Adds five USB 3.2 ports — three Type-C and two Type-A — at up to 10 Gbps through a PCI Express slot
The ESTONE PCIE22A3C3.2 adds five USB 3.2 ports to a desktop through a single PCI Express slot. Three ports use the Type-C connector and two use Type-A, all sharing up to 10 Gbps bandwidth. It suits owners who need more high-speed sockets for external drives, input devices or VR headsets.
The card draws its operating power directly from the PCI Express slot, so no auxiliary power cable is required. Because it has no active cooling, it adds no fan noise to the chassis. Typical idle and light-transfer power consumption stays within the slot’s rated delivery.
During prolonged bulk transfers each port maintains the 10 Gbps ceiling as long as the attached device and host controller can sustain it. The onboard over-current and static protection on every port prevents a single misbehaving device from tripping the whole card. Actual throughput will fall if the connected storage or peripheral cannot keep pace.

Insert the card into any PCIe x1, x4, x8 or x16 slot; the step people miss is installing the RENESAS/VLI USB 3.2 driver from the included CD before the ports will work at 10 Gbps.
No scheduled maintenance is required; the card draws power from the PCIe slot and each port has overcurrent and static protection, so only a driver reinstall after a major OS upgrade might be needed.
The single PCIe 3.0 x1 lane caps total throughput at roughly 8 Gbps, so sustained transfers across all 3 USB-C and 2 USB-A ports will hit that bottleneck first.
