Liquid-cooled workstation desktop

This Adamant Custom gaming desktop pairs a 12-core AMD Ryzen 9 9900X3D processor with an Nvidia GeForce RTX 5090 graphics card. It runs Windows 11 Pro and includes a 240 mm liquid CPU cooler in a mid-tower case. The system is built for high-performance computing and gaming workloads.

Suits creators needing GPU memory and fast storage

The 32 GB GPU frame buffer and 4 TB NVMe SSD support large assets and rapid loading. Buyers who want more system memory than 32 GB DDR5 or who need additional M.2 slots populated should look at a different configuration. The four memory slots allow expansion up to 192 GB.

32 GB RTX 5090 frame buffer decides fit

The graphics card provides 32 GB of video memory, a capacity that determines whether the system handles your largest scenes and models. If your workflow demands more GPU memory, this card will not meet the requirement.

Questions about this item

How loud is the 240mm liquid cooler and the 140mm PSU fan when the Ryzen 9 9900X3D runs at 5.50 GHz all day?

The CPU uses a 240mm Quiet Edition AIO and the Thermaltake 1200W Gold PSU has an ultra-quiet 140mm fan designed for low noise under load.

Which display cables must I already own to connect a monitor to the RTX 5090?

The RTX 5090 uses a PCI Express x16 slot and standard DisplayPort or HDMI outputs; check your monitor for matching inputs.

Can I reuse my existing SATA SSDs or hard drives inside the Antec P20 case?

Yes, the case provides two internal 3.5"/2.5" bays and the motherboard has two SATA 6Gb/s ports for additional drives.
