20-Core AI Workstation

The Adamant Custom desktop pairs a 20-core Intel Core Ultra 7 265K processor with an Nvidia GeForce RTX 5080 graphics card. It ships with 64GB of DDR5 memory, a 4TB NVMe SSD and a 10TB hard drive. The system targets professionals who need rendering, modelling or AI learning performance alongside gaming capability.

240mm Liquid Cooler and 1000W PSU

A 240mm quiet-edition AIO cooler handles the CPU thermal load while a Thermaltake Toughpower 1000W 80 PLUS Gold unit supplies power with Japanese capacitors and a 140mm low-noise fan. The Z890 TUF motherboard adds Thunderbolt 4, USB 20Gbps and 10Gbps ports plus Wi-Fi 7 and Bluetooth 5.4 connectivity.

PCIe 4.0 Storage Ceiling

The 4TB Samsung 990 PRO operates at PCIe 4.0x4 with sequential reads up to 7450 MB/sec and writes up to 6900 MB/sec; faster PCIe 5.0 drives cannot exceed this interface limit. The 10TB hard drive adds bulk capacity at mechanical speeds. Four M.2 slots and four SATA 6Gb/s ports allow further expansion within the same bandwidth constraints.

Questions about this item

Will the 240 mm liquid cooler need its coolant topped up or the pump replaced during the life of the system?

The 240 mm AIO is a sealed unit; no coolant top-ups are required and the pump is rated for continuous operation.

What thermal limit will the Intel Core Ultra 7 265K hit first when all 20 cores run at 5.50 GHz for extended periods?

The CPU will reach its 5.50 GHz turbo ceiling and then throttle to stay within its thermal envelope under sustained all-core load.

How loud does the 240 mm AIO and the PSU fan get when the RTX 5080 and CPU are both at full load all day?

The 240 mm Quiet Edition AIO and the 140 mm PSU fan are both specified for ultra-quiet operation, keeping system noise low during continuous heavy workloads.
