What this build is good for
This high-performance PC build is centered on an AMD Ryzen 9 9900X3D and an RTX 5070, providing a robust platform for 1440p or 4K gaming and intensive productivity tasks like video editing and AI workflows. The ASRock B850 Steel Legend WiFi motherboard leverages the AM5 platform with PCIe 5.0 support, pairing well with the fast WD SN8100 4TB SSD. The Thermaltake Retro 360 TG case offers distinctive aesthetics and high cooling potential, though its unique internal layout requires careful planning for component clearance, particularly regarding the graphics card and front-mounted radiator configurations. While the Gigabyte UD750GM power supply provides adequate wattage and a native 12V-2x6 connector for the GPU, ensure high-quality cooling is sourced for the CPU to maintain stability under load. Users must manually enable the AMD EXPO memory profile in the BIOS to reach the rated 5600 MT/s performance on the Klevv RAM kit.
- Specific manufacturer and cooling design of the RTX 5070 board partner remain unknown.
- A dedicated CPU cooler is not included in the component list and must be verified for AM5 compatibility.

Useful next steps
Enable AMD EXPO
The Klevv FIT V RAM defaults to lower speeds. Enabling EXPO in the BIOS is required to achieve the full 5600 MT/s performance.
Check GPU Clearance
Verify the length of the specific RTX 5070 board model against the Thermaltake case dimensions to ensure no obstruction with front-mounted cooling.
Manage PSU Cabling
Ensure the 12V-2x6 cable from the Gigabyte UD750GM is routed without sharp bends to maintain safe power delivery to the GPU.
