Built for creators and power users

The Adamant Custom desktop pairs a 12-core AMD Ryzen 9 9900X3D processor with an Nvidia GeForce RTX 5070 graphics card. Sixty-four gigabytes of DDR5 memory and a liquid-cooled thermal design keep the system responsive during heavy multitasking. Windows 11 Pro is pre-installed and ready for professional workloads.

Storage capacity and headroom

A 1 TB Samsung 990 PRO NVMe drive delivers read speeds up to 7450 MB/s and write speeds up to 6900 MB/s for the operating system and active projects. A 10 TB hard drive with 256 MB cache adds deep bulk storage for media libraries and archives. Four memory slots support up to 192 GB total if future expansion is required.

Thermals, noise and power

A 240 mm quiet-edition liquid cooler handles the CPU while a 140 mm fan in the power supply runs at low noise. The Thermaltake Smart 850 W 80 PLUS Bronze unit provides stable power with protection against over-voltage, under-voltage, over-power and short-circuit events. Front-panel 140 mm PWM fans move air through the tempered-glass chassis.

Questions about this item

Will the X870 motherboard and AM5 socket let me reuse my existing DDR5 memory kits?

The board has four DDR5 slots with 64 GB installed and supports up to 192 GB, so compatible DDR5 modules can be added.

How can I confirm the 240 mm liquid cooler is keeping the 12-core CPU at safe temperatures?

Monitor core temps in BIOS or Windows; the 128 MB L3 cache and 5.50 GHz boost should stay well below thermal limits under load.

Which drives and cables are included, and what must I add for extra storage?

A 1 TB Samsung 990 PRO NVMe SSD and a 10 TB 3.5-inch HDD with 256 MB cache ship installed; two 2.5-inch and two 3.5-inch bays plus four M.2 slots remain free for expansion.
