1.PCIE 8P - Dual 8P (6 + 2): Connects to PSU with an 8-pin connector , and to the GPU with 8-pin (6+2) connectors. (It can be split into 6-Pin or combined into 8-Pin for use, compatible with different graphics card interfaces.)Note: These connectors are not interchangeable. 2.GPU-Specific Power Delivery: Compatible with 6-pin and 8-pin GPU interfaces across major brands, supporting all models from 2015 onward (including NVIDIA GeForce RTX/GTX series, AMD Radeon RX series).Including GTX1080, GTX1080Ti, RTX2060, RTX2070, RTX2080, RTX2080Ti, RTX3060, RTX3070, RTX3080, RTX3090, RX570, RX580, RX590, RX5700 XT, RX6700 XT, RX6800 XT, RX6900 XT. 3.Compatibility: Fits EVGA Super Nova PSU models: G+ 650、750、850、1000、1300、1600、2000 GA 550、650、750、850 G2 550、650、750、850、1000、1300、1600 G3 550、650、750、850、1000 G5 650、750、850、1000 G6 650、750、850、1000 GM 450、550、650、750、850 GT 650、750、850、1000 P+ 1300、1600 P2 650、750、850、1000、1200、1600 P3 1000、1200 P5 650、750、850、1000 P6 650、750、850、1000 T2 850、1000、1200、1600 4.Features: Length 63 (including connector), Gauge: 1007-18AWG (standard tin-coated copper wire). Not suitable for high-power GPUs or motherboards. 5.Graphics Card Side: The 6+2 Pin can adapt to the 6-Pin or 8-Pin interfaces of graphics cards. When combined and inserted into an 8-Pin port, ensure the buckle is fixed. Power Supply Side: Must be inserted into the 8-Pin modular port labeled "PCIe" or "VGA" on the power supply. Do not mistakenly insert it into the CPU 8-Pin port, as the pin definitions of the two are different. 6.Critical Note: This PCIe cable is only compatible with specified PSU models. Before ordering, please verify your power supply brand, model, and modular connector compatibility. Contact us for technical support if needed.
