Four-port USB 3.0 kit with 3.5" front panel

This EN-Labs PCIe expansion kit adds four USB 3.0 ports to a desktop PC using a single PCI Express slot. Two Type-A ports sit on the card bracket while two more reach a 3.5-inch front-panel module via a 20-pin internal header. The NEC UPD720201 controller delivers up to 5.0 Gbps transfer rates and is backward compatible with USB 2.0 and 1.1 devices.

Check slot and header before ordering

Verify that your motherboard has a free PCIe x1, x4, x8 or x16 slot and a spare USB 3.0 20-pin internal header for the front-panel cable. The card draws power from the PCIe slot and includes a 15-pin SATA power connector for extra current, so confirm your power supply has an available SATA lead. Supported operating systems include Windows XP, 2003, Vista, 7, 8, 10 and Linux.

Full-profile bracket and 3.5-inch drive-bay panel

The card uses a full-profile PCI slot cover and fits standard chassis dimensions. A 20-pin to dual Type-A splitter cable connects the internal header to the included 3.5-inch front panel, which mounts in a floppy drive bay. The SATA 15-pin power input supplements slot power for demanding peripherals, while the x1 PCIe 2.0 host interface provides sufficient bus bandwidth for the four ports.

Questions about this item

What comes in the EN-Labs PCIEU32S20KIT box and do I need any extra cables or brackets?

The kit includes the PCIe card, a driver CD, and a 3.5-inch front panel with a 20-pin to dual USB-A splitter cable. The card fits a standard full-profile slot and draws power from the PCIe bus; a SATA power connector is also present for high-draw devices.

How do I decide between the external and internal USB 3.0 ports on this card?

The card provides two external Type-A ports on the bracket and a 20-pin internal header that connects to the supplied 3.5-inch front panel for two more Type-A ports. Use the external ports for permanent peripherals and the front panel for convenient front-access drives or flash sticks.

What does the 5.0 Gbps rating mean once the card is installed in my PC?

Each USB 3.0 port can signal at up to 5.0 Gbps, matching the SuperSpeed USB 3.0 standard. The PCIe 2.0 x1 host link also tops out at 5.0 Gbps, so total bandwidth is shared across all four ports; real-world throughput will be lower due to protocol overhead and system load.
