eGPU adapter ADT-UT3G PCIe 3.0 x16 USB4 | Thunderbolt macOS, Windows 40 Gb/s

The ADT-UT3G is a PCIe 3.0 x16 to USB4 or Thunderbolt adapter to connect, for example, a high-speed external graphics card to a PC with a USB4 or Thunderbolt connector or another PCIe card to a mac or PC with a USB4 or Thunderbolt connector.

With this ADT-UT3G adapter, you will connect a Windows PC with USB 4 or Thunderbolt ports:

• a high-speed external graphics card, and 

to macOS and Windows PCs:

• high-speed external network card - e.g. 2x 10GbE, 2x 25GbE, 2x 40GbE
• SAS, SATA or NVMe controller
• RAID controller
• video capture or editing card
• audio capture or editing card
• and other PCIe cards 

The data transfer rate between the PCIe connector and USB 4 | Thunderbolt is max. 40 Gbps

For correct operation of the adapter, an external ATX power supply with a wattage compatible or higher with the PCIe card to be installed is required - the power supply is not included.
