  • No external power needed thanks to built-in self-powered IC

PCIe x4 to dual USB-C 10Gbps 4K 60Hz adapter

The LORDWORLD expansion card uses an ASM3142 chipset to convert a PCIe x4 slot and a Mini DisplayPort 1.4 input into two USB-C ports. Each port delivers up to 10Gbps data throughput and supports 4K video at 60Hz. The card draws power from the slot and includes a self-powered IC so no external supply is needed. Windows 10, 11, macOS and Linux work without drivers; Windows 7 requires a driver installation.

Adds two USB-C ports with video and data

Builders who want to add USB-C connectivity and 4K 60Hz video output to a desktop via an internal PCIe slot will find this card suitable. It is not for systems that lack a Mini DisplayPort 1.4 source on the graphics card, nor for users who need more than two USB-C ports. The card also does not suit builds without a free PCIe x4 slot.

Requires Mini DisplayPort 1.4 input for 4K 60Hz

The single specification that decides fit is the Mini DisplayPort 1.4 input from the graphics card; without it the card cannot pass 4K 60Hz video to the USB-C outputs. The ASM3142 chipset handles the 10Gbps USB 3.1 Gen2 data rate and 5V power delivery on each port.

Questions about this item

Does the ASM3142 chipset run hot or draw extra power when both USB-C ports sustain 10Gbps transfers all day?

No separate power supply is needed because the card includes a self-powered IC that draws from the PCIe slot, keeping heat and power draw low during continuous 10Gbps operation.

Must my graphics card have a Mini DisplayPort 1.4 output for the 4K 60Hz video to appear on the USB-C ports?

Yes, a Mini DisplayPort 1.4 connection from the graphics card is required to pass 4K 60Hz video to the dual USB-C outputs; the card cannot generate video on its own.

Will the card work in an older motherboard that only has PCIe 2.0 x4 slots?

The adapter installs in any PCIe x4 slot; Windows 10, 11, macOS 10.8.2+ and Linux run without drivers, while Windows 7 needs the supplied driver.
