- Cooler Master released the GPU Guard adapter in China.
- The device protects graphics card connectors from overheating.
- Price – 359 yuan (≈ 50 USD), 3-year warranty in China.
- Compatible with 12V-2×6 and 12V HPWR connectors.
A new model from Cooler Master has appeared in the Chinese online store JD.com – the GPU Guard adapter, aimed at protecting graphics card power connectors. The product is positioned as a simple solution to avoid problems related to overheating contacts.
Device and operating principle
GPU Guard is an extender that is installed between the power supply cable and the 12+4-pin connector of the graphics card. Inside the adapter, there are voltage control circuits for 12 V and automatic shutdown functions when anomalies are detected. This approach makes it more accessible than complex protection systems that require additional installation.
Technical Specifications
The package includes a protective case, a 12 V-2×6 cable, a mounting plate, and instructions. The adapter is equipped with an audible alarm and LED indicators that inform the user of an overload. Additionally, the circuit includes a fuse that can break the power supply in case of a critical failure.
The price in the Chinese market is 359 yuan, which is equivalent to about 50 US dollars. At the time of publication, the product is marked as temporarily out of stock, but the company's official channels promise a resumption of supplies.
Cooler Master provides a three-year warranty on the GPU Guard exclusively in China. Under the warranty conditions, the company commits to fully compensate for the replacement of the graphics card if its power connector melts due to the use of the adapter. The warranty does not extend to other countries where the product is not yet available.
According to the manufacturer, the adapter is compatible with all graphics cards equipped with 12V-2×6 and 12V HPWR connectors, regardless of the power supply brand. This makes it a universal solution for a wide range of modern gaming and professional systems.
The issue of overheating power connectors has become particularly relevant with the emergence of high-power graphics cards, where the load on the contacts can reach several hundred watts. Cases of melting connectors are reported in various reviews and forums, leading to costly repairs or complete equipment replacement. GPU Guard is designed to reduce the risk of such incidents by providing users with a simple way to monitor and protect.
So far, the company has not announced plans to launch the product outside of China, but interest in such solutions is growing as more users seek ways to protect expensive graphics cards from damage related to power overload.
