24-Core Intel Core Ultra 9 Workstation

This Adamant Custom tower pairs a 24-core Intel Core Ultra 9 285K processor with 64GB of DDR5 memory and an 8TB NVMe array built from two Samsung 990 PRO drives. A GeForce RTX 5070 graphics card and a 360mm liquid cooler complete a system assembled for creators and engineers who need sustained multi-thread throughput. Windows 11 Pro is installed and the platform supports up to 192GB of memory across four slots.

Upgrade From 8-Core Or Air-Cooled Builds

Moving from an 8-core desktop or an air-cooled chassis removes the thermal ceiling that throttles long renders, compiles or simulation jobs. The 360mm liquid loop keeps the 285K at high frequencies while the 850W 80 PLUS Bronze supply delivers stable power for the GPU and storage subsystem. The jump is worth it when single-thread bursts are no longer the bottleneck and sustained all-core performance determines project turnaround.

Sustained Load With Liquid Cooling

Under continuous multi-thread load the 360mm quiet-edition cooler maintains lower coolant temperatures than typical air towers, allowing the CPU to hold elevated boost clocks for the duration of a workload. The RTX 5070 12GB and dual PCIe 4.0 NVMe drives feed data without stalling, while the Z890 motherboard provides Wi-Fi 7 and Bluetooth5.4 connectivity for remote monitoring. Thermal headroom stays consistent hour after hour.

Questions about this item

What case clearance and mounting points does the 360 mm liquid cooler require?

The 360 mm AIO fits the tower case with 447 mm depth, 215 mm width and 469 mm height; it mounts to the standard 140 mm fan locations on the front or top panel.

Which motherboard power connectors must be seated for the Intel Core Ultra 9 285K on the Z890M AORUS board?

Insert the 24-pin ATX cable and the 8-pin EPS connector into the LGA 1851 socket area; the 850 W Thermaltake unit supplies both.

How many M.2 slots remain free after the two 4 TB Samsung 990 PRO drives are installed?

The Z890M AORUS provides three M.2 connectors; two are occupied by the factory SSDs, leaving one open for future NVMe expansion.
