BUCIER USB 3.0 19/20 Pin Male to 20-pin Female Extender 15 cm

Internal USB 3.0 header extender

This 15 cm flat cable bridges a 19/20-pin chassis connector to a motherboard USB 3.0 header when a graphics card blocks direct access. The male-to-female layout lets you route the slim ribbon around tight clearances without stressing the board socket. Rated for 5 Gbps throughput, it maintains full USB 3.0 signalling across the extension. The 26 AWG copper conductors are encased in a black injection-moulded ribbon that resists kinking and heat buildup.

Builders with cramped GPU clearance

The extender suits anyone whose long graphics card covers the front-panel USB 3.0 header on the motherboard. It also helps when the stock chassis cable is too short or too stiff to reach a relocated header. Systems that already have an unobstructed header or that use a newer internal USB-C header will not need this adapter.

Sustained signal integrity

The flat-ribbon geometry keeps differential pairs parallel, reducing crosstalk during prolonged high-speed transfers. Copper conductors and the moulded strain relief prevent intermittent disconnects caused by vibration or thermal cycling inside a closed case. No active circuitry is present, so latency and power delivery remain identical to a direct header connection.
