ArsenalPC Strix Helios GX601 Ryzen 9 9900X RTX 5060 Ti 16GB DDR5 1TB NVMe 2TB HDD 750W Liquid Cooled Gaming PC

System overview

The ArsenalPC Strix Helios GX601 is a liquid-cooled gaming desktop built around a 12-core AMD Ryzen 9 9900X processor running at 4.4GHz. It pairs that CPU with an NVIDIA GeForce RTX 5060 Ti graphics card equipped with 8GB of GDDR7 memory and 16GB of DDR5 system RAM. Storage combines a 1TB NVMe SSD with a 2TB SATA III hard drive. The machine ships with Windows 11 Home and includes WiFi and RGB lighting. It is intended for gamers and creators who want a ready-to-play system with high core counts and modern memory.

Thermals and power

A 360mm liquid cooler handles heat from the 12-core processor, allowing the CPU to sustain its 4.4GHz base frequency without relying on aggressive fan curves. The 750W power supply delivers stable current to both the CPU and the RTX 5060 Ti under typical gaming workloads. In normal use the cooling loop keeps component temperatures controlled while the fans run at moderate speeds, resulting in a quiet acoustic profile. Power draw scales with the demands of the game or application rather than spiking unpredictably.

Sustained load behaviour

During extended sessions the 360mm radiator continues to dissipate heat effectively, preventing thermal throttling on the 12-core processor and the RTX 5060 Ti. The liquid loop maintains consistent coolant temperatures so clock speeds remain steady across hours of rendering, streaming or competitive play. The 750W unit provides headroom for prolonged maximum utilisation of both the CPU and GPU. Component brands may vary, but the thermal design is validated for continuous high-performance operation.
