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.

Quasi-Filter Mesh Panels

Metallic quasi-filter mesh panels are designed to enhance airflow and minimise dust ingress, delivering both performance and protection in a sleek style.

Pioneering Cable for High-End Systems

The UL-certified internal power cable delivers 15 amperes of current to ensure stable operation for high-end systems with a 1200W power supply.

USB Type-C® Support

AP303 includes one 20Gbps Type-C port and two USB 3.0 ports for future-ready and backward-compatible connectivity.

Unified Front I/O Header

A thoughtful header design makes connecting Front Input/Output (FIO) components to the motherboard easy.

Organised Cabling

A 34mm-wide compartment behind the motherboard provides ample space to neatly organise cables, despite the relatively compact dimensions of the chassis.
