Adamant Custom Core Ultra 9 285K RTX 5080

This gaming desktop PC ships with a 24-core Intel Core Ultra 9 285K processor and an Nvidia GeForce RTX 5080 graphics card. It includes 64GB of DDR5 memory and a 4TB Samsung 990 PRO NVMe SSD. A 360mm liquid cooler and 1000W 80 PLUS Gold power supply support the high-performance components. Windows 11 Pro comes pre-installed.

Suits 24-core rendering and AI workloads.

The 24-core CPU and RTX 5080 16GB GPU handle rendering, modelling and AI learning tasks. Four memory slots allow expansion up to 192GB total capacity. Builders who need more than 64GB of memory out of the box should look at a different configuration. The mid-tower case fits standard ATX layouts with liquid cooling.

4TB Samsung 990 PRO PCIe 4.0x4 NVMe SSD

The primary storage is a 4TB Samsung 990 PRO NVMe drive connected via PCIe 4.0x4. Sequential reads reach up to 7450 MB/s and writes up to 6900 MB/s. The motherboard provides three M.2 connectors for additional drives. No mechanical hard drive is included in this configuration.

Questions about this item

What case clearance is needed for the 360 mm liquid cooler radiator?

The mid-tower chassis measures 447 mm deep, 215 mm wide and 469 mm high; the 360 mm radiator mounts at the front behind two 140 mm PWM fans, so allow at least that depth plus cable routing space.

How is the 360 mm AIO cooler installed, and what step do builders often miss?

The cooler ships pre-filled; mount the radiator to the front panel with the supplied brackets, connect the pump header to the CPU_FAN connector on the GIGABYTE Z890M AORUS board, then plug the two 140 mm fans into SYS_FAN headers — forgetting the pump header causes the CPU to overheat at 3.7 GHz.

When will the 4 TB Samsung 990 PRO SSD need replacement, and what capacity can the board take?

The drive is rated for PCIe 4.0 x4 speeds of 7450 MB/s read and 6900 MB/s write; the motherboard provides three M.2 slots supporting up to 192 GB of total system memory, so a future NVMe upgrade can use any free M.2 slot.
