Built for heavy workloads

This Adamant Custom desktop pairs a twelve-core AMD Ryzen 9 9900X3D with 192 GB of DDR5 memory and an Nvidia GeForce RTX 5070 graphics card. It ships with Windows 11 Pro and targets professionals who need serious compute and graphics headroom in a mid-tower chassis.

Storage capacity and limits

A 4 TB Samsung 990 PRO NVMe drive delivers sequential reads up to 7450 MB/s and writes up to 6900 MB/s for active projects, while a 10 TB hard drive with 256 MB cache provides deep bulk storage. The four memory slots are fully populated at the platform maximum of 192 GB, so further RAM expansion is not possible without replacing modules.

Thermals noise and power

A 240 mm liquid cooler handles the CPU and the 850 W 80 PLUS Bronze supply feeds the system, its 140 mm fan running quietly under typical loads. The Antec P20 case includes three 120 mm front fans plus dust filters on bottom, front and top panels to maintain airflow.

Questions about this item

Will the AM5 socket on the PRIME X870-P motherboard accept my existing AM4 cooler?

The AM5 socket has a different mounting pattern than AM4, so an AM4 cooler will not fit without a specific AM5 upgrade kit from the cooler manufacturer.

How can I verify the 240 mm liquid cooler is running after I build the system?

Check the pump RPM in BIOS or monitoring software and feel for warm tubing near the radiator; the 140 mm radiator fan should also spin at low speed under idle load.

Does the Antec P20 case include the 3.5-inch drive trays needed for the 10 TB HDD, or must I buy them separately?

The case provides two internal 3.5-inch bays with trays included, so the 10 TB drive can be installed without extra parts.
