This desktop PC rear panel USB expansion bracket is specifically designed to solve the problem of insufficient external USB ports on computers, making it especially suitable for home or office
scenarios where multiple peripherals need to be connected simultaneously. It can cleverly route the front-panel USB 2.0 header on the motherboard to the back of the PC case, easily expanding
two USB 2.0 ports. No additional drivers need to be installed, and it supports plug-and-play, so there is no threshold for getting started.
​ The bracket is made of stainless steel, featuring a sturdy and durable structure that is not easy to deform or damage with long-term use. At the same time, it follows the standard PCI slot
bracket design. During installation, you only need to follow the conventional expansion card fixing method, without complex tools, allowing even computer beginners to complete the installation
quickly. In terms of connection design, it is equipped with a 2.54mm pitch 9-pin connector that can accurately connect to the front-panel USB 2.0 header on the motherboard. Moreover,
the connector has a built-in foolproof notch—incorrect insertion methods cannot be completed smoothly, effectively avoiding device failures caused by installation mistakes.​
In addition, the product is equipped with a 30cm-long beige lead wire, which includes two sets of dedicated 4-wire USB cables. The moderate length and clear color facilitate flexible
wiring inside the PC case, adapting to chassis spaces of different sizes and preventing messy wires from affecting internal heat dissipation. It should be noted that this expansion
bracket is only suitable for expanding the front-panel USB 2.0 header of the motherboard; it cannot be used if the motherboard is already connected to front-panel USB devices. Furthermore,
it is only compatible with USB 2.0 and lower specifications (e.g., USB 1.1) and does not have an interface conversion function. The type of the expanded port is consistent with the original
interface type of the motherboard, so you need to confirm the motherboard interface specifications when purchasing.​
