PCI-Express 3.0 x16 riser cable (300mm Length, Male to Female 90 Degree Angle) for GPU and PCIe host adapter. Backward compatible with PCIe 2.0/PCIe 1.0 | Ribbon cable length = 300 mm (not including the PCIe ports). Before purchasing, be sure to measure the needed length of the PCIe extension cable based on the placement of the graphics card in the chassis. | 90 Degree Angle at female side for GPU vertically mounting to PC chassis. Please ensure that the back panel of the chassis has vertical fixing slots for GPU vertically installation | Full compatible with gen 3.0 GPU, such as GTX1080, GTX1080Ti, RTX2060, RTX2070, RTX2080, RTX2080Ti, RX570, RX580, RX590, RX5700 XT, RX VEGA 56, RX VEGA 64 etc. | For gen 4.0 GPU, please change the motherboard PCIe slot to Gen 3.0 mode in BIOS first. Otherwise there may be incompatibility. | EMI shielded design ensures signal integrity and full speed performance. | The female port has multiple oval holes for easy attachment to the base. (Base not included) | Several separate ribbon cable design make it softer and more flexible. When the GPU mounting position is shifted a bit, it doesn't affect the performance.
