Custom Workstation Build

This Adamant Custom desktop combines a 12-core Ryzen 9 9900X3D processor with an RTX 5090 graphics card, 128GB of DDR5 memory, a 4TB NVMe SSD and a 10TB hard drive in a mid-tower chassis. Liquid cooling and a 1200W 80 PLUS Gold power supply support sustained workloads. Windows 11 Pro is installed.

Suited For Multi-Tasking Creators

The 128GB memory capacity and 4TB NVMe drive suit professionals running virtual machines, large dataset analysis or complex rendering pipelines. The 10TB secondary drive adds local archive space. Buyers who need more than 192GB of memory or additional GPU compute density should look at a different platform.

Sustained Load Behaviour

A 240mm liquid cooler manages CPU thermals while the case provides three 120mm front fans and dust filters on every intake. The 1200W Gold-rated unit delivers stable power through extended render or training sessions. Rear USB4 ports at 40Gbps maintain high-speed peripheral throughput without throttling.

Questions about this item

What display connectors must my monitor provide for the RTX 5090?

The RTX 5090 uses a PCI Express x16 graphics interface, so your monitor needs a DisplayPort or HDMI input that matches the card's output ports.

Will the 4 TB Samsung 990 PRO NVMe share bandwidth with the 10 TB HDD on the PRIME X870-P motherboard?

No, the 4 TB NVMe connects via a dedicated PCIe 4.0 x4 M.2 slot while the 10 TB HDD uses a separate SATA 6 Gb/s port, so they operate independently.

How can I confirm the liquid cooler is running after I power on the system?

Watch for the 240 mm AIO pump and fan RPM in BIOS or monitoring software, and verify CPU temperatures stay near idle under Windows 11 Pro.
