This adapter cable allows you to connect any PCI-E device to an M.2 Dual Key A-E slot via a standard PCI-E 4X port. Supports M.2 socket with form factor 2230. Provides 12V power via a 4-pin FDD power connector for standard PCI-E devices. If your device does not require 12V power input, do not connect the included power cable. The PCI Express 4X connector is compatible with 1X, 4X, 8X, and 16X PCI-E cards. The optimal match is 4X; however, data transfer speed is limited to 1X due to M.2 interface bandwidth constraints. Features high-quality wiring and connectors, supporting stable PCI-E 3.0 high-frequency data transfer. No drivers required. Compatible with Windows XP, Vista (32/64-bit), Windows 7, Windows 8, Windows 10, Windows 11, and Linux. System requirement: Motherboard must have an M.2 Key A or Key E slot. Some M.2 slots support PCIe-based WLAN modules (e.g., Intel 9260, AX200), but compatibility is not guaranteed. Modules using CNVi or CNVio2 interfaces (e.g., Intel 9560, AX201) are not supported, as they do not use a standard PCIe Wi-Fi interface. Cable length: approximately 20 cm. Total length: approximately 22.5 cm. Cable thickness: approximately 1.0 mm. Suitable for engineers, PCI-E testing, extension, and related applications. Color: As shown. Material: Plastic.
