1. Cable advantage, using high-quality PCIe connectors, high-frequency support for PCIe 3.0 8G or stable transmission. The BIOS does not need to adjust the speed, the core wire contains the power supply, and the extension cable of the mining motherboard can be used without an external power supply, and the graphics card can be used directly. 2. The adapter cables have low cable impedance. 3. The differential signal has no via design, there is no signal attenuation interference problem of parasitic capacitance and parasitic inductance, and there is no CAF micro-short circuit phenomenon. 4. The PCB is made of high-quality materials with high frequency and low resistance. The PCB is made of precision, and the PCB uses high plates and copper. The thickness of the material is thickened to 1oz. The content of 10u gold-plated gold finger is the same level as that of the graphics card. 5. The gold-plated foot has good electrical conductivity and can reduce the blue screen of crash caused by the increase of oxidation and rust resistance. The thick copper thickness can meet the PCIe high power consumption problem of mining graphics cards. The product is .
