Detailed Compatibility Analysis
Will the ASUS TUF Gaming RTX 4080 Super fit inside a Phanteks Eclipse G360A RGB?
If you are planning a build with the ASUS TUF Gaming RTX 4080 Super and the Phanteks Eclipse G360A RGB, you are in luck. The math checks out: Yes, it fits perfectly. The 400.0mm clearance easily accommodates the 339.0mm graphics card.

Build Advice
Since the ASUS TUF Gaming RTX 4080 Super is a heavy piece of hardware, we highly recommend using a GPU anti-sag bracket. Even though it clears the Phanteks Eclipse G360A RGB length-wise, PCIe slot sag is a real threat to your motherboard over time.
Frequently Asked Questions
Does the Phanteks Eclipse G360A RGB 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 Phanteks Eclipse G360A RGB, 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 Phanteks Eclipse G360A RGB, you must subtract the thickness of the radiator (usually 27mm) and the fans (usually 25mm) from the total 400.0mm clearance.
