Upgrade your desktop with the Simplecom EC365 PCIe x4 2-Port USB-C Expansion Card, designed to enhance your system's connectivity for modern peripherals and displays. This expansion card features two USB-C ports: one dedicated to high-speed data transfer (USB 3.2 Gen 2, 10Gbps), and the other supporting DP Alt Mode for simultaneous 4K@60Hz video output and data transfer.

A unique mini DisplayPort (miniDP) input allows video passthrough by connecting to your motherboard or GPU's DisplayPort output. This setup enables seamless video transmission through the USB-C port to compatible docking stations or monitors without requiring a separate graphics processor.

Installing the EC365 is simple — it fits into any PCIe 3.0 x4, x8, or x16 slot and draws power directly from the PCIe slot via a built-in 12V to 5V power module, eliminating the need for external power adapters. The card also includes over-current protection on each USB port to safeguard connected devices.

Compatible with Windows 10 and later, this plug-and-play expansion card is ideal for users looking to add USB-C connectivity with video capabilities to desktop PCs lacking native support.
