Built for AI workloads and 4K gaming

This desktop pairs an eight-core AMD Ryzen 7 9800X3D processor with 192GB of DDR5 memory and an Nvidia GeForce RTX 5090 graphics card. Two 4TB Samsung 990 PRO SSDs provide 8TB of NVMe storage for large datasets and game libraries. Windows 11 Pro is pre-installed on the tower system.

Assembly completed and stress-tested

The unit ships fully built with a 240mm liquid CPU cooler and a 1200W 80 PLUS Gold power supply already installed. The Antec P20 mid-tower case includes front dust filters and three 120mm intake fans for airflow. No further component installation is required; connect peripherals and power to begin.

192GB DDR5 maximum capacity reached

Four memory slots are populated to the motherboard limit of 192GB, leaving no room for future RAM upgrades. Buyers who anticipate needing more than 192GB of system memory should consider a platform with higher DIMM capacity. The 8TB NVMe array uses both M.2 slots on the PRIME X870-P board.
