ArsenalPC ASUS TUF GT301 Ryzen 9 9900X3D RTX 5060 128GB DDR5 2TB NVMe 2TB HDD 240mm Liquid Cooled gaming PC

System overview

The ArsenalPC ASUS TUF GT301 is a pre-built gaming desktop built around an AMD Ryzen 9 9900X3D 12-core processor running at 4.4 GHz and an NVIDIA GeForce RTX 5060 graphics card with 8 GB of GDDR7 memory. It ships with 128 GB of DDR5 RAM across four slots, a 2 TB NVMe SSD plus a 2 TB SATA III hard drive, a 750 W power supply and Windows 11 Home. The 240 mm liquid cooler handles the CPU thermal load in a compact ATX case.

Sustained load behaviour

The 240 mm liquid cooler keeps the 12-core Ryzen 9 9900X3D at stable clocks during extended gaming or rendering sessions, avoiding the throttling that smaller air coolers can allow. The 750 W supply delivers consistent power to the RTX 5060 and all four DDR5 modules without rail sag. With the OS and active titles on the NVMe drive, load times stay low even after hours of continuous use, while the secondary SATA drive absorbs bulk writes without filling the primary volume.

Upgrade context

This system replaces an older desktop that lacks DDR5 memory support, an AM5 socket or a modern PCI Express x16 GPU. The jump is worthwhile when your current platform caps at 64 GB of RAM, uses a previous-generation graphics architecture or relies on a single SATA SSD for both OS and games. Builders who need more than 128 GB of memory, a second graphics card or a larger radiator should look at a different chassis and power budget.
