PCIe USB 3.2 Type-C Card

The ESTONE PCIE24C adds four external USB Type-C ports to a desktop through a PCI Express x4 slot. It targets builders who need more high-speed ports for external storage or peripherals. The card uses an ASM3142 controller and fits x1, x4, x8 or x16 slots. It does not serve buyers who require DisplayPort Alt Mode or USB Power Delivery negotiation.

Driver CD and SATA Power Option

A driver CD is included for Windows 7 and XP systems; Windows 8 and later, macOS 10.8.2 and above, and Linux typically load drivers automatically. An optional SATA power connector can supply up to 15 W per Type-C port when motherboard power is insufficient. The bundled screws secure the bracket to the case.

Installation Notes

The card draws slot power by default, so no extra cable is mandatory unless port current exceeds the slot budget. Common issues arise on PCIe 1.0 platforms, which are not supported, and on Windows 7 or XP where the CD driver must be installed manually. Each port includes independent over-current and short-circuit protection.

Questions about this item

Will the ASM3142 controller need a firmware update to stay compatible with future operating systems?

The ASM3142 controller runs on drivers that install automatically on Windows 8 and later, macOS and Linux; no separate firmware updates are mentioned.

At sustained loads, does the PCIe 2.0 x4 link or the 10 Gbps USB 3.2 interface saturate first?

The PCIe 2.0 x4 link caps at roughly 16 Gbps, so four 10 Gbps ports can exceed the upstream bandwidth before the USB interface does.

How much heat and power does the card draw when all four Type-C ports run at 5 V 3 A continuously?

With the optional SATA power connected, the card can deliver up to 15 W per Type-C port; without it, each port is limited to 5 W from the PCIe slot.
