Core Ultra 7 265K Workstation

The Adamant Custom desktop pairs a 20-core Intel Core Ultra 7 265K processor with 192GB of DDR5 memory and a 4TB NVMe solid-state drive. Liquid cooling keeps the CPU stable under sustained multi-threaded workloads. Windows 11 Pro is pre-installed for immediate deployment.

240mm AIO and Z890 Connectivity

A 240mm quiet-edition liquid cooler mounts directly to the LGA 1851 socket inside an Antec P20 tempered-glass mid-tower. The TUF Gaming Z890 motherboard provides Thunderbolt 4, USB 20Gbps and 10Gbps Type-C ports, four M.2 slots and 2.5Gbps Ethernet alongside Wi-Fi 7 and Bluetooth 5.4. Front-panel I/O adds USB 3.2 Gen 2 Type-C and USB 3.0 for everyday peripherals.

Integrated Graphics Upgrade Path

The system ships with Intel integrated graphics driving HDMI and DisplayPort outputs, suitable for productivity and light content creation. Builders who need dedicated GPU acceleration for rendering, simulation or gaming can add a discrete card using the available PCIe slots and the 750W 80 PLUS Bronze power supply. The jump is worth it when workloads exceed integrated graphics capability.

Questions about this item

Does the Thunderbolt 4 port on the Z890 motherboard cap at 40 Gbps?

The rear Thunderbolt 4 Type-C port supports up to 40 Gbps bandwidth for data, display and charging.

Will the 240 mm AIO cooler fit inside the Antec P20 mid-tower case?

Yes, the 240 mm radiator mounts in the front or top of the 469 x 220 x 490 mm case with standard 120 mm fan spacing.

How is the liquid cooler installed and what step do builders often miss?

The AIO arrives pre-filled; mount the radiator, attach fans, connect the pump header to CPU_FAN and the fan cables to a PWM header — many forget the pump header.
