This 2×8Pin to 12Pin GPU power adapter cable is used to convert two standard PCIE 8pin power outputs from your power supply to the 12pin proprietary power port on RTX30 series graphics cards. It is perfectly compatible with RTX 3060Ti, 3070 and 3080 video cards. Highconductivity wire cores guarantee stable current supply under highload gaming and rendering conditions, avoiding voltage drop risks. The cable features moderate length for easy routing inside computer chassis, helping you organize internal wiring neatly. No extra driver or modification is required, simply plug both 8pin ends into PSU PCIE ports and connect the 12pin terminal to your graphics card. Important reminder: Please use genuine power supply PCIE 8pin cables instead of splitter cables to prevent insufficient power supply. Perfect for PC building, hardware upgrade and lost original adapter replacement.
