It does this by offering transfers of up to 8 GT/s per lane. That roughly translates into a little less than 4GB/s, which is far more than the USB prescribed standard of 2.5GB/s (or 20Gbps). But just because PCIe 3.0 supports such a high data rate does not mean you get to avail them. At least not for the time being. Except for the card from Orico, all the cards offer 10W-15W of output power to charge your portable devices. The Sonnet Allegro offers a 7.5W, which may have limited use. Card Height

Like the Orico USB-C card, the IO Crest card also uses a 15-pin SATA port to provide power. This helps to provide a stable power supply during peak data exchanges that ensure zero errors. Therefore, there is no denying that a USB-C connection is necessary for all computers today. However, if you have a PC older than 2017, the USB-C 3.2 port is most likely missing. This means it is time for an upgrade. Continuing with the similarities, Orico’s USB-C card also uses the PCIe 3.0 slot on the motherboard. You can use any of the x4, x8, or x16 slots. However, additional lanes do not mean that you get extra speed. It would be better to use a PCIe 3.0 x4 as you may require the 8-lane and 16-lane interfaces for graphics cards or similar components.

Nailed it

As was also previously mentioned, Thunderbolt carries PCIe so this is an option for external connection.

The number of output ports controls the number of devices you can connect to the USB-C card. However, that is not the only consideration to keep in mind. Plenty of cards offers USB-C and USB-A ports on one card. Thus, choosing the right one involves understanding your need. Add Two USB-C 10Gbps Ports to Mac Pro, Windows, and Linux Computers with PCIe Slots; and Thunderbolt to PCIe Card Expansion Systems Finally, a pair of short USB-C cords are included, one USB-C to USB-C and the other USB-A to USB-C. Both are just over 3/4″ in length. While short, they’re long enough when used with a laptop although they can be a bit short when using the enclosure with a desktop depending on where your ports are. Ease of Use The device is compatible with macOS and Linux. But Windows users have to have Windows 11 to use the card. Our Take The obvious advantage is the added connectivity with a dedicated charging port. Thus, you can charge your phone on one port and use the other for bulky data transfers.PCIe Data Link Auto-Negotiation—Card auto-negotiates one lane data link in a PCIe 3.0 slot and two lanes in a PCIe 2.0 slot, ensuring full 10Gbps performance in either generation PCIe slot Also, you must consider replacing any old USB-A-only cards with the ones from Abelconn, Sinefine, and FebSmart. Not only will you get the two ports, but you can vacate a PCIe 3.0 expansion slot also. Output Power USB offers a native output power of 0.9A per port. The devices you connect to these ports draw this power for their operations. The Allegro™ USB-C PCIe (1) card supports data transfers at up to twice as fast as USB 3.0, and can also deliver 15W of power per port to USB-C bus-powered devices (three times the 4.5W specified in the USB 3.0 spec). Don’t settle for mediocre performance or insufficient power for the fastest SSDs—install an Allegro USB-C card to instantly add two Gen 2 USB 3.2 ports to your system and take full advantage of today’s SSD performance.
