20-Core Liquid-Cooled Workstation

This Adamant Custom business desktop pairs a 20-core Intel Core Ultra 7 265K processor with 32 GB of DDR5 memory and an Nvidia RTX A400 graphics card. It is built for professionals who need reliable multi-threaded compute and certified drivers for creative or engineering applications. The system ships with Windows 11 Pro and includes 8 TB of NVMe SSD storage plus a 10 TB hard drive for large project libraries.

240 mm AIO and 750 W Bronze PSU

A 240 mm quiet-edition liquid cooler handles the CPU while a Thermaltake Smart 750 W 80 PLUS Bronze supply with a 140 mm fan delivers power. The case uses three 120 mm RGB fans for airflow and the PSU’s Japanese main capacitor and protection circuits keep voltages stable. Acoustic output stays low during typical workloads thanks to the liquid loop and the PSU’s ultra-quiet fan design.

Upgrade from 8–12 Core Air-Cooled Towers

Moving from an older 8 to 12 core air-cooled workstation brings 20 cores, DDR5 bandwidth and PCIe 4.0 NVMe speeds that cut render and compile times. The jump is worth it when current projects exceed memory capacity or when GPU-accelerated workflows need certified RTX drivers. Buyers who only need basic office productivity or who require more than 4 GB of VRAM should look elsewhere.

Questions about this item

How do I install the 240 mm liquid cooler on the LGA 1851 socket without damaging the CPU?

Align the cooler's mounting bracket with the four holes around the LGA 1851 socket, tighten the screws in a cross pattern until snug, then connect the pump header to the CPU_FAN connector on the Z890-PLUS TUF motherboard.

When will the 10 TB HDD with 256 MB cache need replacement under typical workloads?

The mechanical drive has no fixed lifespan; monitor SMART attributes for reallocated sectors or rising seek errors and replace the 10 TB unit when the health indicator drops below the manufacturer's threshold.

At what point does the RTX A400 4 GB frame buffer become the bottleneck during sustained rendering?

The 4 GB VRAM on the RTX A400 fills first when scenes exceed that capacity, forcing texture swaps over the PCI Express x16 link and reducing sustained throughput.
