EXSYS EX-12002-2 PCIe x4 na 2-port USB 3.2 Gen 2 Type-A host kontrolér karta

The EXSYS EX-12002-2 stands out from typical USB expansion cards by combining a PCIe x4 interface with the ASMedia ASM3142 chipset, delivering two true 10 Gbit/s USB 3.2 Gen 2 Type-A ports without sharing bandwidth. Unlike budget cards that bottleneck on a single PCIe lane, this controller uses four PCIe lanes to ensure both ports can operate at full speed simultaneously, making it ideal for high-throughput devices like external SSDs, VR headsets, and 4K capture cards.

Highlights

• Two independent USB 3.2 Gen 2 Type-A ports, each capable of 10 Gbit/s
• PCIe x4 host interface for sustained high-speed data transfers
• ASMedia ASM3142 controller with UASP support for reduced CPU overhead
• Backward compatible with USB 3.0, 2.0, and 1.1 devices
• Includes both standard and low-profile brackets for versatile installation

In daily use

Installing the EX-12002-2 is straightforward: insert the card into any available PCIe x4, x8, or x16 slot, secure it with the appropriate bracket, and load the drivers for your operating system. The card draws power directly from the PCIe bus, but an optional SATA 15-pin power connector is provided for stable operation when connecting power-hungry devices. Hot-swap support allows you to connect and disconnect USB peripherals without rebooting your system, and the UASP protocol accelerates transfers with modern storage devices. Whether you are upgrading a workstation for fast external backups or adding high-speed ports to a server, this card delivers consistent performance.
