SKU CH-GS7M-MXAS7

  • Converts one internal header into two external USB ports
  • 30cm cable keeps internal routing tidy
  • 120mm PCIE bracket secures ports to chassis back panel
  • USB 2.0 delivers 480Mbps data and power to peripherals
  • Supports mice, keyboards, flash drives and other USB-A devices

USB 2.0 header expansion for desktop builds

This 30 centimetre cable converts one motherboard USB 2.0 9-pin front-panel header into two external USB 2.0 female ports. A 120 millimetre PCIe slot bracket secures the ports to the chassis back panel. The short length keeps internal routing tidy in custom desktop builds.

USB 2.0 bandwidth and power limits

The connection runs at USB 2.0 speeds with a maximum data rate of 480 megabits per second. Both ports share the single header's power budget, so high-draw devices may not operate simultaneously. The cable does not upgrade the interface to a faster standard.

Check header availability and bracket clearance

Verify the motherboard has a free USB 2.0 9-pin front-panel header before ordering. Ensure the case has an open PCIe slot bracket position with at least 120 millimetres of width for the mounting plate. Confirm the 30 centimetre cable reaches from the header to the chosen slot.

Questions about this item

Should I pick the 30cm cable or a longer one for a standard ATX case?

The 30cm length is designed for neat internal routing from a motherboard USB 2.0 9pin header to a rear PCIe bracket; measure your board-to-slot distance to confirm reach.

What does the 480Mbps figure mean when I plug in a flash drive?

480Mbps is the USB 2.0 signalling rate; actual file-transfer speed will be lower due to protocol overhead and the drive’s own limits.

The bracket is 120mm — does that fit any PCIe slot opening?

The 120mm bracket matches a standard full-height PCIe slot cut-out, letting you mount the two USB 2.0 female ports securely on the chassis back panel.
