Sonnet Allegro 4-Port USB-A 3.2 Gen 1 PCIe Card

Connect USB-A devices to your compatible Windows, Mac, or Linux system using the Allegro 4-Port USB-A 3.2 Gen 1 PCIe Card from Sonnet. Built with a full-height form factor and a PCIe 2.0 x1 interface, this card has four external 5 Gb/s USB-A 3.2 Gen 1 (3.1 Gen 1/3.0) ports, each of which also provides up to 7.5W of charging power for compatible devices. Backward compatible with USB 2.0 and 1.1 devices, this card features hot-pluggable and hot-swappable device connection support with automatic device configuration and works with most USB-IF compliant USB peripherals. Additionally, this card may be used in external PCIe expansion enclosures via Thunderbolt 5, 4, 3, or 2 connectivity.

The Allegro features a PCIe 2.0 bus interface to take advantage of your computer's fast expansion card slots. This card installs easily into any PCI Express (PCIe) slot that supports a full-height card, features hot-pluggable and hot-swappable device connection support with automatic device configuration, and works with all USB-IF compliant USB peripherals.

Sonnet specially engineered the Allegro PCIe card to provide extra power through its ports without the need for you to connect an auxiliary power cable. Delivering up to 7.5W of power, this Sonnet solution supports USB 3.2 Gen 1 bus-powered hard drives, SSDs, DVD, and Blu-ray devices without the need to connect an additional AC power adapter. The Allegro also supports the USB 3.2 Gen 1 charging specification that enables you to simultaneously charge and sync your iPad, iPhone, or other device that supports USB 3.2 Gen 1 charging at up to 1.5A per device.

Got an older Mac with USB 2.0 ports, no PCIe slots, and a Thunderbolt 5, 4, 3, or 2 port? The Allegro is a great way to add four 5 Gb/s USB-A ports for use in Sonnet's Thunderbolt 2 and Thunderbolt 3 to PCIe card expansion systems, including Echo Express and xMac desktop and rackmount systems.

Have a multi-slot Thunderbolt 5, 4, 3, or 2 to PCIe card expansion system with an open slot? Installing an Allegro USB-A 3.2 Gen 1 PCIe 4-Port card is an excellent way to inexpensively add four 5 Gb/s USB-A 3.2 Gen 1 ports to your computer.
