Adamant Custom EAGLE Workstation

The Adamant Custom EAGLE is a tower workstation built around a 24-core Intel Core Ultra 9 285K processor and an Nvidia GeForce RTX 5080 graphics card with 16GB memory. It targets professionals in rendering, editing, modelling and AI learning who need high multi-threaded compute and GPU acceleration in a single system. Windows 11 Pro is pre-installed.

360mm Liquid Cooling and 1000W PSU

A 360mm quiet-edition AIO liquid cooler handles the CPU thermal load while front-mounted 140mm PWM fans move air through the tempered-glass case. The Thermaltake Toughpower 1000W 80 PLUS Gold supply uses Japanese main capacitors and a low-noise 140mm fan, delivering stable power with over-voltage, under-voltage, over-power and short-circuit protection.

Z890 Platform with Wi-Fi 7

The Gigabyte Z890 EAGLE motherboard provides LGA 1851 socket support, four DDR5 slots populated with 64GB and room to reach 192GB, plus four M.2 connectors — two filled by 4TB Samsung 990 PRO PCIe 4.0 drives. Rear I/O includes USB4 Type-C, USB 3.2 Gen 2x2 Type-C on the front panel, Intel 2.5Gb Ethernet, Wi-Fi 7 and Bluetooth 5.4. Internal bays allow additional 3.5-inch or 2.5-inch drives.

Questions about this item

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

The 360mm AIO cooler arrives pre-fitted to the Intel Core Ultra 9 285K on the GIGABYTE Z890 EAGLE motherboard; the step people miss is connecting the pump header and the PWM fan cables to the correct CPU_FAN and AIO_PUMP headers so the cooler reports speed to the BIOS.

What maintenance or replacement will the liquid cooler need later?

The sealed 360mm AIO loop requires no coolant top-ups; after several years the pump may wear or the radiator fins collect dust, so plan to clean the three 140mm fans and, if temperatures rise, replace the whole AIO unit.

What limit appears first during sustained heavy loads?

Under continuous full-core and GPU load the 1000W 80 PLUS Gold PSU will hit its 1000W output ceiling before the CPU reaches its 5.70 GHz turbo or the RTX 5080 16GB hits its thermal limit.
