Adamant Custom Ryzen 9 9900X3D Workstation

This Adamant Custom gaming desktop PC is built around a 12-core AMD Ryzen 9 9900X3D processor clocked at 4.4 GHz with up to 5.50 GHz boost. It targets professionals who need modelling, editing, rendering and AI learning performance in a single mid-tower system.

Suits heavy multitasking not light office work

The 192 GB DDR5 memory and RTX 5090 32 GB GPU serve creators running large datasets and complex simulations. Buyers who only need web browsing or standard office applications will find the specification excessive for those tasks.

192 GB DDR5 maximum memory capacity

Four slots are populated to the 192 GB limit supported by the motherboard. No further memory upgrades are possible without replacing modules, so confirm the capacity meets your workload before purchase.

Questions about this item

How can I confirm the 12-core Ryzen 9 9900X3D is running at its 5.50 GHz boost after setup?

Open Task Manager or a hardware monitor and watch the CPU frequency climb to 5.50 GHz under load; the 240 mm liquid cooler keeps thermals in check so the 128 MB L3 cache stays fully utilised.

What components arrive inside the CoolerMaster HAF 500 case and what must I source myself?

The box contains the complete build: Ryzen 9 9900X3D, 192 GB DDR5, 4 TB Samsung 990 PRO NVMe, 10 TB HDD, RTX 5090 32 GB, 1200 W Gold PSU, Wi-Fi 7 and Windows 11 Pro — only a monitor, keyboard and mouse are left to you.

Should I choose the 192 GB DDR5 configuration or a lower capacity for modelling and AI workloads?

The motherboard maxes at 192 GB across four slots and this unit already populates the limit, giving modelling, editing and AI learning the full memory bandwidth without future upgrades.
