ArsenalPC ASUS ROG GR701 Intel Core Ultra 9 285K RTX 5090 64GB DDR5 2TB NVMe 2TB HDD 1200W Liquid Cooled

System identity

The ArsenalPC ASUS ROG GR701 is a pre-built gaming desktop centred on an Intel Core Ultra 9 285K processor with 24 cores running at 5.7GHz. It ships with 64GB of DDR5 memory, a GeForce RTX 5090 graphics card carrying 32GB of GDDR7, and a 1200W power supply. A 360mm liquid cooler handles thermals while Windows 11 Home is installed on the 2TB NVMe SSD alongside a 2TB SATA III hard drive.

Upgrade context

This machine replaces an older desktop that struggles with modern 4K gaming or heavy creative workloads because its CPU core count, GPU memory or storage speed fall short. The jump is worth it when you need 24 threads at 5.7GHz, 32GB of GDDR7 video memory and a 2TB NVMe boot drive in a single tested system. Buyers who want more storage bays than the single 2TB HDD provides should look elsewhere.

Installation reality

The PC arrives assembled, liquid-cooled and stress-tested so first boot only requires power, display and peripheral connections. What usually goes wrong is forgetting to seat the GPU power cables firmly after transit vibration or neglecting to enable the NVMe drive as the primary boot device in BIOS. The four DDR5 slots are already populated, so future memory expansion means replacing modules rather than adding them.
