Hello Razer Support,

 

I need your help with a compatibility issue regarding my Razer Core X V2 (Serial Number: 612531U44000179).

 

Equipment:

 

  • MacBook Pro 16-inch (2019, Model A2141) — i9, Radeon Pro 5600M, 64GB RAM, running both macOS (Sequoia/Sonoma) and Windows 10 (Boot Camp)

  • Razer Core X V2 (Thunderbolt 3/5, S/N: 612531U44000179)

  • Sapphire PULSE RX 7900 XTX 24GB (SKU: 11322-02-20G)

 

 

Issue:

 

  • In Windows (Boot Camp): The RX 7900 XTX is not detected at all (not visible in Device Manager, no unknown devices appear when eGPU is connected, no output to external monitor via GPU).

  • In macOS: The Razer Core X V2 enclosure is detected as a Thunderbolt device in System Information, but the RX 7900 XTX does not show up under PCI or Graphics, and no video output is available via eGPU.

  • All required cables are connected: three PCIe 8-pin cables to the GPU, 24-pin and 8-pin EPS to the enclosure board.

  • The RX 7900 XTX is fully functional and has been tested on a standard PC (it works perfectly there).

  • I have tried both official AMD Adrenalin drivers and modified BootCampDrivers.com packages.

  • The enclosure powers on, the Thunderbolt connection is recognized by the Mac, but the GPU itself never appears in software or outputs a signal.

 

 

Steps already taken:

 

  • Full power cycle, reconnecting all cables, tried different Thunderbolt ports.

  • Verified power supply (Corsair RM850x) — all cables seated, PSU is functional.

  • Reinserted GPU several times to rule out poor PCIe connection.

  • Tried with and without the 8-pin EPS cable to the enclosure board.

  • Reset SMC/NVRAM on MacBook, tested on clean installs of Windows and macOS.

  • The same results regardless of the OS or drivers used.

 

 

Questions:

 

  1. Is the Razer Core X V2 officially compatible with AMD RX 7900 XTX series cards?

  2. Are there any firmware updates or hardware revisions required for proper support of the RX 7900 XTX?

  3. Does the enclosure require a specific cable/connection for high-end cards like RX 7900 XTX?

  4. Are there any known issues with Thunderbolt on MacBook Pro 16,1 (A2141) and this eGPU?

  5. Can you provide any troubleshooting steps or configuration settings that are required for this setup?

 

 

Any advice, official comments, or documentation would be very helpful.

Thank you in advance for your time.

 

Best regards
