Which GPU support brackets are compatible with the Antec Flux Pro Noctua Edition?

Our testing shows that the main constraint when installing a GPU support bracket in the Antec Flux Pro Noctua Edition case is the two bottom fans mounted on the PSU shroud. To ensure a good fit and maintain optimal airflow, choose a stand that meets these criteria:

  • A compact base, so that it can fit either between the bottom fans and the case side panel or on top of the fan frames.
  • A streamlined design free from bulky appendages that could create audible airflow turbulence.

Horizontal GPU support bars

These bars mount directly into the PCIe bracket slots at the rear of the case. This method offers excellent stability and is generally compatible with the Antec Flux Pro Noctua Edition without modification. 

Please note general height restrictions. For example, with an ASUS GeForce RTX 5080 Noctua Edition installed, there’s about 45mm of space between the GPU and the fans installed on top of the PSU shroud.

Height-adjustable vertical brackets

These braces attach to the mounting holes of the intake fans on the PSU shroud cover and tend to work well with the Antec Flux Pro Noctua Edition. 

Brackets with a base stand 

Note these restrictions when using a GPU stand that rests on the fans above the PSU shroud cover: 

  • Base diameter: Must be under 15mm. This ensures the stand balances securely on the fan frames without obstructing airflow.
  • Height adjustment: For thick, triple-slot or quad-slot cards (e.g., the ASUS GeForce RTX 5080 Noctua Edition), the stand must be adjustable down to a height of45mm at most. 
    Note: The stand included with Noctua Edition ASUS graphics cards fits perfectly at its lowest setting, see photo above. For other GPU models, please verify the required height based on your specific card's thickness.
  • Arm design: If the brace includes a horizontal arm for the GPU to rest on, ensure it is not overly bulky to prevent airflow turbulence. Additionally, verify that the arm is long enough to reach the GPU once installed.
