Perfect Clearance Achieved
The NVIDIA GeForce RTX 4090 (304.0mm) easily clears the Phanteks NV5's 440.0mm maximum GPU length.
Detailed Compatibility Analysis
Will the NVIDIA GeForce RTX 4090 fit inside a Phanteks NV5?
Yes, it fits! The NVIDIA GeForce RTX 4090 comes in at 304.0mm long, leaving plenty of room inside the Phanteks NV5 (which supports up to 440.0mm).
Clearance and Airflow
With this specific hardware combination, you are left with exactly 136.0mm of physical space between the front edge of the GPU and the front panel (or front fans). This is a healthy amount of breathing room, ensuring your graphics card stays cool and airflow remains unrestricted.
Installation Tips
When installing a card of this size, always double-check your front panel cooling setup. If you plan to install a thick front-mounted AIO liquid cooler radiator in the Phanteks NV5, you must subtract the radiator's thickness (usually 27-30mm) from your 136.0mm remaining space.
Frequently Asked Questions
Does the Phanteks NV5 support vertical GPU mounting?
Many modern cases support vertical mounting via an optional PCIe riser cable. However, mounting a thick card like the NVIDIA GeForce RTX 4090 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 NVIDIA GeForce RTX 4090?
You should refer to the official manufacturer recommended PSU wattage. When building in the Phanteks NV5, 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 NV5, you must subtract the thickness of the radiator (usually 27mm) and the fans (usually 25mm) from the total 440.0mm clearance.
