Core Specification

This Adamant Custom desktop is a 2026 gaming workstation built around a 24-core Intel Core i9-14900K processor and an Nvidia GeForce RTX 5090 graphics card with 32 GB of video memory. It ships with 128 GB of DDR5 RAM, a 2 TB NVMe SSD and a 10 TB hard drive. A 360 mm liquid cooler and a 1200 W 80 PLUS Gold power supply support the high-performance components inside a Corsair 4000D tempered-glass case.

Who This Suits

The system targets professionals who need sustained multi-core performance for rendering, modelling or AI learning workloads alongside high-end gaming capability. The 32-thread CPU and large memory capacity handle parallel tasks that smaller workstations cannot. Buyers who only require mainstream gaming performance, quieter air-cooled operation or a more compact footprint should consider alternative configurations.

Deciding Specification

The single specification that determines suitability is the 24-core Intel Core i9-14900K processor paired with 128 GB of DDR5 memory. This combination defines the workstation's ability to run heavy multi-threaded applications and large datasets simultaneously. If your workflow does not demand that level of parallel compute and memory capacity, a lower-specification system will meet your needs more efficiently.

Questions about this item

Will the Z790 PRIME motherboard still fit my existing LGA 1700 CPU cooler if I decide to keep it?

The system ships with a 360mm AIO liquid cooler mounted on the Core i9-14900K, so the stock cooler occupies the socket; any LGA 1700 cooler you keep would need to be swapped in place of the included unit.

How can I verify the RTX 5090 32GB is running at full PCIe 4.0 x4 bandwidth after assembly?

Open GPU-Z or the NVIDIA control panel and confirm the bus interface reads PCIe 4.0 x4; the Samsung 990 PRO NVMe SSD also runs at PCIe 4.0 x4 with sequential reads up to 7450 MB/sec and writes up to 6900 MB/sec as a cross-check.

What cables and accessories come in the Corsair 4000D box versus what I must source myself?

The case includes its front-panel USB 3.2 Type-C, two USB 3.2 Gen 1 ports and an audio combo jack; the Thermaltake 1200W PSU supplies all modular power cables; Windows 11 Pro is pre-installed — you only add a monitor, keyboard and mouse.
