Adamant Custom
Liquid-cooled gaming desktop with a 14-core Intel Core Ultra 5 245K, 192GB DDR5, 1TB NVMe SSD and RTX 5060 graphics
The Adamant Custom desktop is a liquid-cooled workstation built around a 14-core Intel Core Ultra 5 245K processor and 192GB of DDR5 memory. It targets professionals who need high multi-threaded throughput for rendering, simulation or large dataset work. The RTX 5060 8GB GPU adds hardware-accelerated compute for AI-assisted pipelines. Buyers who need more than 192GB of RAM or a second graphics card should look elsewhere.
A 240mm quiet-edition AIO cooler handles the CPU while a 140mm fan on the 750W 80 PLUS Bronze power supply keeps internal airflow low-noise. The Corsair 4000D chassis provides tempered-glass panels and structured cable routing to support steady thermals under sustained loads. Over-voltage, under-voltage, over-power and short-circuit protections are built into the PSU. The system ships with Windows 11 Pro 64-bit pre-installed and no bloatware.
The motherboard uses the Z890 chipset with an LGA 1851 socket and four DDR5 slots, all populated to reach the 192GB maximum. Storage is a single 1TB Samsung 990 PRO PCIe 4.0x4 NVMe drive rated for 7450 MB/s reads and 6900 MB/s writes. Rear I/O includes Thunderbolt 4, USB 20Gbps and 10Gbps Type-C ports, 2.5Gb Ethernet and Wi-Fi 7 2x2 with Bluetooth 5.4.

The cooler ships pre-filled; secure the pump block to the LGA 1851 mounting bracket with the supplied standoffs, then connect the pump header and 140 mm fan header to the Z890-PLUS TUF motherboard. The step often missed is removing the protective film from the cold-plate before seating it on the CPU.
The 240 mm AIO pump and 140 mm radiator fan are the only moving parts; expect the pump to require service after several years of continuous operation. The 750 W 80 PLUS Bronze PSU uses Japanese main capacitors rated for long life, while the 192 GB DDR5, 1 TB Samsung 990 PRO SSD and RTX 5060 8 GB GPU have no user-serviceable wear items.
The 240 mm Quiet Edition AIO is sized for the CPU base power; sustained all-core turbo at 5.20 GHz will hit the cooler's heat-dissipation ceiling before the 750 W PSU or motherboard VRM reach their rated limits, causing the firmware to throttle clock speeds to maintain safe temperatures.
