Custom 20-core workstation gaming desktop

This system combines a 20-core Intel Core Ultra 7 265K processor with an Nvidia GeForce RTX 5090 32GB graphics card. It ships with 64GB DDR5 memory and a 1TB Samsung 990 PRO NVMe drive. Windows 11 Pro is pre-installed on a liquid-cooled platform built for rendering, modelling and AI workloads.

Upgrade from lower-core or air-cooled builds

The 20-core CPU reaches up to 5.50 GHz with 30 MB L3 cache while a 240mm quiet-edition liquid cooler manages thermals. A 1000W 80 PLUS Gold power supply delivers stable current for the RTX 5090 and full component set. The jump is worth it when single-thread speed and sustained multi-core throughput both matter.

Suits creators and engineers needing GPU memory

Professionals running large models, high-resolution timelines or compile farms benefit from 32GB VRAM and rear Thunderbolt 4 connectivity. Buyers who only need 1080p gaming or lighter compute loads should look at configurations with less VRAM and fewer cores. Those requiring more than 64GB RAM can expand to 192GB across four slots.

Questions about this item

What are the case dimensions and motherboard form factor so I can confirm the Z890 TUF ATX board fits?

The Corsair 4000D case measures 490 x 239 x 486 mm and accepts ATX motherboards, so the Z890 TUF board fits without modification.

Which CPU socket and cooler mounting hardware are used for the Core Ultra 7 265K installation?

The processor uses the LGA 1851 socket and the included 240 mm AIO cooler comes with the matching bracket pre-applied; align the pump block before tightening the four thumb-screws in a cross pattern.

How many M.2 slots remain free for future SSD upgrades after the 1 TB Samsung 990 PRO is installed?

The Z890 TUF motherboard provides four M.2 connectors; one is occupied by the factory 1 TB drive, leaving three open slots for additional NVMe storage.
