GIGABYTE GC-USB 3.2 Gen 2x2 PCIe Expansion Card

SKU CH-BGF4-YYXXM

Adds a USB Type-C port with 20 Gbps transfer speed and backward compatibility with USB 2.0, 3.0 and 3.1 via a PCIe x4 slot

  • 20 Gbps data transfer via USB 3.2 Gen 2x2
  • Adds USB Type-C port through a PCIe x4 slot
  • Backward compatible with USB 2.0, 3.0 and 3.1 devices
  • Upgrade to 20 Gbps speeds without replacing the motherboard
  • Flexible, cost-effective expansion for existing systems

USB 3.2 Gen 2x2 PCIe Expansion Card

The GIGABYTE GC-USB 3.2 Gen 2x2 PCIe Expansion Card adds a single USB Type-C port supporting 20 Gbps transfer speeds to desktop systems. It installs into an available PCIe x4 slot to provide the latest USB 3.2 Gen 2x2 connectivity. This card targets users who need faster external storage or peripheral performance without replacing their motherboard. It is not for buyers who require multiple high-speed ports or internal header connections.

Passive cooling and bus power

The expansion card operates without a dedicated fan, relying on passive heatsink cooling and airflow inside the chassis. Power is drawn directly from the PCIe slot, so no external power connector is required. Under normal use the card runs silently and adds minimal load to the system power budget. Builders with severely restricted airflow or fully occupied power budgets should verify their specific constraints.

Single USB Type-C port at 20 Gbps

The card provides exactly one USB Type-C port running at the USB 3.2 Gen 2x2 20 Gbps rate. It maintains backward compatibility with USB 2.0, 3.0 and 3.1 devices connected through suitable cables or adapters. This single-port design suits users adding one high-speed drive or dock; it does not serve builds needing several simultaneous 20 Gbps connections.

Questions about this item

How do I install the GC-USB 3.2 Gen 2x2 card in a PCIe x4 slot?

Power down the PC, open the case, remove the bracket for a free PCIe x4 slot, press the card firmly into the slot until it clicks, secure it with the case screw, then boot and let the OS load the USB 3.2 drivers.

What maintenance or replacement will the GC-USB 3.2 Gen 2x2 card need over time?

No scheduled maintenance is required; keep the USB Type-C port free of dust and debris, and replace the card only if the port becomes physically damaged or the controller fails.

What is the first limit I will hit under sustained 20Gbps transfers on the GC-USB 3.2 Gen 2x2 card?

The PCIe x4 host link and the USB 3.2 Gen 2x2 controller both cap throughput at 20Gbps, so sustained transfers cannot exceed that ceiling.
