Allegro USB 3.0 4-Port PCIe Card

The Sonnet Allegro USB3-4PM-E adds four SuperSpeed USB 3.0 ports to a Mac Pro tower, Windows PC or Thunderbolt-to-PCI Express expansion system. It connects through a PCI Express slot and delivers up to 10W of power per port without an auxiliary cable. This enables full performance for bus-powered hard drives, SSDs and optical devices.

Suited for adding high-speed ports to desktop

Ideal for users who need to connect multiple USB 3.0 storage drives, SSDs or Blu-ray devices to a desktop system with an available PCIe slot. Not suited for laptops or small-form-factor PCs that lack internal PCI Express expansion. Buyers who need more than four ports or require a different interface should look at other solutions.

No auxiliary power cable required

The card supplies up to 10W per port directly from the PCIe slot, removing the need for a separate power connection. This simplifies installation and supports bus-powered peripherals immediately. Driver software is included for Windows and macOS compatibility.
