20-Core Workstation with Liquid Cooling

This Adamant Custom desktop is built around a 20-core Intel Core Ultra 7 265K processor running at 3.9 GHz with a 5.50 GHz maximum turbo. It includes 64 GB of DDR5 memory and a 4 TB Samsung 990 PRO NVMe SSD. A 240 mm liquid cooler and a 750 W 80 PLUS Bronze power supply support sustained workloads in a tempered-glass mid-tower case. Windows 11 Pro is pre-installed.

Who This Suits and Who Should Look Elsewhere

Professionals needing high multi-thread CPU performance, large memory capacity and fast storage for compilation, rendering or data analysis will benefit from this configuration. Buyers who require a dedicated graphics card for 3D acceleration, GPU compute or multi-monitor gaming should consider a different system. The integrated graphics provide only basic display output via HDMI and DisplayPort.

Z890 Platform with Thunderbolt 4 and Wi-Fi 7

The TUF Gaming Z890-PLUS motherboard provides a Thunderbolt 4 Type-C port, multiple USB 20 Gbps and 10 Gbps connections, and four M.2 slots. Networking includes 2.5 Gbps Ethernet, Wi-Fi 7 and Bluetooth 5.4. Memory can be expanded to 192 GB across four slots. This platform determines the upgrade path for storage, memory and peripherals.

Questions about this item

How is the 240mm liquid cooler mounted to the LGA 1851 socket, and what step do builders often miss?

The 240mm AIO attaches to the LGA 1851 bracket using the supplied back-plate and four spring-loaded screws; the step most often missed is removing the protective plastic film from the cold-plate before tightening.

Which component will need attention first as the system ages, and what are the limits?

The 140mm PSU fan and three 120mm front case fans are the only moving parts; the 750W Thermaltake unit uses Japanese capacitors rated for long life, while the AIO pump is sealed and maintenance-free.

What thermal or power ceiling appears first during extended all-core workloads?

The 240mm Quiet Edition radiator and 750W Bronze PSU set the practical ceiling; sustained 20-core boosts up to 5.50 GHz will hit coolant temperature limits before the CPU throttles.
