24-Core i9-14900K Workstation

This Adamant Custom tower pairs a 24-core Intel Core i9-14900K with 128GB DDR5 and an Nvidia GeForce RTX 5090 32GB GPU. The system targets professionals who need sustained compute for rendering, modelling and AI learning workloads alongside high-end gaming capability. Windows 11 Pro 64-bit is pre-installed on the 8TB NVMe array.

360mm Liquid Cooling and 1200W Gold PSU

A 360mm Quiet Edition AIO cooler handles the CPU thermal load while three 120mm front fans and a 140mm PSU fan move air through the Antec P20 mid-tower. The Thermaltake Toughpower 1200W 80 PLUS Gold unit supplies power with Japanese main capacitors and protections for over voltage, under voltage, over power and short circuit. Dust filters cover bottom, front and top intakes.

8TB Samsung 990 PRO NVMe Storage

Two 4TB Samsung 990 PRO PCIe 4.0x4 drives deliver sequential reads up to 7450 MB/sec and writes up to 6900 MB/sec, forming the 8TB boot and scratch volume. A 10TB HDD with 256MB cache provides secondary bulk storage. Buyers who need more than 8TB of high-speed NVMe capacity should look elsewhere.

Questions about this item

How do I install the 360 mm liquid CPU cooler in the Antec P20 case, and what step is often missed?

Mount the radiator to the top or front 120 mm fan positions, then connect the pump header to the CPU_FAN connector on the Z790 TUF motherboard; the step most people miss is setting the pump to full speed in the BIOS so it does not run in quiet mode by default.

What maintenance will the 360 mm liquid cooler and the 1200 W 80 PLUS Gold PSU need over time?

The sealed AIO loop requires no refill; plan to clean dust from the radiator fins and the PSU intake filter every 6 to 12 months, and replace the 120 mm case fans if bearing noise appears.

Which limit appears first when the i9-14900K and RTX 5090 run sustained heavy workloads?

The 1200 W PSU ceiling is reached before the 360 mm radiator can reject the combined heat, so the system will throttle or shut down once total draw approaches that rating.
