Adamant Custom 20-Core Ultra 7 265K Z890 TUF 128GB DDR5 1TB NVMe RTX 5070 Gaming PC

20-Core AI Workstation

This desktop combines a 20-core Intel Core Ultra 7 265K processor with 128GB of DDR5 memory and an Nvidia GeForce RTX 5070 graphics card. It is built for professionals who need local compute for rendering, modelling and AI learning workloads alongside high-refresh gaming. The system ships with Windows 11 Pro and a 1TB Samsung 990 PRO NVMe drive. Liquid cooling keeps the CPU stable under sustained multi-threaded loads.

Z890 Platform Requirements

The motherboard uses the LGA 1851 socket and Z890 chipset, so any future processor upgrade must match that socket. Four DDR5 slots are populated to reach 128GB, leaving no free slots for expansion without removing modules. The 750W 80 PLUS Bronze power supply delivers a fixed output ceiling for the current GPU and CPU combination. The Corsair 4000D case provides two 3.5-inch and two 2.5-inch internal drive bays for additional storage.

Upgrade Path Considerations

This configuration replaces a system limited to 64GB of memory or a previous-generation GPU with less than 12GB of VRAM. The jump is worthwhile when workflows exceed 64GB RAM or require the RTX 5070 feature set for local inference and real-time viewport performance. Builders who need a second graphics card or more than four M.2 drives should look at a larger chassis and higher-wattage platform.
