Sonnet launches Allegro Pro USB-C 8-Port PCIe card for Mac, Windows, and Linux

Believe it or not, some modern desktop computers don't have any USB-C ports, and for those that do, many only have one or two of the ports. Thankfully, if you have a free PCIe slot in your machine, you can easily add more.

A new card from Sonnet takes adding USB-C ports to another level. Called "Allegra Pro," it offers an impressive eight external Type-C ports all running at USB 3.2 Gen 2 speed (10Gbps).

Carrying model number "ECHO-USB3C-8PM-E," the Allegro Pro uses a full PCIe 3.0 x16 slot running at x16 speed. In other words, it won't fit in a smaller slot, and it won't run at full speed if the x16 slot runs at x8, x4, or x1. You will potentially need to use the x16 GPU slot on your motherboard if you don't have additional x16 slots. No free x16 slots? Sorry, this card is simply too hardcore for your machine.

The Sonnet card is compatible with Mac, Windows, and Linux computers with an available x16 PCIe slot, and Mac and Windows computers with Thunderbolt ports when installed in a Thunderbolt to PCIe card expansion system with an available x16 PCIe slot," says Sonnet.
