Built for heavy rendering and AI workloads

This desktop combines a 24-core Intel Core Ultra 9 285K processor with 192GB DDR5 memory and an Nvidia GeForce RTX 5090 32GB graphics card. The configuration targets professionals running complex 3D modelling, video editing or machine-learning tasks that demand sustained multi-threaded compute and large GPU memory. Windows 11 Pro is pre-installed on an 8TB NVMe array.

PCIe 4.0 storage ceiling and 2.5GbE network cap

The two Samsung 990 PRO drives operate at PCIe 4.0 x4, limiting sequential reads to 7450 MB/s and writes to 6900 MB/s. Rear I/O includes a USB4 Type-C port, USB 3.2 Gen 2 and Gen 1 ports plus four USB 2.0 ports. Wired networking tops out at 2.5Gbps while wireless uses Wi-Fi 7 2x2 with Bluetooth 5.4.

Replaces a workstation limited to 64GB RAM

Builders moving from a system capped at 64GB memory or a graphics card with less VRAM will see immediate gains in dataset size and frame-buffer capacity. The 1200W 80 PLUS Gold power supply and 360mm liquid cooler support the 5.70 GHz boost clock without thermal throttling. Buyers needing more than 8TB of high-speed storage or dual-GPU scaling should look elsewhere.

Questions about this item

Should I pick the 192GB DDR5 configuration or a lower capacity?

The system ships with 192GB DDR5 across four slots, reaching the motherboard maximum. Choose it if you run large AI models, heavy rendering or multi-VM workloads; a smaller kit would leave slots empty and limit those tasks.

What does the Core Ultra 9 285K 5.70GHz boost mean for daily performance?

The 24-core CPU hits 5.70GHz on thermal headroom, so single-threaded apps and game logic get maximum frequency while the liquid cooler sustains multi-core loads without throttling.

How fast are the dual 4TB Samsung 990 PRO drives over PCIe 4.0x4?

Each drive delivers up to 7450MB/s read and 6900MB/s write, so the RAID-0 array can saturate the 4.0x4 link for large project loads and texture streaming.
