## Long description

The Sonnet Allegro Max USB-C 20Gbps 1‑port PCIe expansion card provides a single high-speed USB‑C connection for desktop PCs and workstations with an available PCIe slot. Engineered to deliver up to 20 Gbps of throughput, this PCIe USB‑C card enables faster transfers to external SSDs, modern peripherals, and USB‑C docks. The low-profile design and standard bracket options make it compatible with most desktop chassis, allowing users to add modern connectivity without replacing the host system.
Advantages
This expansion card offers a reliable, native USB‑C interface with up to 20 Gbps bandwidth for high-performance data transfer. It supports plug-and-play operation in supported operating systems and includes a single-port implementation that reduces system complexity while maximizing throughput for connected devices. The card’s compact, PCIe-mounted form factor preserves internal drive bays and external ports, providing a practical upgrade path for systems that lack modern USB‑C outputs.
Suitable for
Adding USB‑C 20 Gbps connectivity to older desktops and workstations
High-speed transfers to external NVMe or SSD enclosures
Connecting USB‑C peripherals such as audio interfaces, capture devices, and docking stations
Workflows requiring faster backup, media transfer, or data offload
Key specifications
Interface: PCIe x4 (or compatible PCIe slot as specified by the host)
External port: 1 × USB‑C supporting up to 20 Gbps data rate
Form factor: Low-profile with standard bracket included for compatibility
Power: Draws power from PCIe slot; supports bus-powered peripherals within USB‑C power limits
Compatibility: Designed for desktop and workstation systems with available PCIe expansion slots
How to use
Power down the computer and unplug it from the mains. Open the computer chassis, identify an available PCIe slot and remove the corresponding slot cover. Insert the Allegro Max USB‑C expansion card into the PCIe slot until it is firmly seated and secure the bracket to the chassis. Reassemble the case, reconnect power, and boot the system. Install any required drivers supplied by the operating system or from the card manufacturer if prompted. Connect USB‑C devices to the external port to begin data transfers at supported speeds.
Usage recommendations
For optimal performance, use a PCIe slot that provides at least x4 lanes and connect devices with USB‑C cables rated for 20 Gbps or higher. Ensure the host operating system is updated and, if applicable, install Sonnet-provided drivers. Avoid overloading the card with multiple high-power devices beyond the PCIe slot’s power delivery capability; use externally powered hubs or docks when connecting several peripherals that require significant power.
