Power supplies for a special protective cable will start shipping soon as Cooler Master begins taking pre-orders.
Cooler Master GPU Shield-Equipped MWE Gold V4 Goes On Pre-Order in China; Just Buy Demonstrates GPU Shield Features
Not just ASRock and ASUS, Cooler Master has also prepared a special 16-pin power cable for RTX GPUs that aims to tackle connector burning. While first introduced at CES this year, the GPU Shield requires compatible power supplies to operate. Cooler Master did announce the MWE Gold V4 series with the built-in GPU Shield, but it hasn't been out yet. However, it appears that the power supply units will soon start hitting the shelves.
As reported by @unikoshardware, the Cooler Master MWE Gold V4 has started appearing on popular retailers such as JD for pre-orders. Currently, the 850W-capacity MWE Gold v4 is available on the platform for 659 Yuan (US$97), and additional capacities are in development, including a 1000W unit. There will be three capacities in the family: 750W, 850W, and 1000W as announced by Cooler Master previously.
The MWE Gold V4 PSUs natively support the GPU Shield, which protects the GPU connector from burning and no additional connectors. The GPU Shield aims to fix the inherent flaw in the 12V-2x6 connector that causes improper load distribution across the wires. According to Cooler Master, the GPU Shield adds real-time electrical monitoring between the PSU and the GPU connector.
Just Buy has demonstrated how it works in a video uploaded on Bilibili. On the MWE Gold V4, there is an LED near the 16-pin connector that indicates the current status of the situation. If the LED is Green, it means the connector is fully seated, and the current distribution is uniform. If it blinks Red, it indicates improper connection and improper current distribution. In case the current distribution is too abnormal, the LED will light up red and the GPU's protection mode will be triggered, resulting in screen blackout.
- Current <9.3 A= Green LED
- Current >9.3 A= Red Blinking LED
- Current >15 A= Continuous Red LED and screen blackout
The GPU Shield Adapter cable will be sold separately as clarified by Cooler Master when the MWE Gold V4 launches and will be compatible with "all" PSU manufacturers. The adapter cable provides the same protection as the MWE Gold V4, but will cost much lower than the PSU itself.
