Warning: The PCIe riser cable is Gen3 (PCIe 3.0). If you are using a Navi or Ampere GPU along with a B550/X570/Z490/Z590 motherboard, please set your PCIe slot setting from Gen4 (PCIe 4.0) to Gen3 in the BIOS. If you do not change the setting, there is a high risk that you will have video output issues. There’s no need to be concerned about being limited to Gen3, as testing has shown that even with an RTX 3080, there is less than a 5% performance loss downgrading from a Gen4 to Gen3 connection.

显卡延长线速度为Gen 3（PCIe 3.0)， 装机前请在裸机平台带延长线点亮

如遇到显卡无输出情况，请直插显卡进入BIOS将PCIE速度从4.0改为3.0   

PCIE 3.0延长线带宽足够当下主流显卡使用， 不会对显卡性能造成明显影响
