Two-Pack USB 3.0 Header Adapter

This two-pack converts a motherboard USB 3.0 19-pin header to a USB 3.1 Type-E front-panel port. Builders adding a Type-C front-panel connector to a case with only a 19-pin header use these adapters. Each unit measures 2.5cm by 2.4cm by 1cm and weighs 14 grams. The PH73S variant has a straight 180-degree orientation.

5Gbps Limit and Power Constraints

The adapter passes USB 3.0 Gen1 signals only, so throughput stays at 5Gbps; it does not convert the link to 10Gbps. Power is drawn from the 19-pin header at 4.5W (0.9A at 5V), not the 100W available on some newer headers. It is not compatible with USB 2.0 IDC connectors, and high-draw devices such as Pro tablets should not be charged through this port.

PCI-Bracket Mount and Pin Safety

The adapter mounts to a PCI bracket for a secure front-panel installation. Installation requires removing the power cable and waiting 20 seconds before handling to avoid shorting pins. Three orientation types exist — up-90, down-90, and this straight 180-degree PH73S — so verifying the bracket clearance before purchase prevents fitment issues.

Questions about this item

Should I pick the PH73S straight version or a 90-degree variant for my case?

This pack contains the PH73S 180-degree straight adapter; if your PCI bracket clearance needs an up or down 90-degree bend, choose the PH73A or PH73B version instead.

What real-world throughput will I see from the 5 GBit/s header once the adapter is installed?

The adapter passes the motherboard's USB 3.0 Gen 1 signals unchanged, so connected Type-C devices run at 5 Gbps — the same speed as the original 19-pin header.

Does the USB 3.1 Type-E connector on this adapter support the 10 Gbps USB 3.1 Gen 2 standard?

No; the 19-pin header only carries Gen 1 signals, so the Type-E port is limited to 5 Gbps and cannot deliver USB 3.1 Gen 2 speeds.
