Core Ultra 9 285K desktop

This ArsenalPC gaming desktop centres on an Intel Core Ultra 9 285K processor with 24 cores running at 5.7GHz. It is built for users who need maximum multi-thread throughput for gaming, streaming and heavy content creation in a single Windows 11 Home system. The LGA 1851 platform supports 64-bit computing with headroom for demanding workloads.

Gigabyte C301 GLASS chassis

The mid-tower case uses tempered glass panels and a 240mm liquid cooler to manage CPU thermals while showcasing internal RGB lighting. A 1000W power supply feeds the GeForce RTX 5080 graphics card with 16GB GDDR7 memory over a PCI Express x16 link. Four DDR5 slots are fully populated with 128GB total capacity, leaving no free DIMM positions for later expansion.

RTX 5080 16GB GDDR7 limits

The graphics card delivers virtual-reality-ready performance but its 16GB frame buffer caps texture and asset loads at 4K and above. The single 2TB NVMe SSD provides fast boot and game launch speeds yet offers no secondary drive bay mentioned for bulk storage. Buyers who want more storage or a second GPU will need to verify case and motherboard clearance themselves.
