24-Core Liquid-Cooled Gaming Desktop

The Adamant Custom tower pairs a 24-core Intel Core Ultra 9 285K processor with a GeForce RTX 5090 graphics card. A 360 mm liquid cooler keeps the CPU stable under load while 32 GB of DDR5 memory and a 1 TB NVMe SSD provide fast throughput for modern titles and creative workloads. Windows 11 Pro comes pre-installed.

Built for 4K gaming and heavy content creation

This system suits players targeting high refresh rates at 4K resolution and professionals who need GPU acceleration for rendering or AI tasks. The four memory slots allow expansion up to 192 GB for larger datasets. Buyers who only need 1080p performance or who prefer air cooling will find simpler configurations more appropriate.

32 GB DDR5 and 1 TB NVMe headroom

The 32 GB kit handles current games and multitasking comfortably, while the Samsung 990 PRO SSD delivers read speeds up to 7450 MB/s and writes up to 6900 MB/s for quick level loads and project opens. Memory can be doubled or quadrupled using the spare slots, but storage expansion beyond the single M.2 drive requires adding SATA drives or external solutions.

Questions about this item

Does the PC include a monitor, keyboard or mouse so it works straight away?

No screen, keyboard or mouse is listed; the system ships as a tower only and you will need to connect your own display and peripherals.

Can I keep my existing SATA hard drives and plug them into this motherboard?

The Gigabyte Z890 UD board provides four SATA 6 Gb/s ports with RAID 0, 1, 5, 10 support so current SATA drives will connect directly.

How can I confirm the liquid cooler is running correctly after I power on?

Enter the BIOS or monitoring software and verify the CPU fan header reports pump speed and that coolant temperature stays stable under load.
