What this system is and who it is for

This is a pre-built gaming desktop built around an Intel Core Ultra 9 285K processor with 24 cores at 5.7 GHz. It pairs an NVIDIA GeForce RTX 5090 graphics card with 32 GB of GDDR7 memory, 64 GB of DDR5 system memory, a 4 TB NVMe SSD and a 2 TB hard drive. The 360 mm liquid cooler and 1200 W power supply support sustained high loads. It ships with Windows 11 Home installed and is aimed at enthusiasts who want a ready-to-play 4K machine without assembling parts.

Installing and common issues

The system arrives fully assembled and tested so there is no component installation required. The only physical step is placing the ROG Strix Helios GX601 case and connecting peripherals. Because the chassis is large and the liquid cooler is pre-filled, ensure the intended location can accommodate the case footprint and weight. A frequent oversight is forgetting to connect the 2.5G Ethernet cable or enable Wi-Fi in Windows before the first update, which delays driver installation for the integrated sound and network hardware.

The specification that decides fit

The graphics card uses 32 GB of GDDR7 video memory, which is the single figure that determines whether this build can hold the texture working sets of current 4K titles and professional rendering workloads. If your projects need more video memory than that, this configuration will not meet the requirement. Buyers who need a smaller form factor or a lower power draw should look at other chassis and power-supply combinations.

Questions about this item

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

After setup, open the ROG software suite or BIOS hardware monitor and watch the CPU package temperature while running a sustained workload; it should stay well below the thermal limit with the 360mm loop active.

The box lists a 4TB NVMe SSD and a 2TB HDD — are both drives pre-installed and formatted, or do I need to add a drive or cable?

Both the 4TB NVMe SSD and the 2TB HDD ship installed and formatted with Windows 11 Home on the NVMe; no extra drives, cables or mounting hardware are required.

The system ships with 64GB DDR5 — is that the maximum the ROG Strix Helios GX601 board supports, or can I add more later?

The board uses four 288-pin DDR5 slots; 64GB fills two slots, leaving two free for future expansion up to the chipset maximum.
