ArsenalPC ASUS Prime AP202 Ryzen 7 9800X3D RTX 5090 128GB DDR5 4TB NVMe Liquid Cooled White gaming PC

System identity

The ArsenalPC ASUS Prime AP202 is a complete gaming desktop built around a 16-core Ryzen 7 9800X3D processor running at 4.7GHz. It pairs that CPU with an RTX 5090 graphics card using GDDR7 memory, 128GB of DDR5 in four 32GB modules and a 4TB NVMe drive. Liquid cooling and a 1200W supply support sustained loads for creators and enthusiasts who want a ready-to-run white chassis.

Upgrade path

This configuration replaces a mid-range tower that relies on air cooling and a lower-tier GPU when workloads demand 96MB of L3 cache, 2.5G Ethernet and 128GB of memory for large datasets. The jump is worth it when projects exceed the VRAM or thread count of a previous build and when Windows 11 stability on AM5 is required from day one. Buyers who need multiple GPU slots or a smaller footprint should look elsewhere.

Platform limits

The AM5 platform used here supports DDR5 288-pin modules and a 360mm liquid cooler with an integrated LCD, but the motherboard layout fixes the number of memory slots at four and the power delivery at 1200W. No additional drive bays or PCIe lanes beyond what the chipset provides are available inside the AP202 case. Expandability beyond the factory specification is therefore constrained by the board and chassis design.
