Front-panel USB 3.0 hub for 3.5" bay

This hub adds four USB 3.0 Type-A ports to the front of a desktop PC by mounting in a standard 3.5-inch floppy bay. It connects to the motherboard through a 20-pin internal header and uses a built-in GL3520 chipset. The device is suited for builders who want convenient front access to high-speed peripherals.

Check motherboard header and power budget

Verify that the motherboard provides a 20-pin USB 3.0 front-panel header before ordering. Each port can deliver up to 900 mA, so confirm the header and power delivery can support the total load of attached devices. The hub complies with USB 3.0, 2.0 and 1.1 specifications for backward compatibility.

Fits 3.5" bay and frees rear ports

Installation occupies one 3.5-inch front bay and routes a single 20-pin cable to the motherboard, leaving rear I/O ports free for other connections. Super-speed 5 Gbps, hi-speed 480 Mbps and low-speed 1.5 Mbps operation are all supported. Buyers needing more than four front ports or a different bay size should consider alternative solutions.

Questions about this item

What comes in the box and do I need a separate motherboard header cable?

The hub installs in a 3.5" floppy bay and includes a 20-pin cable that plugs directly into the motherboard USB 3.0 header; no extra cable is required.

There is only one version listed, so how do I know this is the right capacity for my build?

The single model provides four USB 3.0 Type-A ports driven by a GL3520 chipset, each delivering up to 900 mA, which matches the standard front-panel expansion need.

The spec says 5 Gbps Super-Speed — what throughput will I actually see with a typical external SSD?

The hub is compliant with USB 3.0 at 5 Gbps, USB 2.0 at 480 Mbps and USB 1.1 at 1.5 Mbps; real-world SSD speeds will be limited by the 5 Gbps link and the 900 mA per-port power budget.
