PCIe USB controller Sonnet USB3-7PM-E — 7-port USB 3.2 card for PCI Express

The Sonnet USB3-7PM-E is a PCIe USB controller card that provides seven USB 3.2 ports for installation in a PCI Express slot. It expands a desktop workstation or server with additional high-speed external and internal USB connections, enabling users to connect multiple peripherals and storage devices. The card is designed to increase I/O versatility and simplify device management where native USB ports are insufficient.

Advantages

The card offers seven USB 3.2 ports to support simultaneous connections of external drives, peripherals and other high-bandwidth devices while maintaining backward compatibility with USB 2.0/1.1 devices. Installation in a PCI Express slot provides direct host connectivity and reduced latency compared with some external hubs. The compact, bracket-mounted design allows easy integration into standard desktop and server chassis without external power reconfiguration in many setups.

Suitable for

• Expanding USB connectivity on desktop workstations and tower servers
• Connecting multiple external storage devices for data transfer and backups
• Adding ports for USB audio interfaces, video capture devices and peripherals
• Systems used for content creation, data acquisition and development that need additional high-speed USB ports

Key specifications

• Interface: PCI Express x1 (fits into compatible PCIe slots)
• Ports: Seven USB 3.2 (backward compatible with USB 2.0/1.1)
• Transfer rates: USB 3.2 Gen 1 speeds up to 5 Gbps per port (subject to host and device capabilities)
• Form factor: Low-profile bracket compatible with standard and small form factor chassis (adapter bracket may be included or available separately)
• Power: Bus-powered via PCIe slot with optional supplemental power for multiple high-draw devices depending on system configuration

How to use

Power down the computer and unplug it from the mains before installation. Open the chassis, locate an available PCI Express slot and insert the card firmly into the slot, securing the bracket to the case. If the system or connected devices require additional power, attach any supplemental power cable according to the system documentation. Close the chassis and power on the computer. Install drivers if the operating system does not automatically recognize the card; follow the driver installation instructions provided by the system or device vendor. After driver installation, connect USB devices to the card’s external ports and verify device recognition and transfer speeds within the operating system.

Usage recommendations

For stable operation and optimal throughput, place high-bandwidth devices on separate ports, avoid using multiple high-draw devices simultaneously without supplemental power, and ensure the host system BIOS and operating system are updated to support USB 3.2 over PCIe. Consult chassis and power specifications before connecting many power-hungry peripherals.
