ArsenalPC AP202 Ryzen 9 9900X RTX 5090 128GB 4TB liquid gaming PC

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.
