14-Core Liquid-Cooled Workstation

This Adamant Custom desktop pairs a 14-core Intel Core Ultra 5 245K processor with a 240mm AIO liquid cooler and an Nvidia GeForce RTX 5090 graphics card. It ships with 128GB of DDR5 memory and 8TB of NVMe storage across two Samsung 990 PRO drives. Windows 11 Pro is pre-installed on the Z890 TUF motherboard platform.

Suited for AI Development and Heavy Multitasking

The 128GB DDR5 capacity and 32GB GPU frame buffer support large-language-model inference, video editing timelines and multi-VM workloads. Thunderbolt 4 and Wi-Fi 7 provide high-speed peripheral and network connectivity. Buyers who need ECC memory, dual-GPU compute scaling or more than 192GB total system memory should consider alternative platforms.

8TB NVMe and 192GB Memory Ceiling

Two 4TB PCIe 4.0 SSDs deliver up to 7450 MB/s read and 6900 MB/s write speeds for project assets and scratch disks. The four DDR5 slots allow expansion to 192GB when workloads outgrow the factory 128GB. The 1000W 80 PLUS Gold PSU powers the RTX 5090 and CPU combination without headroom for additional high-power add-in cards.

Questions about this item

Do I need to buy a monitor separately to use this PC?

Yes, the system ships without a screen so you must provide your own display.

Can I keep my existing SATA SSDs or hard drives when I move to this machine?

The motherboard includes four SATA 6Gb/s ports and the case has one 3.5-inch or two 2.5-inch bays for additional drives.

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

Check that the 240mm AIO pump and fans spin quietly and monitor CPU temperatures in Windows to confirm they stay low under load.
