24-Core Liquid Cooled Desktop

The Adamant Custom tower ships new with a 24-core Intel Core Ultra 9 285K processor, 64GB of DDR5 memory and a 1TB NVMe SSD. A 360mm liquid cooler handles the CPU while an RTX 5070 graphics card with 12GB drives the display. Windows 11 Pro is installed on the Z890 TUF motherboard.

Creative Workstations And High-Refresh Gaming

The combination of 24 threads, 64GB RAM and a 12GB RTX 5070 suits 4K editing, 3D rendering and high-refresh competitive play. Buyers who need more than 1TB of primary storage or a second graphics card should look elsewhere. The four memory slots allow expansion to 192GB if workloads grow.

360mm Liquid CPU Cooler

A 360mm quiet-edition AIO cooler is the single spec that determines whether this chassis fits the thermal envelope of the 285K. The loop is pre-filled and sealed, so no maintenance is required. If the case clearance or radiator mounting points differ from the Ceres 300 layout, the cooler will not install.

Questions about this item

Will the 360 mm liquid cooler and Ceres 300 case fit on my desk?

The Ceres 300 mid-tower measures 475 mm deep, 245 mm wide and 463 mm high; the 360 mm AIO mounts at the front with two 140 mm fans, so allow at least 475 mm depth plus cable clearance.

What is the correct order to seat the Core Ultra 9 285K into the LGA 1851 socket on the Z890 TUF board?

Lift the socket lever, align the CPU triangle with the socket corner, lower the chip without force, close the lever, then attach the 360 mm AIO block using the supplied LGA 1851 bracket and tighten the four screws in a cross pattern.

Which components can I upgrade later without replacing the power supply?

The Thermaltake Smart 850 W 80 PLUS Bronze unit supports the existing RTX 5070 and 24-core CPU with headroom for a second 1 TB NVMe drive, up to 192 GB DDR5 across four slots, and additional 2.5-inch SSDs in the drive bay.
