Built for rendering and AI workloads

This desktop pairs a 24-core Intel Core Ultra 9 285K with an Nvidia GeForce RTX 5090 32GB GPU. Sixty-four gigabytes of DDR5 memory and an 8TB NVMe array feed data to the processor at speed. The configuration targets professionals running heavy modelling, editing or AI learning tasks. Windows 11 Pro ships pre-installed on the tower chassis.

Interface limits shape daily throughput

The Z890 motherboard drives the NVMe SSDs over PCIe 4.0 x4 lanes, capping sequential reads at 7450 MB/s and writes at 6900 MB/s. Network traffic runs through a 2.5Gbps Ethernet port and Wi-Fi 6E on the 2.4, 5 and 6 GHz bands. Rear I/O includes one USB4 Type-C, one USB 3.2 Gen 2 and four USB 3.2 Gen 1 ports alongside four USB 2.0 connectors. Four SATA 6Gb/s ports support RAID 0, 1, 5 and 10 for the 10TB hard drive.

Pre-built so assembly risks are removed

The system arrives fully assembled with a 360mm liquid cooler mounted on the LGA 1851 socket and a 1200W 80 PLUS Gold power supply connected. All four memory slots are populated, leaving no room for extra DDR5 without removing modules. The Corsair 4000D case holds two 3.5-inch and two 2.5-inch internal bays for future storage expansion. Buyers who need more than 192GB total memory or a second graphics card cannot use this platform.

Questions about this item

Should I pick the 64GB DDR5 configuration or upgrade to the 192GB maximum?

The system ships with 64GB DDR5 across four slots; the motherboard supports up to 192GB, so you can add modules later if workloads demand more capacity.

What does the 5.70 GHz boost clock mean for actual rendering and AI tasks?

The Intel Core Ultra 9 285K can reach 5.70 GHz on active cores, accelerating single-threaded preview passes and model inference while the 24 cores handle parallel batches.

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

Each drive delivers up to 7450 MB/s reads and 6900 MB/s writes over PCIe 4.0x4, giving the OS and project volumes sustained high throughput.
