24-Core Workstation for AI and Content Creation

This Adamant Custom desktop pairs a 24-core Intel Core Ultra 9 285K processor with 192GB of DDR5 memory and a 4TB Samsung 990 PRO NVMe drive. The system targets professionals who need high multi-threaded throughput for rendering, compilation or local AI inference without a discrete graphics card. Integrated graphics handle display output through HDMI and DisplayPort. The Z890 TUF motherboard provides Thunderbolt, USB 20Gbps and Wi-Fi 7 connectivity for fast peripherals and networking.

Sustained Load Behaviour with 360mm Liquid Cooling

A 360mm quiet-edition AIO cooler manages the CPU thermal envelope during prolonged workloads, while front and rear 140mm case fans rated at 1500rpm and 30dBA maintain chassis airflow. The Thermaltake Smart 850W 80 PLUS Bronze power supply includes over-voltage, under-voltage, over-power and short-circuit protection. With the CPU capable of reaching 5.70 GHz boost clocks and 36MB L3 cache, the cooling solution is designed to sustain elevated frequencies across all 24 cores without thermal throttling.

Compatibility Checks Before Ordering

Verify that the Ceres 300 mid-tower dimensions of 475 x 245 x 463 mm fit your allocated space and that the single 3.5-inch or dual 2.5-inch drive bay arrangement meets any additional storage plans. The motherboard offers four M.2 slots and four SATA 6Gb/s ports, so confirm lane allocation if you intend to add further NVMe or SATA drives. Rear I/O includes one Thunderbolt 4 Type-C, one USB 20Gbps Type-C, three USB 10Gbps and three USB 5Gbps ports; ensure your peripherals match these interfaces. The system ships with Windows 11 Pro 64-bit installed.
