Hardware Conflict Detected
The ASUS TUF Gaming RTX 4080 Super (339.0mm) exceeds the Corsair 280X's 300.0mm maximum GPU length.
Detailed Compatibility Analysis
Will the ASUS TUF Gaming RTX 4080 Super fit inside a Corsair 280X?
Unfortunately, the ASUS TUF Gaming RTX 4080 Super will not fit inside the Corsair 280X. The 339.0mm card is physically too large for the 300.0mm chassis.
The Physical Problem
Because the graphics card exceeds the case limitations by 39.0mm, it is physically impossible to close the side panel or slot the card into the PCIe lane without removing critical chassis components from the Corsair 280X.
Next Steps
Do not attempt to modify the Corsair 280X with a Dremel. It is highly recommended to select a different chassis with at least 354.0mm of total clearance to allow for proper cable routing.
Frequently Asked Questions
Does the Corsair 280X support vertical GPU mounting?
Many modern cases support vertical mounting via an optional PCIe riser cable. However, mounting a thick card like the ASUS TUF Gaming RTX 4080 Super vertically can push the fans dangerously close to the glass side panel, choking airflow. Always check the case manual for specific slot spacing.
What power supply (PSU) do I need for the ASUS TUF Gaming RTX 4080 Super?
You should refer to the official manufacturer recommended PSU wattage. When building in the Corsair 280X, ensure your PSU is not longer than the case's basement shroud clearance, especially if you plan to keep the hard drive cage installed.
How do I calculate clearance if I add a front liquid cooler?
If you install an AIO liquid cooler in the front of the Corsair 280X, you must subtract the thickness of the radiator (usually 27mm) and the fans (usually 25mm) from the total 300.0mm clearance.
