ArsenalPC ASUS TUF GT302 Ryzen 9 9900X RTX 5090 64GB DDR5 4TB NVMe 2TB HDD Liquid Cooled gaming PC

System overview

The ArsenalPC ASUS TUF GT302 is a new gaming desktop built around a Ryzen 9 9900X 12-core processor running at 4.4GHz and a GeForce RTX 5090 with 32GB GDDR7 memory. It targets enthusiasts who need high frame rates at 4K resolution and creators who rely on GPU compute for rendering or AI workloads. The 64GB DDR5 capacity and 4TB NVMe SSD plus 2TB HDD give ample space for large project files and game libraries. Buyers who want a compact mini-ITX chassis or a system without liquid cooling should look elsewhere.

Installation notes

The PC ships fully assembled, tested and ready to play with Windows 11 Home pre-installed, so first boot only requires connecting power, display and peripherals. A 240mm liquid cooler is already mounted on the CPU, removing the need to handle thermal paste or bracket alignment. The 1200W power supply provides headroom for the RTX 5090 and future upgrades, but builders who plan to add multiple high-power expansion cards should verify the remaining PCIe power connectors themselves. Components brands may vary between units.

Sustained load behaviour

Under continuous heavy workloads the 240mm liquid cooler keeps the 12-core CPU at stable frequencies without the thermal throttling seen on smaller air coolers. The RTX 5090 32GB GDDR7 maintains consistent throughput for extended rendering or compute sessions thanks to the robust 1200W power delivery. The 4TB NVMe SSD sustains high sequential speeds for long transfers, while the 2TB SATA III HDD handles bulk storage without impacting the primary drive. The system is VR ready and designed for prolonged gaming sessions.
