Built for intensive creation

This desktop pairs a 24-core Intel Core Ultra 9 285K processor with 64GB of DDR5 memory and an Nvidia GeForce RTX 5090 graphics card carrying 32GB of video memory. A 1TB Samsung 990 PRO NVMe drive handles the operating system and active project files. The system ships with Windows 11 Pro installed and includes a 360mm liquid cooler mounted on a Gigabyte Z890 EAGLE motherboard.

Suits creators who need local GPU power

Video editors, 3D artists and AI researchers who want a single workstation for rendering, modelling and large-language-model experimentation will benefit from the 24-thread CPU and the 32GB frame buffer. Buyers who need more than 1TB of high-speed scratch space or who require multiple GPU slots for distributed training should look at a different platform. The four memory slots support up to 192GB total, so future expansion is possible without replacing the board.

Extras that change daily use

The 1200W 80 PLUS Gold power supply delivers stable current to the CPU and GPU under sustained load while the 360mm AIO keeps the 285K at working temperatures with low acoustic output. Front-panel I/O includes a USB 3.2 Gen 2x2 Type-C port, two USB 3.0 ports and audio jacks for quick peripheral access. The motherboard adds rear USB4 Type-C, 2.5Gbps Ethernet and Wi-Fi 7 with Bluetooth 5.4, plus four M.2 slots and four SATA ports for additional storage.

Questions about this item

What display outputs does the RTX 5090 32GB provide for my monitors?

The GeForce RTX 5090 32GB includes multiple DisplayPort and HDMI connectors so you can attach up to four screens at once, each capable of 4K or higher refresh rates without adapters.

Can the 2.5Gbps LAN and Wi-Fi 7 share the same network without conflicts?

Yes — the Intel 2.5Gb Ethernet and the 802.11be Wi-Fi 7 radio are separate interfaces on the Z890 EAGLE board, so both can stay active and route traffic independently.

How do I verify the Samsung 990 PRO 1TB is running at its rated PCIe 4.0 speeds after setup?

Open Task Manager or a tool like CrystalDiskMark; sequential reads near 7450 MB/s and writes near 6900 MB/s confirm the drive is operating at full PCIe 4.0x4 throughput.
