  • ColorBlack
  • Connect USB 3.0 front-panel devices to USB 2.0 motherboard headers
  • 12 cm cable keeps internal routing tidy
  • 19-pin and 20-pin male plugs fit common USB 3.0 headers
  • 9-pin and 10-pin female sockets accept standard USB 2.0 headers
  • 480 Mbps throughput for connected USB 3.0 devices

USB 3.0 front-panel adapter for legacy headers

This 12 cm cable converts a 19- or 20-pin USB 3.0 front-panel connector to a 9- or 10-pin USB 2.0 motherboard header. It suits builders who have a modern case but an older board lacking a native USB 3.0 header. Data runs at 480 Mbps, matching USB 2.0 throughput. The compact length keeps routing tidy inside small chassis.

Fits between case front panel and motherboard header

The male end plugs into the case’s USB 3.0 front-panel cable while the female end seats on the board’s 9- or 10-pin USB 2.0 header. No extra power or drivers are required. The adapter frees the USB 3.0 front ports for use even when the motherboard lacks a 19- or 20-pin header. Cable management stays simple thanks to the short 12 cm reach.

Handles USB 2.0 speeds on USB 3.0 ports

Connected devices operate at up to 480 Mbps, the full USB 2.0 rate, so keyboards, mice and flash drives work normally. The link does not deliver USB 3.0’s 5 Gbps bandwidth, so high-speed external SSDs will run slower than their rated potential. Builders needing full SuperSpeed throughput must use a board with a native 19- or 20-pin header instead.

Questions about this item

Does the 480 Mbps ceiling throttle a USB 3.0 front-panel device during long transfers?

The adapter converts the 19/20-pin header to a 9/10-pin motherboard connector, so the link runs at USB 2.0 speeds — 480 Mbps is the hard limit.

Will the 12 cm cable add noticeable heat or noise inside a case running all day?

No active components are present; the short passive cable draws negligible power and produces no audible noise or measurable heat.

Must the motherboard already have a 9-pin or 10-pin USB 2.0 header for this to work?

Yes, the female end plugs into a standard 9-pin or 10-pin USB 2.0 motherboard header; without one the adapter cannot connect.
