System Identity

This Adamant Custom desktop is a new mid-tower workstation built around a 24-core Intel Core i9-14900K processor and 32GB of DDR5 memory. It targets professionals and enthusiasts who need high single-thread and multi-thread throughput for compute-heavy workloads such as rendering, compilation or simulation. The system ships with Windows 11 Pro and a 4TB Samsung 990 PRO NVMe drive. Buyers who require a discrete graphics card for gaming or GPU acceleration should look elsewhere.

Deciding Specification

The CPU delivers 24 cores and 32 threads with a base clock of 3.2GHz and a maximum turbo frequency of 6.00GHz, supported by 36MB of L3 cache. This core count and frequency ceiling determine whether the machine can finish your typical workloads within acceptable time limits. The Z790 PRIME motherboard provides four memory slots, allowing expansion up to 192GB of DDR5 if your applications demand more capacity than the factory 32GB.

Thermals and Power

A 360mm quiet-edition liquid cooler handles the processor heat load while a 140mm fan in the Thermaltake Smart 850W 80 PLUS Bronze power supply maintains low noise levels under typical loads. The PSU includes over-voltage, under-voltage, over-power and short-circuit protection. The Corsair 4000D chassis measures 490 x 239 x 486 mm and offers two internal 3.5-inch and two 2.5-inch drive bays for future storage additions.

Questions about this item

How does the 24-core i9-14900K perform inside a mid-tower with a 360 mm liquid cooler?

The 360 mm Quiet Edition AIO keeps the 24-core processor within thermal limits so it can sustain high clocks across all cores during heavy workloads.

What does the PCIe 4.0 x4 link mean for the Samsung 990 PRO 4 TB drive in this Z790 board?

The drive connects through an M.2 slot wired for PCIe 4.0 x4, delivering up to 7450 MB/s reads and 6900 MB/s writes without bottleneck.

Will the Corsair 4000D case accept a full-length graphics card if I add one later?

The mid-tower chassis provides 490 mm depth and supports long GPUs, while the 850 W Bronze PSU supplies enough power for high-end cards.
