Cable features high-quality PCIe connectors with support for PCIe 3.0 8G/s stable transmission. BIOS speed adjustment is not required. The core wire includes power supply lines, allowing use with mining motherboards without an external power source, enabling direct connection to graphics cards. Adapter cables have low cable impedance. Differential signal design eliminates vias, preventing signal attenuation and interference from parasitic capacitance and inductance, and avoids CAF micro-short circuit issues. PCB is made from high-quality, high-frequency, low-resistance materials with precision manufacturing, using high-grade boards and thickened 1oz copper. Gold-plated fingers feature 10u plating, matching the quality level of graphics card connectors. Gold-plated contacts provide excellent electrical conductivity, improving resistance to oxidation and corrosion, helping reduce system crashes or blue screens. Thick copper layers support high power demands of mining-grade graphics cards.
