USB 3.2 Gen2  type-C + type-A 接頭 10Gbps 高速介面

台灣大廠祥碩ASM3142晶片

擴充卡/擴展卡 全高和半高兩款PCIe擋板

向下相容 USB 3.1 Gen 1  NVME外接盒搭檔

使用15針SATA電源  可提供電源輸出

可將電腦的PCI- E高速資料傳輸介面轉換成 2個USB3.1 Gen2 高速資料傳輸介面，且向下相容USB3.0、USB2.0和USB1.1設備，USB3.1的速度是 USB3.0的翻倍速度，更是遠遠高於USB2.0的速度，支援USB設備的熱插拔功能，專門為個人電腦，消費電子產品和通訊設備提供更快更高的速率而製造。

雙埠 USB 3.2 Gen 2 Type-C，提供高達 10 Gb/s 傳輸速度
向下相容 USB 3.2 Gen 1、USB 2.0 及 USB 1.1介面裝置。
支援 UASP (USB Attached SCSI Protocol) 傳輸通訊協定
雙埠 USB 連接埠，具備獨立的過電流與短路保護。
支援 Windows® 8.x / 10 (32/64位元) 無須額外安裝驅動器率

備註：

I/O 擴充卡屬於USB3.1 GEN2標準，向下相容USB3.0和USB2.0

I/O 擴充卡是4X介面，可以插到4X 8X 16X插槽上。

I/O  擴充卡是1X的可以插到1X 4X 8X 16X插槽上。

1X一定要主板支持PCI-E3.0才能跑到高速，否則只有3.0速度。

因為SATA電源座都是塑膠的，因此線是比較緊的，插線時一定要頂住座子的後面再插線，用力插線時會使座子翹起來。因USB3.1供電可以用自帶的DC-DC供電，不用插SATA電源也能工作。

USB 3.1 Gen2介紹

USB 3.1（SuperSpeed+，官方全名：SuperSpeed USB 10 Gbps）是基於USB 3.0改良推出的USB連接介面的最新版本，此技術其中在生活上應用最出名的是USB Type-C介面。速度於Thunderbolt 相同。

USB 3.0更名為　USB 3.1 Gen1速度不變（5Gbps），USB 3.1更名為　USB 3.1 Gen2速度為10Gbps。

ASMedia ASM3142 介紹

ASMedia ASM3142 is the next generation Universal Series Bus xhci host controller, bridging PCI Express to USB3.1 Gen-II, compliant with USB3.1 Specification Revision 1.0 and Intel eXtensible Host Controller Interface specification revision 1.1. It also supports backward compatible with legacy USB function and devices, compliant with USB Attach SCSI Protocol revision 1.0, supporting the function of debugport on port A of USB.

ASMedia ASM3142 also supports the new feature of USB3.1 Gen2, named Multiple INs to achieve fully utilization rate of 10Gbps data rate, taking advantage of the available bandwidth of USB3.1 Gen2 bus.

ASM3142 supports two USB3.1 Gen-II ports and perform trusting high speed bandwidth with PCI Express Gen-III x2 supporting. It uses advance process with low voltage supply, following standard PCI Express/USB bus power management and advance chip power management to reduce total power consumption efficiently under idle/standby state.

ASM3142 integrates ASMedia self-designed PCI Express/SuperSpeed USB/USB2.0 PHY, supporting the proprietary driver for Windows 7 and in box driver for Windows 8.0, Windows 8.1, Windows 10 and various Linux kernels. The application of ASM3142 includes Motherboard, Desktop PC, Notebooks, Workstations, Servers, Add-in cards, PCI Express based embedded platform.
