Simplecom EC312v2 PCIe x4 to 2-Port USB 3.2 Gen II 10Gbps USB-C and USB-A Expansion Card

Turn a PCIe slot into a high‑speed USB hub with the Simplecom EC312v2 PCIe x4 to 2-Port USB 3.2 Gen II expansion card. This compact PCIe add‑in quietly unlocks two dedicated Gen II ports—one USB‑C and one USB‑A—each capable of up to 10 Gbps for fast external storage, video workflows, and seamless data transfers.

Two dedicated, high‑speed ports

The EC312v2 delivers two separate USB 3.2 Gen II channels at 10 Gbps each. You get:

• USB‑C port supporting high‑speed data transfers and modern peripherals.
• USB‑A port offering the same 10 Gbps performance for a wide range of devices.

With both ports available on a single card, you can run demanding drives and docks in parallel without compromising performance on either link.

PCIe‑based, self‑powered design

Built to slot into PCIe 3.0 x4 boards, the EC312v2 also works in x8/x16 slots, making it compatible with a broad range of systems. It is self‑powered through the PCIe bus, using integrated 12V to 5V regulation and overcurrent protection to keep your components safe. No extra power adapters are required, which keeps your build tidy and reduces cable clutter.

Easy installation and broad compatibility

Designed for a smooth, plug‑and‑play experience on Windows, the card auto‑recognizes drivers for broad USB device support. It’s compatible with Windows 7 and newer releases, making it a practical upgrade for existing desktops and workstations. An included mounting bracket simplifies installation in standard PC cases, delivering a clean, professional look in any build.

Why this card matters for your workflow

• External NVMe/SATA drives benefit from sustained dual‑port bandwidth for fast backups, ready access to large libraries, and rapid data migration.
• High‑speed docks and capture devices can run on separate ports, reducing bottlenecks in creative or data‑intensive pipelines.
• Video workflows—edit, render, and offload footage to fast storage without saturating other PCIe lanes.
• Future‑proofing with Gen II 10 Gbps ports ensures compatibility with next‑generation peripherals that demand higher throughputs.
