24-Core AI Workstation

The Adamant Custom desktop pairs a 24-core Intel Core Ultra 9 285K processor with 128GB of DDR5 memory and an 8TB NVMe array built from two 4TB Samsung 990 PRO drives. An Nvidia GeForce RTX 5070 with 12GB of video memory handles graphics and compute workloads. The system ships with Windows 11 Pro and targets creators and engineers who need high multi-thread throughput and large local storage in a single tower.

360mm Liquid Cooling and 850W Bronze PSU

A 360mm quiet-edition all-in-one cooler manages CPU thermals while front-mounted 140mm PWM fans move air through the tempered-glass chassis. The Thermaltake Smart 850W 80 PLUS Bronze supply uses a Japanese main capacitor and delivers over-voltage, under-voltage, over-power and short-circuit protection. Acoustic output stays low under typical mixed workloads thanks to the liquid loop and low-noise fan profile.

Z890 Connectivity and Expansion Bays

The Gigabyte Z890 Eagle motherboard provides Wi-Fi 7 and Bluetooth 5.4 alongside Intel 2.5Gb Ethernet. Rear I/O includes one USB4 Type-C, two USB 3.2 Gen 2, three USB 3.2 Gen 1 and four USB 2.0 ports; the front panel adds one USB 3.2 Gen 2x2 Type-C, two USB 3.0 and dual audio jacks. Internal bays accept two 3.5-inch and two 2.5-inch drives, while four M.2 slots and four SATA 6Gb/s ports with RAID 0, 1, 5, 10 support remain available for future storage growth.

Questions about this item

How is the 360 mm liquid cooler installed, and what step is often missed?

The 360 mm AIO mounts to the top of the tower case using the included radiator brackets and fans; the step many builders miss is removing the protective film from the cold-plate before seating it on the Core Ultra 9 285K LGA 1851 socket.

What maintenance or replacement will the cooling system need later?

The sealed 360 mm Quiet Edition loop requires no fluid changes; only the three 140 mm PWM fans may need dust cleaning or eventual replacement after several years of continuous operation.

What limit appears first during sustained heavy workloads?

The Thermaltake Smart 850 W 80 PLUS Bronze PSU sets the sustained power ceiling, so total system draw cannot exceed 850 W without triggering over-power protection.
