24-Core Ultra 9 Workstation

The Adamant Custom desktop pairs a 24-core Intel Core Ultra 9 285K processor with 128GB DDR5 memory and an Nvidia GeForce RTX 5070 Ti 16GB graphics card. It ships with Windows 11 Pro on a 1TB Samsung 990 PRO PCIe 4.0x4 SSD. The system targets rendering, editing, modelling and AI learning workloads in a tower form factor.

Installation and common issues

The PC arrives fully assembled with a 360mm AIO liquid cooler mounted to the LGA 1851 socket and a Thermaltake Smart 850W 80 PLUS Bronze power supply connected. Builders should verify that the cooler block is seated evenly and that all GPU power cables are fully latched. The Ceres 300 case provides front USB 3.2 Gen 2 Type-C and two USB 3.0 ports alongside rear Thunderbolt 4 and multiple USB 20Gbps and 10Gbps connections.

Practical limits of the platform

The Z890 motherboard supports up to 192GB DDR5 across four slots and offers four M.2 connectors plus four SATA 6Gbps ports for additional NVMe or SATA storage. Rear networking includes Intel 2.5Gb Ethernet, Wi-Fi 7 2x2 and Bluetooth 5.4. The 850W Bronze-rated PSU caps sustained power delivery, so further high-wattage upgrades may require a larger supply.

Questions about this item

How do I confirm the 360 mm liquid cooler is keeping the 24-core Ultra 9 285K at its 5.70 GHz boost?

Watch the CPU temperature in the BIOS hardware monitor or a Windows utility; the 360 mm AIO should hold the 24-core chip well below its thermal limit while the 5.70 GHz boost is active.

What ships inside the Ceres 300 case and which parts must I add myself?

The tower arrives fully assembled with the Z890 TUF motherboard, 128 GB DDR5, 1 TB Samsung 990 PRO NVMe, RTX 5070 Ti 16 GB, 850 W Thermaltake PSU, 360 mm AIO, Windows 11 Pro and front 2 × 140 mm plus rear 140 mm fans; only a display, keyboard and mouse are needed separately.

Which capacity of the Samsung 990 PRO should I choose for this Z890 build?

The system includes the 1 TB model rated at 7450 MB/s read and 6900 MB/s write; the board provides four M.2 slots so additional NVMe drives can be added later if more space is required.
