Adamant Custom
A 16-core liquid-cooled desktop with 128GB DDR5 and 1TB NVMe storage for intensive workloads
The Adamant Custom tower pairs a 16-core AMD Ryzen 9 9950X3D processor with 128GB DDR5 memory and a 1TB NVMe solid-state drive. Integrated Radeon graphics handle display output through HDMI and two USB4 ports. The system targets professionals who need high thread counts and large memory capacity for rendering, compilation or virtualisation workloads.
A quiet-edition all-in-one cooler uses a 360mm radiator and a 140mm fan to keep the CPU at low temperatures during sustained loads. The Thermaltake Smart 850W 80 PLUS Bronze power supply includes Japanese main capacitors and protection against over-voltage, under-voltage, over-power and short-circuit events. Acoustic output remains low in typical workstation scenarios.
Memory ships as 128GB DDR5 high-performance modules occupying all four DIMM slots on the PRIME X870-P motherboard. Maximum supported capacity is 192GB, so no further expansion is possible without removing existing sticks. Buyers who need more than 128GB must plan a full memory replacement rather than a simple upgrade.

The cooler comes pre-filled and pre-mounted to the CPU; the step people miss is screwing the radiator fans to the top panel before connecting the pump header to the motherboard CPU_FAN connector.
Dust the 140 mm PSU fan intake every few months; the unit has no user-serviceable parts, so if the fan fails the entire PSU is replaced.
The 128 MB L3 cache and 5.70 GHz boost clock are held until the coolant saturates; then the CPU throttles to stay within its thermal envelope.
