  • 12-core Ryzen 9 9900X at 4.4 GHz for heavy multitasking
  • RTX 5090 with GDDR7 memory for high-resolution gaming

Core specification

This system pairs a 12-core Ryzen 9 9900X processor at 4.4GHz with an RTX 5090 graphics card featuring GDDR7 memory. It is configured with 128GB of DDR5 RAM across four 32GB modules and a 4TB SSD for storage. The build targets users who need maximum local compute for AI inference, rendering or high-refresh gaming. It is not suited for buyers who want a smaller chassis or a lower power draw.

Interface limits

The motherboard uses the AMD AM5 platform with 288-pin DDR5 slots populated by the four included modules. Network connectivity includes 2.5G Ethernet and a wireless card, while the 1200W power supply delivers energy to all components. Expanding memory beyond the installed 128GB would require replacing existing modules because all slots are occupied. Builders who need additional drive bays or a second graphics card should verify case clearance before purchase.

Build and daily use

The AP202 case houses a 360mm liquid cooler with an integrated LCD panel alongside RGB lighting throughout. Liquid cooling manages thermals for the high-wattage CPU and GPU combination under sustained loads. The white finish and lighting effects are visible through the chassis panels. Users who prefer a quieter air-cooled setup or a more compact footprint will find this configuration less appropriate.

Questions about this item

How do I choose between the 128 GB DDR5 kit and a smaller capacity?

The system ships with 128 GB as four 32 GB DDR5 modules filling all 288-pin slots; a smaller kit would leave empty slots and reduce total capacity.

What does the Ryzen 9 9900X 4.4 GHz figure mean in daily use?

The 12-core processor runs at a 4.4 GHz base clock, giving strong multi-threaded performance for gaming, rendering and local AI inference.

What does the 2.5 G Ethernet port cap at in practice?

The onboard 2.5 G Ethernet controller limits wired throughput to 2.5 Gbps, so transfers will not exceed that speed even with faster switches.
