Built for rendering, editing and AI workloads

This desktop pairs a 20-core Intel Core Ultra 7 265K processor with 192GB of DDR5 memory and an Nvidia GeForce RTX 5090 32GB graphics card. It ships with Windows 11 Pro and a 1TB Samsung 990 PRO NVMe drive, making it ready for professional creative and compute tasks.

Check power, space and connectivity first

The system draws power from a 1000W 80 PLUS Gold supply and fits in a Corsair 4000D chassis measuring 490 x 239 x 486 mm. Verify that your workspace accommodates the case dimensions and that your display supports the GPU outputs. The motherboard provides Thunderbolt 4, USB 20Gbps and 10Gbps ports, Intel 2.5Gb Ethernet, Wi-Fi 7 and Bluetooth 5.4 for peripherals and networking.

Suits creators who need high core counts

Buyers who want more storage than a single 1TB drive, or who require multiple GPU slots for multi-card scaling, should look at a different configuration. The four memory slots are fully populated at 192GB, so further RAM expansion is not possible without replacing modules.

Questions about this item

Does the 192 GB DDR5 fill all four memory slots or do I need to buy extra modules?

The system ships with the full 192 GB DDR5 installed across the four slots, so no additional memory purchase is required.

Should I choose the 1 TB Samsung 990 PRO or add a second drive for more capacity?

The 1 TB Samsung 990 PRO PCIe 4.0 x4 is the only storage included; the case provides two 3.5 inch and two 2.5 inch bays plus three spare M.2 connectors for expansion.

What does the 32 GB RTX 5090 actually deliver when the PC is running a real workload?

The RTX 5090 32 GB GPU is paired with a 20-core Intel Core Ultra 7 265K up to 5.50 GHz, 192 GB DDR5, and a 1000 W 80 PLUS Gold PSU to sustain high frame-rates and compute throughput in gaming, rendering and AI tasks.
