry efforts to improve power delivery safety.
