Each new version of the PCI Express standard has increased the theoretical throughout for all PCI-e expansion slots ranging from x1 to x16. USB-C: is a symmetrical connector supported by 3.2 that eases insertions.USB 3.2: offers increased bandwidth via multi-lane operations.USB 3.1: introduces SuperSpeed+ or transfer rates up to 10 Gbps.Note that some USB 3.0 PCI Express cards also support: USB 3.0 is referred to as SuperSpeed USB because it increased the theoretical transfer rate of the standard to 5 Gbps. What is USB 3.0 and is it backward-compatible?Īll USB versions are backward- and forward-compatible, but maximum throughput and feature limitations will always be dictated by the earliest version supported by a connected device. PCIe x1 indicates one lane, which generally provides more than enough throughout to meet the needs of USB. Every PCI Express expansion port that a motherboard supports is assigned a number of lanes. PCI Express-which is often abbreviated as PCIe or PCI-e-was introduced in 2004 as a high-speed alternative to the original PCI. PCI stands for Peripheral Component Interconnect and was introduced in 1992 as a type of local computer bus that could be used to attach components to a computer. They, therefore, expand not just the physical connections but the overall throughput and the maximum number of USB devices that the motherboard can communicate with simultaneously.

Ports added externally generally only have access to whatever USB data channels already exist on the motherboard. However, this is an important distinction beyond the obvious. These products are often referred to as internal port expansion because they connect inside the computer rather than externally.

A USB 3.0 expansion board often adds four, eight, or even more ports. In desktop computing, an expansion card is a component that’s inserted into an open expansion port on a motherboard in order to add functionality to the system. USB 3.0 Internal Port Expansion Cards for PCI Express x1 ports let you add the USB ports you need in a way that’s seamless to your desktop computer’s overall design. Even if your PC provides six or more ports, it may seem like you never have enough. Many of the devices that you use on a daily basis support USB connections.
