20-Core Ultra 7 Workstation

The Adamant Custom desktop pairs a 20-core Intel Core Ultra 7 265K processor with 64GB DDR5 memory and an Nvidia GeForce RTX 5090 32GB graphics card. It targets professionals who need AI-ready compute for rendering, modelling and machine-learning workloads alongside high-refresh gaming. The system ships with Windows 11 Pro on an 8TB NVMe array built from two 4TB Samsung 990 PRO drives.

PCIe 4.0 storage ceiling

Sequential reads reach 7450 MB/s and writes 6900 MB/s on the PCIe 4.0x4 interface used by the installed SSDs. The Z890 motherboard provides four M.2 connectors, yet only two are populated, so total capacity can grow without sacrificing the current throughput. Rear I/O includes Thunderbolt 4, USB 20Gbps and USB 10Gbps ports for external expansion.

1000W Gold power headroom

A Thermaltake Toughpower 1000W 80 PLUS Gold unit with Japanese main capacitors powers the 240mm liquid CPU cooler, dual 140mm case fans and the RTX 5090. The 1000W rating leaves margin for future GPU upgrades that draw more than the current card. Builders who need more than 192GB RAM or additional 3.5-inch drive bays should verify the four-slot memory limit and single 3.5-inch bay before committing.

Questions about this item

Should I choose the 64 GB DDR5 configuration or upgrade to the 192 GB maximum supported?

The system ships with 64 GB DDR5 across four slots. The motherboard supports up to 192 GB total, so you can add modules later if workloads such as large-scale rendering or AI training need more capacity.

What does the 5.50 GHz maximum turbo frequency mean for actual gaming and creative work?

The 20-core Intel Core Ultra 7 265K can boost up to 5.50 GHz on active cores, giving high single-thread speed for game engines and responsive timeline scrubbing in editing apps while the 30 MB L3 cache keeps data close.

How fast are the Samsung 990 PRO drives over the PCIe 4.0 x4 interface in this build?

Each 4 TB drive delivers up to 7450 MB/s read and 6900 MB/s write over PCIe 4.0 x4, so the paired 8 TB array loads massive project files and game assets at near-peak interface throughput.
