Two USB 3.1 internal headers

This PCIe 2.0 x2 add-in card provides two 19-pin USB 3.1 internal connectors, adding front-panel SuperSpeed ports to a desktop. It uses the ASMedia ASM1142 controller and draws 5 V power from a SATA 15-pin connector. Pericom PI3EQX1002B ReDriver chips extend reliable cable reach beyond the standard one-metre limit. The card fits low-profile brackets and supports Windows 7 through 10, Ubuntu, Linux and Mac OS.

Builders adding front USB 3.1 ports

Suits system integrators and enthusiasts who need two internal USB 3.1 headers on a motherboard that lacks them. Not for users whose chassis only offers USB 2.0 front-panel cables or who require external USB Type-A or Type-C ports directly on the bracket. Buyers without a free PCIe x2 or larger slot and a spare SATA power connector should look elsewhere.

PCIe 2.0 x2 host interface

The card connects through a PCI Express 2.0 x2 slot, delivering up to 10 Gbps of theoretical bandwidth to match the USB 3.1 10 Gbps specification. This single link width and generation determines whether the card will operate at its rated speed in a given motherboard slot.

Questions sur cet article

How do I install the Silverstone SST-ECU04-E and what step is often missed?

Insert the low-profile card into a PCI-E 2.0 x2 slot, then connect the 19-pin USB 3.1 header to the motherboard; the step many miss is plugging the SATA 15-pin power connector so the ASM1142 controller receives 5 V.

What maintenance or replacement will this card need later?

No scheduled maintenance is required; if a Pericom PI3EQX1002B ReDriver or the ASM1142 controller fails after extended use, the entire add-on card would be replaced.

What limit appears first under sustained 10 Gbps transfers?

The PCI-E 2.0 x2 host interface caps sustained throughput at 10 Gbps, so the bus bandwidth is the first bottleneck during continuous high-speed operation.
