ASUS has announced its new ASUS Prime AP303 case, designed for high-performance computer components. With its compact 44-liter capacity, it saves space while accommodating even the most powerful hardware, offering an ideal solution for users seeking both aesthetics and functionality. It particularly stands out for its full support of next-generation massive graphics cards and advanced cooling systems.
What are the ASUS Prime AP303 Case Features?
The new ASUS Prime AP303 stands out with its spacious interior despite its small size. ASUS has considered every detail to ensure users can seamlessly utilize the latest and most powerful components, maximizing capacity in this case. The basic hardware support offered by the case positions it as a strong contender in its segment.

Graphics Card Support: Graphics cards up to 360 mm in length (including NVIDIA GeForce RTX 50 Series).
Liquid Cooling Support: 360 mm radiators up to 60 mm thick.
Power Supply (PSU) Support: ATX power supplies up to 180mm in length.
However, the case comes with a dedicated support slot to prevent sagging or wobbling of heavy graphics cards, especially those like the ROG Astral GeForce RTX 5090. This ensures the long-term stability of your system. Additionally, the UL-certified internal power cable promises stable operation with 15 amps of current support.
The ASUS Prime AP303 features a semi-filtered metallic mesh design to maximize cooling performance. This special structure maximizes airflow, keeping components cool at all times. With a total of seven fan mounting points, the case helps maintain your system’s performance even under the heaviest load.
Prioritizing user experience, ASUS uses a tool-free side panel design in the AP303 model. Users can choose between tempered glass to showcase the inside of their system or a metallic mesh side panel for maximum airflow. Available in black and white, the case’s internal cabling also offers an aesthetic that complements the exterior color.
Modern connectivity needs haven’t been forgotten either. The front panel of the case features one USB 20 Gbps Type-C port for high-speed data transfer, two USB Type-A ports, and headphone/microphone jacks. This makes connecting peripherals extremely easy.
