Features: The use of tinned copper wire ensures excellent electrical performances and stable signal transmission capability. The design of flat wires not only makes extension wires look more concisely, but also effectively avoids the problem of tangledwires. The USB3.0 19PIN comes with a clip buckle, which causes the buckle position to be too large and cannot be plugged into the USB3.0 19PIN socket on a regular mainboard. This adapter cable can solve the problem. Designed for serious gamers and computer enthusiasts who demand high performances and reliability. Note: Handmade DIY cutting with wide thread buckle, the appearance of the edges is not very beautiful, please pay attention.
