This M.2 extension cable converts onboard 2280 M.2 PCIe Slot (Key M) to PCIe X4 slot and extends to 23.6inch away, so you will get a brand new PCIe X4 port | Work with all PC Peripheral PCIe X1 or PCIe X4 Adapters, such as PCIe Wifi Card, M.2 PCIe Card, Firewire Card, USB PCIe Card, Sound Card, etc. To be noted: although converting to PCIe X4 slot, speed bandwidth is PCIe 3.0 X1 at max | PCIe 3.0 X1 ( about 1000 MB/s) speed bandwidth is guaranteed, just like onboard slots. | To be noted: The maximum speed of the WiFi 6E wireless card is 5400Mb/s=675MB/s, so this PCIe 3.0 X1 ( about 1000MB/s) speed cable will not limit WiFi 6E speed. But for M.2 PCIe 3.0 X4 SSD, the speed will downgrade to PCIe 3.0 X1 speed. | Operating Voltage: 12 Voltage; Output Power: 10W at max. If the power supply is insufficient, the LED will flash. Please connect the 15PIN SATA power cable of the computer, the maximum output power will reach 30W | If after installation, the computer freezes or blue screen. Please re-plug the Mini PCIe extension cable and make sure all devices are well secured. You may need to reinstall the driver for the PCIe adapters | If other PCIe slots cannot be used after using this Mini PCIe extension cable, it may be caused by sharing PCIe Bus between these PCIe lanes. Please check the motherboard technical specification for PCIe Bus Allocation | Easy installation and no extra driver. Plug and Play, and compatible with Windows/Mac OS/Linux/NAS.
