System purpose

This ArsenalPC desktop pairs a Ryzen 9 9900X3D processor with an RTX 5090 graphics card in an ASUS TUF GT302 case. The 12-core CPU runs at 4.4 GHz and is supported by a 240mm liquid cooler. It targets gamers and creators who want a pre-built Windows 11 Home system that ships tested and ready to play.

Graphics memory

The RTX 5090 provides 32 GB of GDDR7 video memory, the single specification that determines whether this build suits 4K or multi-monitor workloads. Buyers who need more VRAM for larger datasets or higher resolution textures will find the ceiling fixed at this level.

Storage and memory headroom

A 4 TB NVMe SSD and a 2 TB HDD combine for 6 TB of total capacity, while 128 GB of DDR5 RAM handles large project files and heavy multitasking. The 1200 W power supply and 2.5 G Ethernet port support the installed components, though the single GPU slot means a second card cannot be added.

Questions about this item

How does the 4.4 GHz clock on the Ryzen 9 9900X3D behave under sustained gaming loads?

The 12-core processor runs at a base frequency of 4.4 GHz and uses a 240 mm liquid cooler to maintain high clocks during extended sessions, while the 1200 W supply ensures stable power delivery.

What practical throughput does the 2.5G Ethernet port provide for local file transfers?

The 2.5G Ethernet connection supports up to 2.5 gigabits per second, allowing fast LAN transfers and low-latency online play without needing a separate add-in card.

Will the ASUS TUF GT302 case accommodate the 240 mm liquid cooler and RTX 5090 together?

The GT302 chassis is built for 240 mm radiators and full-length graphics cards, so the factory-installed liquid cooler and the RTX 5090 fit without modification.
