Built for AI workloads and 4K creation

This 2026 desktop pairs a 14-core Intel Core Ultra 5 245K with 128GB DDR5 and an Nvidia GeForce RTX 5090 32GB. Liquid cooling keeps the CPU stable during sustained compute or rendering sessions. Windows 11 Pro ships pre-installed on a 4TB Samsung 990 PRO NVMe drive. A secondary 10TB HDD adds bulk storage for project archives.

32GB VRAM on the RTX 5090 decides fit

The graphics card carries 32GB of video memory, the single figure that determines whether large models, 8K timelines or heavy texture sets stay resident on GPU. If your workflow needs more VRAM than 32GB, this system cannot meet it. The Z890 motherboard offers four M.2 slots and four SATA ports for future drive expansion.

240mm AIO and 1000W Gold PSU handle thermals

A 240mm quiet-edition liquid cooler manages the 14-core processor while three 120mm front fans and a 140mm PSU fan move air through the Antec P20 case. The 1000W 80 PLUS Gold supply with Japanese main capacitors delivers stable power to the RTX 5090 and all peripherals. Dust filters on bottom, front and top reduce buildup during long uptime.
