SURF CUZ
Adds four USB 3.1 Type-C ports via a PCIe Gen3 x2 slot, delivering up to 10 Gbps data with 15 W per port and no extra power needed
This SURF CUZ add-in card adds four USB 3.1 Type-C ports to a desktop PC through a single PCI Express slot. It targets builders who need more high-speed external connections for drives or peripherals without opening the case for internal hubs. The card uses an ASM3142 controller to bridge PCIe Gen3 x2 bandwidth to the four downstream ports.
Installation requires a free PCIe x4, x8 or x16 slot; x1 and x2 slots are not compatible. A self-powered IC draws what it needs from the slot itself, so no auxiliary power cable or external adapter is required. Each port supplies up to 15 W for bus-powered devices and includes over-current protection for safe hot-plug operation.
The controller complies with the USB 3.1 Gen 2 specification and the PCI Express 3.0 base specification, delivering up to 10 Gbps per port under continuous load. Spread-spectrum clocking and PCIe link power management keep latency low during long transfers. Windows 7 requires the supplied driver; Windows 10, Linux and macOS 10.8.2 or later operate driver-free.
