  • Adds two USB 3.0 Type-A ports from a single 20-pin header
  • Delivers 5 Gbps data throughput for fast file transfers
  • Works with USB 2.0 and 1.1 devices for broad compatibility
  • Installs without drivers — plug straight into the motherboard
  • Compact design leaves space for other internal connectors

Dual 20-pin USB 3.0 adapter

This adapter converts a single motherboard 20-pin USB 3.0 header into two external USB 3.0 Type-A ports. It is intended for PC builders or upgraders who need extra front-panel or internal USB connections without occupying expansion slots. The device works with standard 19-pin and 20-pin headers found on modern mainboards.

Plug-and-play header conversion

No driver installation is required; the adapter operates immediately once seated on the header. Its compact footprint leaves clearance for neighbouring connectors on crowded boards. Backward compatibility with USB 1.1 and 2.0 ensures older peripherals still function at their rated speeds.

5 Gbps throughput per port

Each female port supports the USB 3.0 maximum of 5 Gbps, sufficient for external SSDs, high-capacity flash drives or docking stations. The shared header bandwidth becomes the limiting factor when both ports transfer large files simultaneously. Builders needing more than two additional ports or independent controller bandwidth will require a separate add-in card.

Questions about this item

Will the 20-pin header connector wear out if I plug and unplug devices daily?

The adapter uses a passive 20-pin header with no moving parts; normal daily insertion of USB 3.0 devices will not degrade the motherboard socket.

What limits sustained throughput when I run both USB 3.0 ports at 5Gbps?

Total bandwidth is shared across the single 20-pin header, so simultaneous transfers on both ports divide the 5Gbps link.

Does the adapter get hot or draw extra power when both ports run all day?

No active circuitry is present, so heat and power draw stay negligible even with continuous dual-port operation.
