With USB-C becoming mainstream, here are the best USB-C PCIe cards that allow you to add Type-C connectivity to your motherboard. USB Type-C is now a standard connectivity protocol. Most laptops, monitors, and peripherals come with the reversible, flippable connector.

If you don’t have a Type-C connector on your computer, don’t throw your motherboard yet. There are many USB-C to PCIe adapters in the market that can give life to your old PC.

USB-C has been around for a while now, and most manufacturers are finally adopting the technology in their devices. From smartphones and displays to peripherals such as storage drives and VR headset, almost every device is getting a Type-C upgrade.

If you’re still using legacy Type-A ports, it’s high time to get an upgrade. USB-C not only ensures cross-platform compatibility, but it also provides significant performance improvements.

The Type-C standard is a small reversible connector that supports power, data, and video over a single cable. It helps clear clutter on your desk and provides a real boost in transfer speeds up to 10Gbps.

USB-C ports built on the second generation of USB 3.1 have max speeds of 10Gbps, which is twice the speed of USB 3.0 and 20 times faster than USB 2.0 connectivity.

It is a real boost in performance when coming from USB2.0 or USB3.0, which most older motherboards support. You also get the flexibility of Type-C standard, allowing you to connect most of the latest devices and future-proof yourself.

What Is A USB-C PCIe Card?

A USB-C PCIe Card is an adapter than installs to a PCI Express expansion slot in a motherboard to enable USB Type-C connectivity. It’s a cost-effective way to add USB-C standard to your rig without upgrading it to a new motherboard.

Things to Consider When Choosing a PCIe USB-C Card

Like any other device, USB-C PCIe Cards aren’t the same. So before spending your money, it’s essential to determine if the card will solve your problems. Here are the factors to consider in PCIe USB-C adapter:

Motherboard Compatibility

Will the PCIe card work on your PC?

Most USB-C PCIe Cards come with a PCI Express x4 interface. Most gaming rigs and PC builds probably have a few components connected to the PCI Express expansion slots. Check the availability of an open PCIe slot beforehand.

A PCIe x4 adapter card can install to a PCIe x4, x8, or x16 expansion slot. For adapters with a single lane (x1) PCIe interface, you can plug them to almost all PCIe interfaces.

These USB-C PCIe Cards will not work with a PCI expansion slot.

Power Requirements

There are two types of USB-C PCIe cards when it comes to power requirements. Those powered by the PCIe bus and those that draw power from the motherboard Power Supply Unit via a SATA connector.

Bus-powered expansion cards require no additional power. Some include dedicated regulators and circuits to channel the power from the PCIe bus to USB ports. Ordinary USB-C PCIe cards require the PSU’s power via the SATA connectors or Molex for some old motherboards.

Kindly note that when using power-hungry peripherals such as hard drives, you’ll need more power output, or the drives will occasionally disconnect. Aim for adapters with 7.5W power output per port.

Type of Ports and USB Controllers

Some USB-C PCIe cards come with USB-C and USB-A ports. Depending on your needs, you can have a port with a USB-C and multiple USB-A ports. Getting an adapter with both ports is excellent since you have to invest in dongles anymore.

When shopping for USB-C PCIe cards, the number of USB controllers in vital. For instance, a card with four ports and a single USB controller shares the bandwidth amongst them, which can be slow. To solve this, some manufacturers include more than one USB controller to maintain higher speeds on each port.
