20-Core Ultra 7 Workstation

This Adamant Custom desktop pairs a 20-core Intel Core Ultra 7 265K processor with 192GB DDR5 memory and a 4TB Samsung 990 PRO NVMe drive. The GeForce RTX 5070 Ti adds 16GB video memory for rendering, modelling and AI workloads. Windows 11 Pro ships pre-installed on the Z890 TUF motherboard.

Liquid Cooling and 850W Bronze PSU

A 240mm quiet-edition liquid cooler handles the CPU while three 120mm front fans move air through the Antec P20 tempered-glass case. The Thermaltake Smart 850W 80 PLUS Bronze supply uses a 140mm fan and Japanese main capacitors for low-noise operation. Dust filters on bottom, front and top reduce internal buildup.

Upgrade From Smaller Memory or SATA Storage

Builders moving from 64GB kits or SATA SSDs gain headroom for large datasets and faster asset streaming. The four M.2 slots and four SATA ports allow further expansion without replacing the board. Buyers who need more than 192GB RAM or a second GPU should consider a different platform.

Questions about this item

How do I install the 240mm liquid cooler and what step is often missed?

Mount the radiator to the case top or front using the supplied brackets, then attach the pump block to the LGA 1851 socket with the pre-applied thermal paste; the step most people forget is connecting the pump header and the 120mm fan headers to the Z890 motherboard so the cooler actually runs.

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

The sealed AIO loop requires no refill; plan to clean dust from the radiator fins and the two 120mm fans every 6 to 12 months, and replace the whole unit only if pump noise appears or temperatures rise unexpectedly.

What limit shows up first under sustained load on this system?

The Thermaltake Smart 850W 80 PLUS Bronze PSU sets the power ceiling; continuous full CPU and RTX 5070 Ti draw can approach its rated output, so sustained heavy workloads will hit the power-supply limit before thermal throttling occurs.
