Workstation build for AI and rendering

The Adamant Custom Business Desktop ships with a 24-core Intel Core i9-14900K and 128GB of DDR5 memory. A 360mm liquid cooler handles the thermal load of the 3.2GHz processor. The Nvidia RTX A400 provides four Mini DisplayPort outputs for multi-monitor professional workflows. This tower targets users who need high core counts and large memory capacity.

Check motherboard memory limits

The Z790 AORUS board supports up to 192GB across four slots, so the installed 128GB kit leaves room for expansion. Verify that your monitors accept Mini DisplayPort signals or budget for active adapters. The 850W power supply carries an 80 PLUS Bronze rating and includes protection circuits. Front-panel I/O includes USB 3.2 Gen 2 Type-C and USB 3.0 ports.

Storage mix and connectivity extras

A 1TB Samsung 990 PRO NVMe drive delivers read speeds up to 7450 MB/sec for the operating system and active projects. The 10TB hard drive adds bulk capacity with a 256MB cache. Integrated Wi-Fi 6 and 2.5Gb Ethernet provide flexible network options. Realtek 7.1 surround audio and a tempered-glass mid-tower case complete the package.

Questions about this item

Does the system ship with a keyboard, mouse or monitor, or are those bought separately?

The desktop includes the tower with liquid-cooled CPU, motherboard, memory, SSD, HDD, GPU and PSU. Keyboard, mouse and monitor are not included and must be purchased separately.

Should I choose the 128 GB DDR5 configuration or upgrade toward the 192 GB maximum?

128 GB DDR5 is installed across four slots. The board supports up to 192 GB, so 128 GB suits most workloads; only upgrade if your applications regularly exceed that capacity.

What does the 6.00 GHz turbo figure mean for daily workloads?

The i9-14900K can boost to 6.00 GHz on active cores, giving short bursts of maximum single-thread speed for compile, simulation or render tasks while the 360 mm liquid cooler sustains performance.
