PCIe to M.2 22x60 B+M key card

This card adds a single USB Type-C port running at 10 Gbps to a desktop via a PCI Express 3.0 x2 slot. It accepts M.2 2260 B+M key modules and is aimed at builders who need an extra high-speed USB connection without replacing the motherboard.

Driver and power requirements

No driver is needed for Windows 10, 8, Server 2012 or later, Linux kernel 2.6.31 or later, and macOS 10.9 to 10.10 plus 10.12 onward. Windows 7, Vista, Server 2008 and 2003 require a download. The card draws up to 2 A at 5 V from a Molex power connector which must be attached for the port to function.

Sustained throughput

The ASM3142 controller uses PCIe Gen3 x2 lanes to maintain the 10 Gbps link under continuous load, delivering roughly double the bandwidth of a single-lane design. Performance scales with the attached M.2 device and the host chipset, so very long transfers stay near the rated speed rather than throttling after a short burst.

Questions about this item

How can I confirm the ASM3142 controller is delivering 10 Gbps after installation?

Connect a USB 3.2 Gen 2 device to the Type-C port and verify the link speed shows 10 Gbps in your operating system's device manager or system profiler.

What comes with the SY-ADA20232 and what must I source separately?

The card includes the PCIe-to-M.2 adapter with one USB Type-C port; you must provide a Molex power cable from your PSU to enable the 2 A / 5 V output.

Which M.2 module lengths and key types does this card accept?

It supports M.2 22x60 modules with B+M keying over a PCI Express 3.0 interface.
