Adds seven USB 3.0 ports — five Type-A and two Type-C — through a single PCI Express x1 slot at 5 Gbps
The ESTONE PCIE25A2C adds seven USB 3.0 ports to a desktop computer through a single PCI Express x1 slot. Five ports use the traditional Type-A connector and two use the reversible Type-C connector. The card draws all required power from the motherboard slot, so no external power cable is needed.
This card suits users who want to attach multiple keyboards, mice, external drives, printers or cameras at 5 Gbps speeds. It is not for systems that lack a free PCI Express x1 to x16 slot. It is also not for anyone who needs Thunderbolt protocol support or video output from the added ports.
Each port delivers up to 5 Gbps bandwidth, which is the USB 3.0 specification limit. Actual throughput will vary with the connected device and the host controller. The single specification that decides fit is whether your workflow requires this 5 Gbps ceiling or a faster interface.

The card uses a PCIe 2.0 x1 lane, which provides up to 5 Gbps of host bandwidth. All seven USB 3.0 ports share this lane, so simultaneous transfers across multiple ports will be limited to that aggregate throughput.
It fits any PCI Express x1, x4, x8 or x16 slot and occupies a single low-profile bracket. The board measures 4.92 by 4.06 by 1.06 inches, so verify your case has enough clearance behind the slot.
Power off the PC, insert the card into a free PCIe slot, secure it with the supplied screw, then boot. The critical step is installing the Renesas/VLI USB 3.0 driver from the included CD or a downloaded package before the ports will enumerate correctly.
