24-Core AI Workstation

This Adamant Custom tower pairs a 24-core Intel Core Ultra 9 285K processor with 192GB of DDR5 memory and an Nvidia GeForce RTX 5090 32GB graphics card. It is built for professionals running rendering, modelling and AI learning workloads that demand high thread counts and large video memory. The system ships with Windows 11 Pro installed and ready to use.

Z890 Platform Connectivity

The Gigabyte Z890 UD motherboard provides rear USB4 Type-C, USB 3.2 Gen 2 and multiple USB 3.2 Gen 1 ports alongside 2.5Gb Ethernet, Wi-Fi 6E and Bluetooth5.3. Internal headers add a front-panel USB Type-C connection and additional USB 2.0 ports. Four SATA ports support RAID 0, 1, 5 or 10 arrays while four M.2 slots are populated by the included storage. A 1200W 80 PLUS Gold power supply delivers protected, low-noise power to every component.

8TB NVMe Storage Headroom

Two Samsung 990 PRO 4TB drives provide 8TB of PCIe 4.0x4 NVMe capacity with sequential reads up to 7450 MB/sec and writes up to 6900 MB/sec. This volume handles large project libraries, model weights and scratch files without requiring external arrays. The 192GB DDR5 ceiling matches the board maximum so memory cannot be expanded further. The 360mm liquid cooler keeps the 24-core CPU within thermal limits during sustained compute tasks.

Questions about this item

Will the 360mm liquid cooler keep the 24-core Ultra 9 285K at its 5.70 GHz boost during long renders?

The 360mm Quiet Edition AIO is designed for the 285K’s thermal envelope; sustained all-core loads will run at the rated 3.7 GHz base with turbo up to 5.70 GHz while coolant temperatures stay within spec.

How loud is the Thermaltake 1200W Gold PSU fan when the RTX 5090 and CPU are both at full load?

The PSU uses a 140mm ultra-quiet fan that spins slowly under typical loads; at combined GPU and CPU maximum draw the fan ramps up but remains within the unit’s low-noise rating.

Does the Corsair 4000D case come with the monitor cable I need for the RTX 5090?

No display cable is included; you must supply a DisplayPort or HDMI cable that matches your monitor’s input.
