Built for AI and rendering

This Adamant Custom tower pairs a 24-core Intel Core i9-14900K with an Nvidia GeForce RTX 5090 32GB GPU, 64GB DDR5 memory and 8TB NVMe SSD storage. Liquid cooling and a 1200W 80 PLUS Gold power supply support sustained workloads. Windows 11 Pro 64-bit is pre-installed for immediate deployment.

Replaces slower workstations

The jump is worth it when 24 cores at up to 6.00 GHz, 32GB GPU memory and dual 4TB Samsung 990 PRO drives cut render, training and compile times versus systems limited to fewer threads, less VRAM or SATA SSDs. The 360mm liquid cooler keeps clocks stable during long sessions.

Suits creators and researchers

Engineers running local LLMs, 3D artists baking complex scenes and developers compiling large codebases benefit from the core count, VRAM and fast storage. Buyers who need more than 64GB RAM or multiple GPUs should look at configurations with higher memory ceilings and additional PCIe slots.

Questions about this item

What case clearance does the 360 mm liquid cooler need for the Intel Core i9-14900K?

The Antec P20 mid-tower measures 469 mm deep, 220 mm wide and 490 mm high, with front-mounted 120 mm fans and dust filters on the bottom, front and top.

How is the 360 mm AIO cooler installed on the LGA 1700 socket, and what step is often missed?

Mount the radiator to the case front, attach the pump block to the LGA 1700 CPU using the supplied bracket, then connect the pump header and fan cables to the Z790 TUF motherboard — forgetting the pump power cable is the common error.

Which components may need replacement first in this tower workstation?

The 1200 W 80 PLUS Gold PSU, the 140 mm PSU fan, the three 120 mm front case fans and the AIO pump are the moving parts most likely to wear; the two Samsung 990 PRO 4 TB SSDs and the 10 TB HDD should be monitored for SMART warnings.
