24-Core Liquid-Cooled Workstation

The Adamant Custom desktop pairs a 24-core Intel Core Ultra 9 285K processor with 32GB of DDR5 memory and an Nvidia GeForce RTX 5090 graphics card. A 360mm liquid cooler manages CPU thermals while the system ships with Windows 11 Pro installed. It targets creators and gamers who need high multi-threaded throughput and 32GB of video memory in a single tower.

Tower Build With Front USB 3.2 Gen 2x2

The white tempered-glass chassis measures 447 x 215 x 469 mm and holds two 3.5-inch and two 2.5-inch internal bays. Front I/O includes one USB 3.2 Gen 2x2 Type-C port, two USB 3.0 ports and dual audio jacks. A Thermaltake Toughpower 1200W 80 PLUS Gold unit with Japanese capacitors and a 140mm fan delivers protected, low-noise power. Rear connectivity adds USB4 Type-C, multiple USB 3.2 and 2.0 ports, Intel 2.5Gb Ethernet, Wi-Fi 7 and Bluetooth 5.4.

Storage Layout And Expansion Headroom

Dual 4TB Samsung 990 PRO NVMe drives occupy two M.2 slots, leaving one M.2 connector and four SATA 6Gb/s ports with RAID 0, 1, 5, 10 support for further upgrades. The 10TB hard drive uses a 3.5-inch bay, so the second bay remains open for additional bulk storage. Four DDR5 slots are populated to 32GB with a 192GB ceiling, and the Z890 motherboard provides mid-board headers for extra front-panel USB Type-C and Type-A connections.

Questions about this item

What PCIe generation does the Z890 chipset use for the Samsung 990 PRO SSDs, and what sequential speeds does that cap in practice?

The Z890 board wires the two M.2 slots to PCIe 4.0 x4, so each Samsung 990 PRO reaches up to 7450 MB/s read and 6900 MB/s write in real workloads.

What clearance does the 360 mm radiator need, and which fan mounts does it occupy in this case?

The 360 mm AIO fits the top of the chassis, using the three 140 mm fan positions; the case measures 447 mm deep, 215 mm wide and 469 mm high, leaving room for the radiator and fans.

How is the RTX 5090 powered from the Thermaltake 1200 W unit, and which cable mistake do builders make?

The PSU includes native 12VHPWR cables — plug the single 16-pin connector straight into the card; the common error is using two 8-pin adapters instead of the dedicated lead.
