Eight USB-C 10Gbps ports on one bracket

The Sonnet Allegro Pro BEUSB3C-8PM-E adds eight USB-C ports to a Mac Pro, Windows 11 or Linux workstation through a single full-height PCIe slot. Each port delivers up to 10Gbps bandwidth and 7.5W of bus power for attached peripherals.

Fits an x8 PCIe 3.0 slot

The card occupies one x8 PCIe 3.0 lane set and uses a bridge chip with four independent USB 3.2 controllers to sustain full 1000 MB/s throughput per port even under concurrent load. Builders who need a second card or more internal slots cannot use this model.

No cables or adapters included in the package

The bracket spacing accepts eight cables or USB-C to USB-A adapters simultaneously, but none are supplied. Users must provide their own cables to connect SSDs, RAID arrays or other bus-powered devices.
