This article covers PCIE USB3.2 高速拡張カード 4x TypeC + 4x USB3.2 PCI-E X16 デスクトップコンピュータ用 USB アダプタ USBC コントローラインターフェイス超高速拡張.

Overview

This expansion card adds up to eight USB 3.2 Gen2 ports to a desktop PC via a PCI Express x16 slot. It features the ASM3142 controller, offering four Type-C and four Type-A ports, each capable of 10Gbps transfer speeds. Ideal for users who need more high-speed USB connectivity for external SSDs, video capture devices, or multiple peripherals, it provides a straightforward solution to port limitations on modern motherboards.

Compatibility Guide

The card fits any standard PCI Express x16 slot, though it requires at least x4 lanes to fully utilize all ports simultaneously. It is compatible with ATX, Micro-ATX, and Mini-ITX motherboards. Power is drawn from the PCIe slot, so no additional power cable is needed. It works with Windows 10/11, Linux, and other major operating systems without additional drivers in most cases, but updating chipset drivers is recommended.

Product Info

Sold on at a reference price of approximately ¥12,266, this card occupies a mid-range position for users seeking affordable USB expansion. The ASM3142 chipset provides stable 10Gbps performance across eight ports, with four USB-C connectors being a notable feature. Warranty coverage depends on the seller's policy, typically aligning with 's return and replacement guidelines.

Best Use Cases

This expansion card is perfect for desktop users who have run out of rear USB ports. Creative professionals connecting multiple external SSDs or gamers using VR headsets alongside other USB devices will benefit from the extra bandwidth and port count. It also serves office environments where many USB peripherals need to be connected simultaneously, offering a simple plug-and-play upgrade.

Things to Consider

Pay attention to PCIe lane availability: if the slot operates at x2 or lower, all ports may not achieve full 10Gbps speed. Some motherboards or BIOS settings may not recognize the card in certain slots, so check the motherboard manual beforehand. The ASM3142 supports USB 3.2 Gen2 (10Gbps) but not Gen2x2 (20Gbps). Since the card is bus-powered, connecting multiple high-power devices may require a powered USB hub to maintain stability.
