ArsenalPC MSI GUNGNIR 110R Ryzen 9 9900X RTX 5090 128GB DDR5 2TB NVMe Liquid Cooled Gaming PC

Built for 4K and AI workloads

This ArsenalPC desktop pairs a 12-core Ryzen 9 9900X processor running at 4.4 GHz with an RTX 5090 graphics card equipped with 32 GB of GDDR7 memory. The platform targets enthusiasts who need high frame rates at 4K resolution and developers running local AI models that demand large video memory. A 1200 W power supply and 240 mm liquid cooler support sustained operation of both components.

Pre-built with standard ATX layout

The system arrives fully assembled inside the MSI GUNGNIR 110R case with Windows 11 Home installed. Memory uses 288-pin DDR5 DIMMs totalling 128 GB, while storage is handled by a 2 TB NVMe SSD. Builders should verify case clearance for future GPU upgrades and ensure the motherboard’s AM5 socket matches any planned CPU changes. Integrated audio and 2.5G Ethernet handle baseline connectivity.

Liquid cooling manages prolonged sessions

The 240 mm liquid cooler keeps the 12-core processor at stable temperatures during extended rendering or gaming sessions, avoiding the throttle points common with air coolers under continuous load. The 1200 W unit delivers consistent power to the RTX 5090 and CPU without voltage droop. RGB lighting adds visual feedback but does not affect thermal performance.
