Processor and graphics core

This desktop centres on an Intel Core Ultra 9 285K processor with 24 cores running up to 5.7GHz and an NVIDIA GeForce RTX 5090 graphics card carrying 32GB of GDDR7 memory. It is built for enthusiasts who want a single system that can run the latest titles at maximum settings while also handling heavy creative workloads such as 3D rendering or video editing.

Memory and storage headroom

The machine ships with 128GB of DDR5 RAM and a dual-drive layout: a 4TB NVMe SSD for the operating system and active projects plus a 2TB HDD for bulk archives. That combination keeps even large texture packs and multi-application workflows in fast memory, while the mechanical drive absorbs long-term media libraries without filling the primary volume.

Power and cooling foundation

A 1200W power supply feeds the complete build and a 360mm liquid cooler keeps the 24-core processor within thermal limits under sustained load. The ROG Strix Helios GX601 case houses the assembly with integrated RGB lighting and 2.5G Ethernet for wired networking. Buyers who need a smaller chassis or a lower-wattage platform should look elsewhere.

Questions about this item

Will the 2.5G Ethernet port work with my older Cat5e cabling?

Yes, the 2.5G Ethernet port is backward compatible with Cat5e cables, though maximum throughput will be limited to 1Gbps on that wiring.

How can I confirm the 360mm liquid cooler is keeping the Core Ultra 9 285K at safe temperatures?

Open the pre-installed ROG software or BIOS to monitor CPU temperature; the 360mm radiator and pump should keep the 24-core processor well within its thermal limits under load.

Does the ROG Strix Helios GX601 case ship with the 4TB NVMe SSD and 2TB HDD already installed, or must I fit them myself?

Both drives come factory-installed and configured; the system arrives tested and ready to play with Windows 11 Home on the NVMe drive.
