Desktop gaming system with liquid cooling

This ArsenalPC desktop uses an ASUS TUF GT302 chassis and ships with Windows 11 Home installed. An Intel Core Ultra 9 285K 24-core processor running at 5.7 GHz drives the system alongside an NVIDIA GeForce RTX 5090 graphics card with 32 GB GDDR7 memory. Sixty-four gigabytes of DDR5 RAM, a 4 TB NVMe SSD and a 2 TB SATA III hard drive complete the specification. The 240 mm liquid cooler and 1200 W power supply support sustained high loads.

Check motherboard socket

The processor fits an LGA 1851 socket and the graphics card requires a PCI Express x16 slot. Verify that your existing motherboard uses LGA 1851 if you plan to reuse it, and confirm the power supply includes the necessary connectors for the RTX 5090. Four DDR5 memory slots are populated, leaving no free slots for additional modules. The 2 TB hard drive uses a standard SATA III interface and the 4 TB NVMe drive occupies one M.2 slot.

ASUS TUF GT302 chassis with 240 mm liquid cooler

The GT302 case houses a 240 mm all-in-one liquid cooler mounted to the CPU, reducing noise under heavy workloads. A 1200 W power supply provides headroom for the 5090 and other components. Front-panel USB and audio ports, integrated Wi-Fi and RGB lighting are included. Component brands may vary from the images shown. The system arrives assembled, tested and ready to use.

Questions about this item

What comes in the box with the ArsenalPC ASUS TUF GT302 and do I need to buy a monitor, keyboard or mouse separately?
