This extension cable is not suitable for GPUs with 12pin interface such as RTX3090, but only supports 12+4pin GPUs such as RTX4090, RTX4080, RTX3090ti and 4000 series.16AWG tinned copper wire: The PCI-e 5.0 extension cable contains 16AWG tinned copper wire. Compared with the standard 18AWG power cable, this updated 16AWG tinned copper wire can bring stable transmission and higher power output.Neat: 34cm GPU riser extension cable, compared with 10cm power cable, can make your DIY computer system neat.Up to 600W output: PSU extension cable supports up to 600W output. The plug terminal of the graphics card cable is made of copper and tinned material, which can bring stable and higher current. This extension cable only needs 8 pins to convert to 12+4 pins, which is simple and safe to power the GPU. It is recommended to use a power supply of more than 1000W for better and more stable performance.Note: Do not use the PSU 8-pin to dual 6+2-pin PCIE power cable as two connection ports to avoid power overload problems. We recommend using 4 PCIE power cables for better and more stable performance.Wire comb: random style random color, no designation acceptedColor: blackMaterial: copper Package Contents: 1 x extension cable Only the above package content, not including other products.Note: Light reflection and different monitors may cause the color of the item to be slightly different from the actual object.
