Green PCIe card with two USB-C ports on a metal bracket

Corn Electronics

Corn Electronics USB 3.1 Two-Port 10Gb PCIe Card

SKU CH-8MP4-B68BE

Adds two 10Gbps USB-C 3.2 Gen 2 ports via PCIe with 15W power each, auto-negotiating full speed in 2.0 or 3.0 slots

  • Adds two 10 Gbps USB-C ports for faster transfers
  • Each port delivers up to 15 W to power bus-powered drives
  • Independent power regulation prevents cross-coupled glitches and accidental disconnects
  • Auto-negotiates PCIe lanes for full 10 Gbps speed in 2.0 or 3.0 slots
  • Backed by free lifetime support since 1986

Two 10Gbps USB-C ports

This PCIe add-in card adds two SuperSpeed+ USB-C ports, each capable of 10Gbps transfer rates. It fits Mac Pro systems with PCIe slots, Windows PCs, Linux machines or Thunderbolt-to-PCIe expansion chassis. The USB 3.2 Gen 2 interface moves data up to twice as fast as USB 3.0 connections.

Suited for high-speed external storage

The card suits users who connect bus-powered SSDs, SSD RAID arrays or hard drives that draw up to 15W per port. Independent power regulation on each port prevents cross-coupled glitches that can cause accidental disconnects. Builders who need more than two ports or require internal headers should consider a different controller.

Sustained throughput via lane negotiation

Under continuous load the card auto-negotiates its PCIe link width: one lane in a 3.0 slot or two lanes in a 2.0 slot. This behaviour preserves the full 10Gbps per port regardless of slot generation. The design targets steady-state transfers rather than short burst speeds.

I korthet

  • Adds two 10 Gbps USB-C ports for faster transfers
  • Each port delivers up to 15 W to power bus-powered drives
  • Independent power regulation prevents cross-coupled glitches and accidental disconnects
  • Auto-negotiates PCIe lanes for full 10 Gbps speed in 2.0 or 3.0 slots
  • Backed by free lifetime support since 1986

Frågor om den här produkten

What free PCIe slot width does the Corn Electronics card need to run at 10 Gbps?

It auto-negotiates one lane in a PCIe 3.0 slot or two lanes in a PCIe 2.0 slot, delivering full 10 Gbps throughput in either generation.

Will the card supply 15 W to each USB-C port if I keep my older USB 3.0 drives connected?

Yes, each port provides up to 15 W independently, so legacy USB 3.0 devices draw only what they need while newer bus-powered SSDs receive the full 15 W.

How can I verify both ports are operating at 10 Gbps after installation?

Check the OS device manager or system profiler — each port should enumerate as USB 3.2 Gen 2 (10 Gbps) and attached SSDs should show transfer speeds approaching 10 Gbps.
