ArsenalPC ROG Strix Helios GX601 Ryzen 9 9950X3D RTX 5090 64GB DDR5 4TB NVMe 2TB HDD Liquid Cooled Gaming PC

System identity

This ArsenalPC desktop pairs a 16-core AMD Ryzen 9 9950X3D processor running at 4.3GHz with an NVIDIA GeForce RTX 5090 graphics card carrying 32GB of GDDR7 memory. It targets enthusiasts who want a pre-assembled, liquid-cooled machine for 4K gaming and heavy content creation. The 64GB DDR5 kit and 4TB NVMe SSD plus 2TB SATA III HDD provide a wide platform for large projects. Windows 11 Home is installed and the system ships tested.

Storage and expansion limits

The 4TB NVMe drive uses a PCIe interface while the 2TB hard drive connects through SATA III, so the board must expose at least one M.2 slot and one SATA port for this configuration. All four DDR5 slots are populated with the 64GB kit, leaving no free sockets for memory upgrades without removing modules. The RTX 5090 occupies the primary PCI Express x16 slot, which restricts the addition of a second full-size graphics card or other x16 devices.

Cooling and power envelope

A 360mm liquid cooler handles the CPU thermal load, and the 1200W power supply feeds the complete build including the RTX 5090. Buyers who need a smaller chassis or a lower-wattage PSU for a compact case will not be able to reuse this cooling and power combination. The fixed 1200W unit and 360mm radiator define the minimum case clearance and power budget for this system.
