Add USB 3.0 Ports to Your PC with a PCIe Expansion Card

If it seems like you never have enough USB ports for your devices, then internal expansion via an open PCI Express x16 slot may be an option. You can add four or more ports not only for data transfers, but also to achieve the capacity to charge smartphones, power external hard drives, and much more.

What are USB 3.0 PCIe x16 expansion cards?

Expansion cards are so named because they’re inserted into a motherboard via an open expansion slot in order to add or enhance system capabilities. These USB 3.0 cards require an open PCI Express x16 slot specifically. The advantage of internal expansion is not only that it adds physical USB connections but also that it provides dedicated throughput channels. In addition, it increases the number of USB devices that can send data to and from the system.

How do different USB 3.x versions affect these cards?

There have been refinements to the USB 3.0 standard, and the specific version supported by the card you choose will dictate transfer rates as well as feature support. Be mindful that all USB versions, including those prior to 3.0, are backward-compatible. The different available versions are:

  • USB 3.0: This is SuperSpeed and supports 5 Gbps over one lane.
  • USB 3.1: This is SuperSpeed+ and supports 10 Gbps over one lane.
  • USB 3.2: This is SuperSpeed or SuperSpeed+ and supports 5 to 10 Gbps over one to two lanes.
  • USB-C: This is a connector type supported by 3.2 that makes USB plugs easier to connect.

What does x16 indicate?

Peripheral component interconnect (PCI) is a bus for connecting components to motherboards. PCI Express, often abbreviated PCIe or PCI-E, is an update to the standard that allows for higher transfer rates and lets cards draw power through the connection. Each PCIe port is assigned between one and 16 data lanes. PCIe x16 indicates 16 data lanes.

How do the different PCI Express versions affect these cards?

Each PCI Express version has increased the maximum throughput for each data lane. PCIe 1.0 could achieve 4 GB/s over 16 lanes, while PCIe 5.0 can achieve 63Gbps. In real-world applications, PCI Express 2.0 is considered to provide enough speed and bandwidth for whatever USB 3.0 can offer. Even so, matching the PCIe version to what your mainboard supports may offer benefits for the future.

Do these cards require a power connection on the motherboard?

The PCI Express standard ensures that expansion cards get the power they require locally via the PCIe port itself. Therefore, a dedicated power connection isn’t a fundamental requirement. However, many USB devices, such as charging smartphones and external hard drives, have power requirements that exceed the local provisions of PCI Express. Some USB 3.0 cards that will offer or require a SATA power connection in order to meet those additional power demands.
