Adamant Custom 20-Core Workstation

This Adamant Custom desktop pairs a 20-core Intel Core Ultra 7 265K with 192GB DDR5 and an Nvidia GeForce RTX 5090 32GB GPU. It targets professionals who need heavy rendering, modelling or AI learning capacity in a single Windows 11 Pro system. The 8TB NVMe array and 10TB HDD provide large local storage for active projects and archives.

240mm liquid cooler in a mid-tower case

A 240mm quiet-edition AIO cools the CPU while front and rear 140mm fans move air through the Ceres 300 chassis. The motherboard offers four memory slots, all populated, so any future RAM upgrade requires replacing existing modules. Only one 3.5-inch or two 2.5-inch drive bays remain free for additional SATA storage.

PCIe 4.0 SSD ceiling and Thunderbolt 4 bandwidth

The two Samsung 990 PRO drives top out at 7450 MB/s read and 6900 MB/s write on the PCIe 4.0 x4 interface. Thunderbolt 4 on the rear panel delivers 40 Gbps for external devices, while the 2.5 Gb Ethernet and Wi-Fi 7 2x2 handle network traffic. The 1000W 80 PLUS Gold PSU sets the power envelope for the complete build.

Questions about this item

How can I confirm the Intel Core Ultra 7 265K is running at its 5.50 GHz boost clock after setup?

Open Windows Task Manager, select the Performance tab, and watch the CPU frequency while running a heavy render or compile job; it should climb toward 5.50 GHz when thermals allow.

Which components are pre-installed and which must be purchased separately for this workstation?

The case, 1000W 80 PLUS Gold PSU, Z890 motherboard, 240 mm liquid cooler, 20-core Ultra 7 265K, 192 GB DDR5, two 4 TB Samsung 990 PRO SSDs, 10 TB HDD, RTX 5090 32 GB GPU, Windows 11 Pro, Wi-Fi 7 and Bluetooth 5.4 are all included; only a monitor, keyboard and mouse need buying separately.

Should I choose the 192 GB DDR5 configuration or a lower capacity for AI modelling workloads?

The board supports a maximum of 192 GB across four slots and this build already populates that limit, so the 192 GB option is the only one that delivers full capacity for large-model training without later upgrades.
