Adamant Custom i9-14900K Workstation

This desktop combines a 24-core Intel Core i9-14900K processor with an Nvidia GeForce RTX 5090 graphics card. It ships with 128GB of DDR5 memory and a 1TB Samsung 990 PRO NVMe drive. The system targets professionals who need high parallel throughput for editing, rendering, modelling and AI learning workloads. Windows 11 Pro is pre-installed on the Z790 motherboard platform.

360mm Liquid Cooling and 1200W Gold PSU

A 360mm quiet-edition AIO cooler handles the CPU while a Thermaltake Toughpower 1200W 80 PLUS Gold unit supplies power. The PSU uses Japanese main capacitors and a 140mm fan designed for low noise. Protection circuits cover over-voltage, under-voltage, over-power and short-circuit events. The Corsair 4000D chassis provides structured airflow for the liquid loop.

Sustained Load on 24 Cores and 32GB GPU VRAM

The i9-14900K maintains up to 6.00 GHz across 24 cores and 32 threads with 36MB of L3 cache during extended compute tasks. The RTX 5090 contributes 32GB of video memory for large scene rendering and model training. The 990 PRO SSD delivers sequential reads up to 7450 MB/s and writes up to 6900 MB/s to keep data flowing. Intel 2.5Gb Ethernet, Wi-Fi 6 and Bluetooth 5.2 maintain connectivity throughout long sessions.

Questions about this item

How is the 360 mm liquid cooler mounted to the LGA 1700 socket, and which step do builders often skip?

The AIO bracket attaches to the motherboard back-plate with four spring-loaded screws; the step most people miss is removing the protective film from the cold-plate before tightening.

What components will need replacement first during the system's lifespan?

The 140 mm radiator fan and the pump in the 360 mm AIO are the only moving parts; expect to swap the fan after several years of continuous operation.

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

The 1200 W 80 PLUS Gold PSU caps total system draw, so power delivery hits its ceiling before the CPU reaches its 6.00 GHz boost or the GPU saturates its 32 GB VRAM.
