💎 Obsidian Three

Unmatched Clarity, Unstoppable Power

At the pinnacle of the Obsidian range, Obsidian Three represents pure performance without compromise. Featuring the Ryzen 7 9800X3D and the NVIDIA RTX 5090 32GB, this build is engineered for enthusiasts who demand the very best in 4K gaming, ray tracing and high-end creative workflows. The Corsair 2500X Woodgrain frame provides the premium aesthetic, while a 360mm ARGB liquid cooler, high-efficiency 1000W PSU and expanded fan setup ensure stability even under the heaviest loads. With every detail considered - including braided cables as standard - Obsidian Three delivers luxury as much as it does power.

🧬 Built to last, designed to evolve

This system is built on AMD's modern AM5 platform, which offers one of the best CPU upgrade paths available today. That means you can start with a great processor now and still have room to move up the stack later, while keeping the same motherboard, case, power supply and most of your core components. GPU, storage and cooling are all easily upgradable so the system can grow with your needs over time.
