24-Core Ultra 9 Workstation

This Adamant Custom desktop pairs a 24-core Intel Core Ultra 9 285K processor with 192GB DDR5 memory and an Nvidia GeForce RTX 5090 32GB graphics card. The tower chassis uses liquid cooling and a 1200W 80 PLUS Gold power supply. It targets professionals who need high multi-thread throughput for rendering, modelling and AI learning workloads alongside high-end gaming capability.

Upgrade From Thread-Limited Systems

The configuration replaces workstations that stall on core count or VRAM when handling large scenes, heavy simulation or local model inference. The jump is worth it when 24 cores and 32GB GPU memory remove the bottlenecks that force batch splitting or cloud offload. Two 4TB Samsung 990 PRO drives in RAID 0 deliver up to 7450 MB/s read and 6900 MB/s write for asset streaming.

PCIe 4.0 and 2.5GbE Ceilings

Storage and rear I/O top out at PCIe 4.0 x4 lanes, so newer PCIe 5.0 drives will not run at their rated speed. The integrated 2.5Gbps Ethernet port caps wired network throughput below 10GbE infrastructure. Wi-Fi 7 and Bluetooth 5.4 provide modern wireless connectivity, while Thunderbolt 4 and multiple USB 20Gbps and 10Gbps ports handle high-speed peripherals.

Questions about this item

What clearance does the 360 mm liquid cooler need inside the Ceres 300 case?

The Ceres 300 mid-tower measures 475 x 245 x 463 mm and is built to house a 360 mm radiator; verify the front panel accepts a 360 mm unit before mounting.

Which motherboard power connectors must be seated for the Intel Core Ultra 9 285K and RTX 5090?

Connect the 24-pin ATX cable, the CPU 8-pin (or 8+4-pin) EPS cable to the Z890 TUF board, and the GPU 12VHPWR cable from the 1200 W PSU to the RTX 5090.

When should the 140 mm case fans or the AIO pump be checked or replaced?

Front and rear 140 mm fans run at 1500 rpm; inspect bearings and clean dust every 12 months, and watch the 360 mm AIO pump for noise or temperature rise that signals wear.
