Workstation-class gaming desktop

This Adamant Custom tower pairs a 24-core Intel Core Ultra 9 285K with an Nvidia GeForce RTX 5080 16GB GPU. The system ships with 128GB of DDR5 memory and a dual-drive layout of 8TB NVMe SSD plus 10TB HDD. It targets creators and AI workloads that need both high thread counts and large local datasets.

PCIe 4.0 storage ceiling

The two Samsung 990 PRO M.2 drives operate over PCIe 4.0 x4, capping sequential reads at 7450 MB/s and writes at 6900 MB/s. Four total M.2 connectors exist on the Z890 board, but only the CPU-attached lanes deliver that bandwidth. Additional NVMe devices would share chipset lanes and run slower.

Liquid-cooled tower with front I/O

A 360 mm quiet-edition AIO handles the CPU while four 140 mm case fans move air at 1500 rpm and 30 dBA each. The Ceres 300 chassis offers one front USB 3.2 Gen 2 Type-C, two USB 3.0 Type-A and HD audio. Rear I/O adds Thunderbolt 4, USB 20 Gbps and 10 Gbps ports plus 2.5 Gb Ethernet, Wi-Fi 7 and Bluetooth 5.4.

Questions about this item

Should I pick the 8 TB NVMe plus 10 TB HDD combo or look for a larger single NVMe drive?

The system ships with two 4 TB Samsung 990 PRO M.2 SSDs in RAID 0 for the 8 TB NVMe volume and a separate 10 TB 3.5-inch hard drive; the Z890 board has four M.2 slots total, so you can add more NVMe later if you need a single larger boot drive.

What does the 5.70 GHz turbo on the 24-core Ultra 9 285K actually deliver in a liquid-cooled tower?

With the 360 mm AIO the 285K can sustain its 5.70 GHz maximum turbo on lightly threaded workloads; all-core speeds will sit lower depending on the thermal headroom of the 1000 W Gold PSU and case airflow.

Does the Thunderbolt 4 Type-C port on the rear I/O cap at 40 Gbps or share bandwidth with the USB 20 Gbps ports?

The rear Thunderbolt 4 Type-C runs at full 40 Gbps independently; the adjacent USB 20 Gbps Type-C and three USB 10 Gbps ports each operate on their own controllers, so none of them reduce Thunderbolt throughput.
