Ready-to-run 20-core workstation

This Adamant Custom desktop ships with Windows 11 Pro installed and a liquid-cooled Intel Core Ultra 7 265K at its heart. The 20-core processor reaches 5.50 GHz boost clocks and includes 30 MB of L3 cache. A 240 mm quiet-edition AIO keeps thermals in check while the system stays near-silent under load.

192 GB DDR5 and 4 TB NVMe

Four memory slots are fully populated with 192 GB of high-performance DDR5, matching the platform maximum. Storage is a single Samsung 990 PRO 4 TB drive delivering up to 7450 MB/s reads and 6900 MB/s writes over a PCIe 4.0 x4 link. No mechanical drives or optical bays are fitted.

Creators who need maximum local memory

The 192 GB ceiling suits large-language-model workloads, heavy timeline editing and massive scene rendering without paging. Buyers who want more storage than a single 4 TB volume should look elsewhere. The 1000 W Gold-rated supply and mid-tower chassis limit future multi-GPU expansion.

Questions about this item

What does the 20-core 3.7 GHz CPU deliver in everyday workstation tasks?

The 20-core Intel Core Ultra 7 265K runs at 3.7 GHz base with a 5.50 GHz boost and 30 MB L3 cache, giving strong multi-threaded throughput for rendering, modelling and AI workloads.

How fast can the 4 TB Samsung 990 PRO actually move data over its PCIe 4.0 x4 link?

The drive is rated for up to 7450 MB/s sequential read and 6900 MB/s sequential write, so large project files and game assets load at near-peak Gen 4 speeds.

Will the 240 mm liquid cooler and RTX 5090 both fit in the Antec P20 case?

Yes — the case measures 469 x 220 x 490 mm, supports E-ATX boards and has room for a 240 mm radiator plus a full-length graphics card.
