12-Core Ryzen Workstation

This Adamant Custom desktop pairs a 12-core AMD Ryzen 9 9900X3D processor with 64GB of DDR5 memory and an Nvidia GeForce RTX 5090 graphics card. A 2TB Samsung 990 PRO NVMe drive provides primary storage. The system ships with Windows 11 Pro installed and uses a 240mm liquid cooler for the CPU.

Suited to Modelling and AI Tasks

The 12-core CPU, 64GB RAM and RTX 5090 32GB GPU combination targets 3D modelling, video editing, rendering and AI learning workloads. Buyers who need more than 64GB of memory or additional internal drive bays beyond the two 3.5-inch and two 2.5-inch slots should consider a different platform.

64GB RAM and 2TB NVMe Headroom

Four memory slots support up to 192GB total, so the current 64GB leaves room for expansion. The 2TB NVMe drive delivers sequential reads up to 7450 MB/sec and writes up to 6900 MB/sec. The 1200W 80 PLUS Gold power supply provides overhead for the configured components.

Questions about this item

What motherboard socket must my CPU cooler match for the Ryzen 9 9900X3D?

The CPU uses the AM5 socket, so any cooler you keep must list AM5 mounting support.

Will my existing SATA SSDs or hard drives connect to the PRIME X870-P board?

Yes, the motherboard provides two SATA 6Gb/s ports for 2.5 or 3.5 drives.

How can I verify the Samsung 990 PRO is running at PCIe 4.0 x4 after setup?

In Windows Task Manager or CrystalDiskMark, the drive should show sequential reads near 7450 MB/s and writes near 6900 MB/s.
