24-Core i9-14900K Workstation

This Adamant Custom tower pairs a 24-core Intel Core i9-14900K processor with an Nvidia GeForce RTX 5090 graphics card holding 32GB of video memory. The system ships with 64GB of DDR5 memory and a 1TB Samsung 990 PRO NVMe drive running over PCIe 4.0 x4. Windows 11 Pro is pre-installed for creators and engineers who need immediate AI-ready compute.

Sustained Load Behaviour

A 360mm Quiet Edition liquid cooler handles the CPU while the Cooler Master HAF 500 case moves air through two 200mm front fans and a rear 120mm fan. The Thermaltake Toughpower 1200W 80 PLUS Gold supply uses a 140mm fan and Japanese capacitors to deliver stable power during long rendering or modelling sessions. Thermal throttling is minimised by the high-airflow chassis and liquid loop.

Installation and Common Issues

The fully assembled tower requires only peripheral connections and power. Builders adding storage must use the four M.2 slots or two 2.5-inch and two 3.5-inch bays; no 3.5-inch brackets are included beyond the two standard positions. Front-panel USB 3.2 Gen 2 Type-C and Gen 1 ports need matching motherboard headers already wired. Wi-Fi 6 and Bluetooth 5.2 antennas attach to the rear I/O panel.

Questions about this item

How much heat and noise should I expect from the 1200 W PSU and 360 mm liquid cooler when the i9-14900K and RTX 5090 run all day?

The Thermaltake 1200 W 80 PLUS Gold unit uses a 140 mm ultra-quiet fan and Japanese capacitors, while the 360 mm Quiet Edition AIO is designed for low noise under sustained 24-core loads.

Which peripherals and cables must I already own to start using this tower PC?

The system ships with Windows 11 Pro installed and includes Wi-Fi 6 and BLUETOOTH 5.2, so only a display, keyboard and mouse are required to begin working.

Will my existing 2.5 Gb Ethernet switch and SATA SSDs work with the Z790 AORUS motherboard?

Yes — the board provides an Intel 2.5 Gb LAN port and six SATA 6 Gb/s connectors supporting RAID 0, 1, 5 and 10 for legacy drives.
