System purpose

This Adamant Custom workstation pairs an 8-core Ryzen 7 9800X3D processor with an RTX 5090 graphics card and 192GB of DDR5 memory. It ships with Windows 11 Pro on a 2TB NVMe drive and uses liquid cooling for the CPU. The platform targets modelling, video editing, rendering and AI learning workloads alongside gaming.

Buyer fit

The build suits users who need large memory capacity and high single-thread frequency for creative and compute tasks. It is not for buyers who want more storage than the single 2TB drive provides or who need additional internal drive bays populated. The four memory slots are already full at the 192GB maximum, so further RAM expansion is not possible.

Build context

The PRIME X870-P motherboard supplies rear USB4 ports at 40Gbps, 2.5Gb Ethernet and Wi-Fi 7 connectivity. A 1200W 80 PLUS Gold PSU powers the components while the Corsair 4000D case leaves two 3.5-inch and two 2.5-inch bays free for extra drives. The 240mm liquid cooler handles CPU thermals, freeing internal airflow for the GPU.

Questions about this item

Does the 1200W 80 PLUS Gold PSU include the 12V-2x6 connector the RTX 5090 32GB needs?

The Thermaltake Toughpower 1200W 80 PLUS Gold unit supplies the 12V-2x6 cable required by the RTX 5090 32GB, so no extra adapter is necessary.

Will the PRIME X870-P motherboard still run my existing SATA SSDs alongside the 2TB Samsung 990 PRO?

Yes, the board provides four SATA 6Gb/s ports, so current SATA drives can be used together with the NVMe boot drive.

How can I confirm the 192GB DDR5 kit is operating at its rated speed after first boot?

Open Task Manager’s Performance tab or run CPU-Z; the Memory section should show 192GB DDR5 at the configured frequency.
