USB 3.0 Y splitter for motherboard headers
This SXDOOL adapter converts a single 19-pin motherboard header into two 20-pin USB 3.0 ports using a 12 cm flat cable. It is designed for builders who need to connect two front-panel USB 3.0 connectors while only one internal header is available on the board.
Signal integrity on a short flat cable
The 12 cm length keeps trace resistance low, so sustained USB 3.0 data transfers stay within specification without the voltage drop seen on longer ribbon cables. The flat construction resists tangling inside tight chassis, and the 38 g weight adds negligible strain to the motherboard header during prolonged use.
Check header pin-out and chassis clearance
Verify that your motherboard provides a standard 19-pin USB 3.0 header before ordering, because pin assignments differ between vendors. Ensure the 12 cm reach matches the distance from the header to your front-panel ports, and confirm the flat cable can be routed without sharp bends that could damage conductors.

Questions about this item
Does the 12 cm cable add noticeable heat or power draw when the connected USB 3.0 devices run all day?
The passive splitter draws no power itself; only the attached USB 3.0 devices consume current, and the short 12 cm length adds negligible resistance.
What must my motherboard already provide for this Y splitter to work?
A single USB 3.0 19-pin header supplies both 20-pin ports on the splitter.
Will the 19-pin connector fit older motherboards that only have USB 2.0 9-pin headers?
No, the 19-pin plug is keyed for USB 3.0 headers and will not mate with a 9-pin USB 2.0 header.
