Built for high-end gaming and media work

This desktop pairs a 24-core Intel Core Ultra 9 285K with an Nvidia GeForce RTX 5090 graphics card. It ships with 32GB of DDR5 memory, a 1TB NVMe SSD and a 10TB hard drive. Windows 11 Pro is pre-installed on the system.

Arrives fully assembled and ready to use

No component installation is required because the CPU, GPU, memory and storage are already fitted inside the tower case. The 360mm liquid cooler is pre-mounted and filled. Adding more DDR5 modules later is possible thanks to four total memory slots.

Deciding factor is the RTX 5090 with 32GB VRAM

That graphics card determines whether the machine can handle 4K gaming, heavy rendering or large AI workloads. If your projects need less video memory, a lower-tier GPU would cost considerably less.

Questions about this item

How do I confirm the 360mm liquid cooler is keeping the 24-core Intel Core Ultra 9 285K at safe temperatures after assembly?

Enter the BIOS on first boot and watch the CPU temperature at idle; it should sit well below the 5.70 GHz boost ceiling. Under a sustained load the coolant temperature should rise only gradually, showing the 360mm radiator and 140mm fans are dissipating heat effectively.

Which components come pre-installed and which items such as a monitor or keyboard must be purchased separately?

The tower arrives with the Z890 EAGLE motherboard, 32GB DDR5, 1TB Samsung 990 PRO NVMe, 10TB HDD, RTX 5090 32GB GPU, 1200W 80 PLUS Gold PSU, Wi-Fi 7, Bluetooth5.4 and Windows 11 Pro already installed. A display, keyboard, mouse and speakers are not included.

Should I choose the 32GB DDR5 configuration or plan to fill all four slots up to the 192GB maximum later?

The system ships with 32GB DDR5 in a four-slot board supporting up to 192GB. If your workloads — large media projects, heavy multitasking or AI tasks — regularly exceed 32GB, populate the remaining slots with matching DDR5 modules; otherwise the factory 32GB is sufficient for gaming and general use.
