ArsenalPC ROG Strix Helios GX601 Ryzen 9 9900X RTX 5090 64GB DDR5 Liquid Cooled Gaming PC

Built for 4K gaming and AI workloads

This ArsenalPC desktop pairs a 12-core Ryzen 9 9900X processor with an NVIDIA RTX 5090 graphics card holding 32GB of GDDR7 memory. The 64GB of DDR5 RAM and a 2TB NVMe SSD alongside a 2TB hard drive provide the throughput and capacity needed for modern titles and creative applications. Windows 11 Home is pre-installed and the system ships tested and ready to play.

Fits a full-tower liquid-cooled chassis

The ROG Strix Helios GX601 case houses a 360mm liquid cooler for the CPU and a 1200W power supply to support the high-end graphics card. Integrated 2.5G Ethernet and a wireless card handle networking without extra adapters. The 288-pin DDR5 memory slots are populated with 64GB, leaving no free DIMM slots for further RAM expansion. Component brands may vary across the build.

Liquid cooling manages the 12-core CPU heat

A 360mm liquid cooler dissipates heat from the Ryzen 9 9900X running at 4.4GHz, while the 1200W power supply delivers stable power to the RTX 5090 and the rest of the system. The closed-loop cooler reduces reliance on high-speed case fans, helping to keep acoustic levels lower during heavy gaming sessions. RGB lighting adds visual customisation inside the chassis.
