Down-90° USB 3.0 header adapter

This two-pack provides a Down-90 degree PH73B adapter that converts a motherboard USB 3.0 19/20-pin header into a USB 3.1 Type-E front-panel port. It is aimed at builders adding a Type-C front-panel cut-out or PCI bracket without rewiring the internal header. The adapter carries only USB 3.0 Gen1 signals so the link remains at 5 Gbps.

Compatibility checks before ordering

Verify the motherboard header is a 19/20-pin USB 3.0 IDC connector; the adapter will not fit a USB 2.0 header. Confirm the chassis cut-out or bracket suits a Down-90 degree orientation, as Up-90 and 180 degree variants exist. Ensure system power is removed and wait 20 seconds before installation to avoid pin shorting.

What the bundle changes

Two identical adapters let you equip two front-panel Type-C ports or keep a spare for a second build. No driver installation is required across Windows XP through 10, macOS and Linux. The plastic-and-metal housing measures 2.5 cm by 2.4 cm by 1 cm and weighs 16 grams total.

Questions about this item

What connectors are on the PH73B adapter and what extra parts are needed for installation?

Each adapter has a Down-90 degree USB 3.0 19/20-pin female socket on one side and a 90 degree USB 3.1 Type-E female header on the other. Mounting to a PCI bracket is required; screws or a bracket are not included.

Which PH73 variant should I choose for my motherboard header orientation?

Choose PH73B when the 19/20-pin header points downward and you need the Type-E port angled down at 90 degrees. PH73A angles upward and PH73S is a straight 180 degree version.

What real-world transfer rate will I get through the Type-E port on a USB 3.0 header?

The header carries only USB 3.0 Gen 1 signals, so the Type-E port is limited to 5 Gbps. The adapter does not convert the link to 10 Gbps.
