ESTONE PCIE23A2C 5-Port PCIe USB 3.0 Expansion Card (2 USB-C, 3 USB-A)

Five USB 3.0 ports on a single x1 slot

This ESTONE PCIE23A2C card adds two USB-C and three USB-A connectors to a desktop through any PCI Express x1, x4, x8 or x16 socket. The host controller delivers a shared 5 Gbps ceiling across all ports and is backward compatible with USB 2.0 and 1.1 devices. Driver installation is required for Windows 7, 8, Vista, XP and Server 2008, while Windows 10, 11 and Mac OS 10.8.2 or later work without extra software. No external power adapter is needed; the card draws 5 V / 12 A from the slot.

Builders adding multiple peripherals to an older

The five-port layout suits users who need several high-current devices such as external drive enclosures or VR sensors at once, with each port capable of 5 V / 3 A. It will not serve anyone who requires Power Delivery fast charging, BC 1.2 charging negotiation, or video output over USB-C because the card handles data only. Buyers needing Thunderbolt protocol support or an external power connector for even higher loads should look elsewhere.

Steady 5 Gbps throughput with distributed current

Under sustained load the shared 5 Gbps bandwidth divides among active ports, so copying large media libraries to multiple drives runs at the aggregate limit rather than per-port peaks. Four onboard power modules keep the 12 A total current stable during long transfers, preventing brown-outs on power-hungry enclosures. The FRE100 controller maintains consistent signalling without thermal throttling in typical chassis airflow.
