Product use: In order to save costs, the current power supply of the computer is suitable for the power port without 8PIN video card, or when the power port is not enough when using multiple graphics cards for mining or mining. The conversion cable can solve the problem and directly convert the dual SATA 15PIN power supply to the 8PIN power port of the video card, which increases the current of the graphics card. Because high-end graphics cards all use 8PIN power supply, the current is relatively large, with a single SATA port current is not enough, easy to burn. So you need to use 2 SATA ports to provide 12V video 8PIN power supply. Application use: SATA power supply is connected to the host computer SATA power supply, 8Pin graphics 8PIN.
