PCI Express x4 internal USB 20 Gbps Type-E (Key A) card, Low Profile — DELOCK 91070

The DELOCK PCI Express x4 internal USB 20 Gbps Type-E (Key A) card is an expansion card that adds one internal high-speed USB Type‑E (Key A) port to compatible desktop systems. Designed for installation in a PCIe x4 slot, this low-profile card provides an internal connection that supports data transfer rates up to 20 Gbps. It is intended for use in compact workstations and desktops where an internal 20 Gbps USB interface is required for devices, hubs, or front panel connectors.

Advantages

This card delivers a single internal USB Type‑E (Key A) port with support for up to 20 Gbps data transfer, allowing faster connectivity for compatible devices. Its low profile form factor makes it suitable for small or compact cases, while the PCI Express x4 interface ensures compatibility with standard PCIe slots and stable bandwidth. The internal connector simplifies integration with internal hubs or front panel modules that accept a Type‑E Key A interface.

Suitable for

• Adding an internal high-speed USB 20 Gbps port to desktop PCs and compact workstations
• Connecting internal USB hubs, front panel USB modules, or SSDs that use an internal Type‑E (Key A) connector
• Systems with available PCIe x4 (or higher) slots requiring improved internal USB bandwidth

When it may not be suitable

This card provides a single internal USB Type‑E (Key A) port and is not a direct replacement for external USB ports on the rear I/O panel; external connectivity requires an appropriate internal-to-front-panel or cable solution. Systems without an available PCIe x4 (or larger) slot will be unable to use this card. Additionally, devices that require legacy USB signalling or lower-spec connectors may not be compatible with a 20 Gbps Type‑E interface.

Key specifications

• Interface: PCI Express x4 (card occupies a PCIe x4 slot)
• Internal port: 1 × USB Type‑E (Key A) internal connector
• Maximum data transfer rate: up to 20 Gbps
• Form factor: low profile (suitable for compact PC cases)
• Intended use: internal connection for devices, hubs, or front panel modules

How to use

Power down the PC and disconnect power before installation. Install the card into an available PCIe x4 or higher slot on the motherboard and secure it in the chassis using the appropriate bracket for the low profile form factor. Connect the internal Type‑E (Key A) cable or compatible internal device to the card’s internal port. Reassemble the case, restore power, and boot the system. The operating system should detect the new interface; install any necessary drivers provided by the OS or device manufacturer to ensure full functionality and optimal transfer rates.

What to consider before purchase

• Verify an available PCIe x4 (or larger) slot on the motherboard and sufficient internal space for a low profile card
• Confirm that the device or front panel you plan to connect supports an internal USB Type‑E (Key A) connector and 20 Gbps speeds
• Check operating system compatibility and whether additional drivers are required for your platform

Usage recommendations

For reliable high-speed transfers, use certified Type‑E internal cables and ensure your connected devices and hubs support the 20 Gbps specification. When installing in small form factor cases, confirm bracket type and clearance for proper mounting.
