Adamant Custom Ryzen 9 9900X3D 128GB DDR5 8TB NVMe RTX 5070 Ti gaming PC

Built for heavy multitasking

This system pairs a 12-core AMD Ryzen 9 9900X3D processor with 128GB of DDR5 memory and an Nvidia GeForce RTX 5070 Ti graphics card. Two Samsung 990 PRO SSDs provide 8TB of NVMe storage. The tower chassis uses a 240mm liquid cooler and ships with Windows 11 Pro installed. It targets professionals who need strong single-thread speed and large memory capacity for modelling, rendering or AI workloads.

Check your environment

The PC draws power from an 850W 80 PLUS Bronze unit with a 140mm fan. Rear I/O includes two USB4 ports, one USB 10Gbps port, three USB 5Gbps ports and four USB 2.0 ports plus 2.5Gb Ethernet and Wi-Fi 7. Front-panel connectivity offers two USB 3.0 ports, one USB 3.2 Gen 2 Type-C port and audio jacks. The case measures 469mm deep by 220mm wide by 490mm high; verify desk or rack space before ordering. Four memory slots are populated, leaving no free DIMM slots for future expansion.

Thermals and acoustics

A 240mm quiet-edition AIO handles CPU heat while three 120mm front fans feed the GPU and motherboard. The power supply uses a 140mm fan rated for low noise. Dust filters on the bottom, front and top help maintain airflow over time. In typical mixed workloads the liquid loop keeps the 12-core chip near its 4.4GHz base clock without aggressive fan ramps, and the RTX 5070 Ti 16GB card stays within its thermal envelope under sustained compute or gaming loads.
