24-Core Ultra 9 Workstation

This Adamant Custom desktop pairs a 24-core Intel Core Ultra 9 285K with 192GB DDR5 and a 4TB NVMe drive. It targets professionals who need sustained multi-thread throughput for rendering, modelling or AI learning workloads. The 1200W 80 PLUS Gold supply and 360mm liquid cooler keep the platform stable under continuous load. Windows 11 Pro ships pre-installed.

Upgrade From Thread-Limited Systems

The jump makes sense when current hardware stalls on parallel compiles, large scene exports or model training batches that exceed available threads or memory. The 192GB ceiling removes the need for out-of-core workarounds, while the 4TB Samsung 990 PRO feeds data at up to 7450 MB/s read and 6900 MB/s write. Wi-Fi 7 and 2.5Gbps LAN keep network transfers from becoming the next bottleneck.

Suits Single-Box Studios

Studios that want one quiet mid-tower for compute and GPU acceleration will fit this build. Buyers who need more than 192GB RAM, additional GPU slots or a larger chassis for extra drive bays should look at something else. The fixed 360mm AIO and motherboard layout also limit custom loop expansion.

Questions about this item

Will a 360 mm radiator fit the mid-tower case?

The case measures 447 mm deep by 215 mm wide by 469 mm high and includes front mounts for two 140 mm fans, which is the standard layout for a 360 mm AIO radiator.

How do I seat the CPU into the LGA 1851 socket without bending pins?

Align the triangle marker on the Intel Core Ultra 9 285K with the socket corner, lower the processor straight down without force, then close the retention lever until it clicks.

When should I plan to replace the liquid-cooling fluid?

The 360 mm Quiet Edition AIO is a sealed unit; no fluid change is required, but dust the radiator fins and check pump noise every 12 months.
