SMUGDESK PCIe 3.0 x4 to Type-E 20Gbps Adapter with SATA Power

SKU CH-WTVR-9DQ13

Adds a 20Gbps internal Type-E port with SATA power to a PCIe 3.0 x4 slot

  • PCIe 3.0 x4 lane width enables 20 Gbps throughput for fast transfers
  • Internal Type-E header connects directly to front-panel USB-C cable or riser
  • 15-pin SATA power connector delivers stable power for demanding USB-C devices
  • Standard PCI bracket fits x4, x8 or x16 slots for easy installation
  • Windows and Linux support provides broad system compatibility for daily use

PCIe 3.0 x4 expansion card

This adapter adds a single internal Type-E header that runs at 20Gbps using PCIe 3.0 x4 bandwidth. It is aimed at desktop builders who want to connect a modern front-panel USB-C cable or extension riser to an available PCIe x4, x8 or x16 slot.

Check slot and power first

Verify the motherboard has a free PCIe x4, x8 or x16 slot and that the case can accept a standard PCI bracket. A 15-pin SATA power connector from the PSU must be attached for the card to supply enough current to high-power USB-C peripherals. The board works with Windows and Linux without extra drivers.

Thermals and power in use

The card draws its operating power from the PCIe slot and the auxiliary SATA connector, so total draw stays modest and no active cooling is required. Passive heat dissipation through the bracket and PCB keeps temperatures low during sustained 20Gbps transfers. Acoustic output is effectively silent because there are no moving parts.

Questions about this item

What cables or parts come in the box and what must I supply myself?

The adapter includes a standard PCI bracket and the 15Pin SATA power connector; you must provide the front-panel Type-E cable or riser cord that connects to your chassis.

How do I decide between the available versions or capacities of this card?

This model is offered in a single configuration — PCIe 3.0 x4 with one internal Type-E port at 20Gbps — so there are no alternate versions or capacities to choose from.

What does the 20Gbps headline speed mean once the card is installed in my PC?

The card delivers up to 20Gbps over the internal Type-E header when seated in a PCIe 3.0 x4 slot, matching the USB3.2 Gen2×2 specification for front-panel USB-C devices.
