SIIG USB 3.0 7-Port PCIe Host Adapter, 7 Ports | USB 3.0, PCIe

Expand a PCIe-enabled desktop with seven USB 3.0 ports and keep high-demand peripherals connected without relying on external hubs. The SIIG LB-US0514-S1 is designed for systems that need more direct USB access for storage, imaging devices, input hardware, and other bus-powered accessories. By moving expansion onto the PCIe bus, this adapter gives IT teams a cleaner path to add ports where desktop I/O is already constrained. It is a straightforward fit for workstation refreshes, lab systems, and service desktops that need dependable USB connectivity for multiple devices at once. For environments where port count matters, direct expansion is often preferable to daisy-chained accessories. This card helps reduce cable clutter, preserves front-panel ports for temporary use, and supports a more controlled desktop layout. It is a practical choice when the goal is to extend capability without replacing the host system.
