Built for 12-core compute and 4K play

This Adamant Custom desktop pairs a 12-core Ryzen 9 9900X3D running at 4.4 GHz with an RTX 5070 12 GB GPU. The combination targets creators who render, compile or simulate while also gaming at high refresh rates. Windows 11 Pro ships pre-installed on the 2 TB NVMe boot drive.

Steps up from 8-core or air-cooled rigs

Moving from an 8-core processor to this 12-core, 24-thread CPU adds headroom for parallel workloads such as video timelines or virtual machines. The 240 mm liquid cooler keeps sustained clocks stable where tower coolers would throttle. The jump pays off when timeline scrubbing or multi-instance compiles become daily bottlenecks.

128 GB DDR5 and 12 TB total storage

Four populated slots deliver 128 GB of DDR5 with room to reach 192 GB if workloads grow. The Samsung 990 PRO NVMe drive reads at 7450 MB/s for project files, while the 10 TB HDD stores archives and raw footage. Builds needing more than 12 TB or faster-than-PCIe 4.0 scratch space will need external arrays.

Questions about this item

Will the 447 mm deep case fit on my desk?

The chassis measures 447 mm deep, 215 mm wide and 469 mm high, so check your available space against those dimensions.

How do I connect the 240 mm liquid cooler to the AM5 motherboard?

Mount the radiator to the case fan brackets, attach the pump block to the AM5 socket using the supplied bracket, then plug the pump header into the CPU_FAN connector and the fans into SYS_FAN headers.

Can I add more DDR5 memory later?

The board has four DDR5 slots with 128 GB installed; maximum supported capacity is 192 GB, so one 64 GB kit can be added if two slots remain free.
