EN-Labs 4-Port USB 3.0 PCIe Card

This EN-Labs expansion card adds four USB 3.0 ports to a desktop computer through an available PCI Express slot. It provides two external Type-A ports and two internal ports via a 20-pin header for front-panel connectivity. The card suits builders who need more USB 3.0 connections for peripherals or front-panel upgrades.

Installation notes and common issues

The card fits PCIe x1, x4, x8 and x16 slots and includes a full-profile bracket with a low-profile bracket supplied. A 15-pin SATA power connector is present on the board and must be connected for power-hungry devices; forgetting this cable is the most frequent reason ports appear dead. Driver installation from the included CD or a download is required before the ports become active.

NEC UPD720201 chipset and 5 Gbps limit

The NEC UPD720201 controller delivers up to 5 Gbps per port and is backward compatible with USB 2.0 and USB 1.1 devices. The single PCIe 2.0 x1 host link caps total throughput at the same 5 Gbps, so simultaneous heavy traffic on all four ports will share that bandwidth. Buyers needing higher aggregate throughput or more than four ports should choose a different solution.

Questions about this item

How do I confirm the NEC UPD720201 chipset is running at 5 Gbps after installation?

Check Device Manager under Universal Serial Bus controllers; the card should appear as a USB 3.0 host controller. Run a file transfer to a USB 3.0 flash drive and verify speeds approach 5 Gbps.

What comes in the box and which cable must I supply?

The package includes the PCIe card, a low-profile bracket, and a driver CD. You must provide a SATA 15-pin power cable from your PSU to the card's onboard connector.

Should I choose the 20-pin internal header or the two external Type-A ports for front-panel USB 3.0?

Use the 20-pin internal header to add two USB 3.0 ports to your case front panel; the two external Type-A ports are fixed at the rear bracket for rear-access devices.
