EXSYS EX-11081-2 PCIe USB 3.2 Gen 1 -kortti 1+1 portilla (Renesas)

The EXSYS EX-11081-2 stands out by adding four USB 3.2 Gen 1 ports through a single PCIe x1 slot, with two ports accessible from the rear bracket and two more routed to a 19-pin header for front-panel or internal devices. This dual-layout approach gives system builders flexibility that typical USB expansion cards lack.

Highlights

• Renesas µPD720202 host controller ensures stable 5 Gbit/s operation and UASP support for faster storage transfers.
• Backward compatible with USB 2.0 and 1.1 devices, so older peripherals continue to work without issues.
• Low-profile design with both standard and low-profile brackets included fits slim desktops and 2U rackmount chassis.
• SATA power connector supplies up to 900 mA per port, enough for bus-powered external drives.

In daily use

Installing the card is straightforward: plug it into an available PCIe x1 slot, connect a SATA power cable, and the operating system loads the built-in xHCI driver. The two internal ports are ideal for connecting front-panel USB 3.0 hubs or internal card readers, while the rear ports handle external drives, cameras, and other high-speed devices. Hot-swap support lets you connect or disconnect devices without rebooting.
