This adapter cable allows you to connect any PCI-E device to a Mini PCIe slot through a standard PCI-E 1X / 4X / 8X / 16X port. It is designed for debugging, testing, and extending PCI Express functionality from a Mini PCIe slot. Supports both Half-Mini and Full-Mini PCIe cards. Provides 12V power via a 4-pin FDD power connector for standard PCI-E devices. If your device does not require 12V power, the power cable may be left unconnected. Compatible with PCI Express 1X, 4X, 8X, and 16X cards due to the edge-free/multi-lane design of the PCI-E 1X connector. Features high-quality wiring and connectors, supporting stable PCI-E 3.0 data transfer. No drivers required. Compatible with Windows XP, Windows Vista (32/64-bit), Windows 7, Windows 8, Windows 10, Windows 11, and Linux. Designed for use with PCI Express-based MiniCard slots. If the host’s MiniCard slot does not support the PCI-E interface, this adapter will not function. Performance at PCIe 2.0 (5 Gbps) or PCIe 3.0 (10 Gbps) speeds is not guaranteed and depends on system compatibility. Suitable for engineering applications, PCI-E testing, and extension purposes.
