* Larger Guage (AWG) wire means higher electricity current carry capacity. 13 amps of power for 18 AWG vs 10 amps for 18 AWG * 18 awg pcie cables carry up to 468 watts at 12 Volts vs standard 18 awg pcie cables that carry up to 288 watts. * Compatible with 6-pin & 8-pin graphics cards from popular manufacturers such as: ASUS, ASRock, EVGA, Gigabyte, Radeon, Sapphire, NVIDIA Tesla GPU, etc. (The 8 pin (6+2) ends could be used as 6 pin or 8 pin end by sliding on/off the 2 pin.) * Length: 12-inch(30.5cm), Gauge: UL1007-18AWG(standard tin-coating copper wire) * Note: This is a GPU 8 pin to GPU 8 pin splitter cable (GPU to GPU), not a CPU 8 pin to 2 X PCIe 8 cable (CPU to GPU) * 2x 6 + 2 pin PCIe Male One Port is a GPU 8 pin for connecting to a modular power supply. The other port is a dual PCI-E 8-pin (6P + 2P) for connecting to a video card
