The ASUS Prime AP303 is a compact 44-liter ATX chassis that accommodates 360mm radiators up to 60mm thick and graphics cards up to 360mm long. It features a graphics card bracket and holder to keep cards firmly mounted, plus an internal power cable that delivers 15 amperes to maintain stable power delivery for high-end PC builds.

Exceptional Space Efficiency

The AP303 is designed to maximize internal space, enabling installation of graphics cards up to 360mm long, radiators up to 360mm long and ATX power supplies up to 180mm long.

Superior Stability Under Heavy Loads

Alongside the graphics card holder is a graphics card bracket that supports GeForce RTX 50 Series graphics cards from 310mm to 360mm long. It securely mounts the graphics card with screws, reducing sagging and movement.

Efficient Cooling

With support for up to 360mm radiators and up to seven fans, the AP303 is primed to deal with the thermal scenarios of high-performance hardware.

Tool-Free Side Panels

The side panels of the AP303 use a simple but secure clip mechanism to attach to the case. This makes them easy to remove, providing easy access to the interior of the chassis.
