Adamant Custom 20-Core Workstation Gaming PC

This desktop combines a 20-core Intel Core Ultra 7 265K processor with an Nvidia GeForce RTX 5080 graphics card. It targets creators and engineers who need strong multi-threaded compute for rendering, modelling and AI learning workloads alongside high-end gaming performance. The system ships with Windows 11 Pro installed and is fully customizable to order.

240mm Liquid Cooling and 1000W Gold PSU

A 240mm Quiet Edition AIO cooler handles the CPU while the Thermaltake Toughpower 1000W 80 PLUS Gold unit delivers stable power with Japanese main capacitors. Case airflow uses three 140mm fans rated at 1500rpm and 30dBA each at the front and rear. Over-voltage, under-voltage, over-power and short-circuit protections are built into the power supply.

Dual 4TB Samsung 990 PRO SSDs and Wi-Fi 7

Two 4TB Samsung 990 PRO PCIe 4.0x4 drives provide 8TB total capacity with sequential reads up to 7450 MB/s and writes up to 6900 MB/s. The Z890 TUF motherboard adds Thunderbolt 4, USB 20Gbps and 10Gbps ports plus Intel 2.5Gb Ethernet. Wireless connectivity uses Wi-Fi 7 2x2 and Bluetooth 5.4.

Questions about this item

How do I install the 240mm liquid CPU cooler, and which step is often missed?

Mount the radiator to the Ceres 300 case using the included brackets, connect the pump to the CPU_FAN header on the Z890 motherboard, and plug the 140mm fans into the fan headers. The step most people forget is removing the protective plastic film from the cold-plate before seating it on the Core Ultra 7 265K.

What maintenance or replacement will the 240mm AIO liquid cooler need later?

The sealed 240mm Quiet Edition loop is maintenance-free for its service life. If pump noise increases or CPU temperatures rise after several years, the entire AIO unit must be replaced; no coolant refill or individual part service is designed.

What limit appears first during sustained heavy workloads on the RTX 5080 16GB?

The GPU will hit its power and thermal ceiling first. The 1000W 80 PLUS Gold PSU delivers ample headroom, so the 16GB RTX 5080 throttles its boost clocks once the 240mm AIO and case airflow can no longer dissipate the heat fast enough.
