Delock PCI Express x4 Card to 4 x USB Type-C™ 10 Gbps - Low Profile Form Factor

Modern laptops and small form factor PCs often lack enough high-speed USB ports for connecting multiple external drives, docking stations, or VR peripherals. The Delock 90935 solves this by adding four USB Type-C™ ports with 10 Gbps bandwidth each, directly through a PCIe x4 slot. This low profile card fits slim desktops and servers, and includes both standard and low profile brackets for universal compatibility.

Tips

For optimal performance, install the card in a PCIe x4 or larger slot and connect the SATA power cable from your power supply. Ensure your operating system has the latest USB drivers, and use high-quality USB-C cables rated for 10 Gbps to achieve maximum transfer speeds. When using bus-powered devices, the SATA power connection is required to deliver full power to all ports.
