  • Add two rear USB 3.0 ports from one internal header

  • Driver-free installation works immediately

Dual USB 3.0 back-panel adapter

This cable kit converts a single internal 20-pin USB 3.0 motherboard header into two external USB 3.0 female ports mounted on a supplied bracket. It is intended for PC builders who have a spare onboard header and want additional rear connectivity without occupying an expansion slot. The 50cm cable reaches most chassis rear cutouts. No extra drivers are required.

Header-to-panel pinout match

The decisive specification is the 20-pin USB 3.0 motherboard connector that must match the header on your board. Verify the header pinout and keying before purchase; an incompatible header will prevent the adapter from functioning. The kit provides two standard USB 3.0 Type-A female ports on the bracket side.

Bracket mounting and cable routing

Installation consists of plugging the 20-pin connector into the motherboard header and securing the bracket to a rear case opening with a screw. The 1.5ft cable is short, so the header must be near the bottom or middle of the board; distant headers may not be reached. A common issue is misaligning the keyed header, which can bend pins if forced.
