Custom Gaming Workstation

The Adamant Custom gaming desktop pairs an 8‑core Ryzen 7 9800X3D with a GeForce RTX 5090 32GB GPU, 128GB DDR5 memory and a 4TB NVMe SSD plus 10TB HDD in a mid‑tower case. Liquid cooling and a 1200W 80 PLUS Gold PSU support sustained workloads. Windows 11 Pro is pre‑installed.

Suited for AI and rendering; not for compact builds

Creators running local AI learning, 3D modelling or video editing benefit from the 96MB L3 cache, 128GB DDR5 capacity and 4TB Samsung 990 PRO read speeds up to 7450 MB/sec. The 469×220×490 mm chassis and 240mm AIO require standard mid‑tower space, so builders needing a small‑form‑factor system should look elsewhere.

Deciding spec: RTX 5090 32GB VRAM

The single specification that determines fit is the graphics card’s 32GB video memory. Workloads such as large‑model inference, high‑resolution texture baking or multi‑monitor 8K output need that capacity; lighter gaming or general office tasks do not.

Questions about this item

Will the AM5 socket on the PRIME X870-P motherboard accept my existing AM5 cooler?

The CPU ships with a 240mm AIO Quiet Edition liquid cooler mounted on the AM5 socket, so the stock cooler is already installed.

How can I verify the Samsung 990 PRO SSD is delivering its rated 7450 MB/s read and 6900 MB/s write speeds?

Run a PCIe 4.0 NVMe benchmark such as CrystalDiskMark on the 4TB M.2 drive; results should approach the sequential read and write figures.

Does the Antec P20 case include the 3 x 120mm front fans and dust filters, or must I buy them separately?

The case arrives with three 120mm front fans and bottom, front and top dust filters already fitted; no extra purchase is needed.
