Atom Three | RTX 5080 16GB + Ryzen 7 9800X3D | Ready-to-Go Gaming PC | PC36

⚛️ Atom Three

Uncompromising Power, Distilled

Compact doesn’t mean compromise. Atom Three is the pinnacle of performance inside the Cooler Master NR200P Max — a small form factor chassis refined to perfection. Featuring the Ryzen 7 9800X3D and NVIDIA RTX 5080 16GB, this system delivers elite-level gaming and creative performance with whisper-quiet efficiency. Dense, focused and beautifully engineered, it is designed for enthusiasts who demand top-tier power in a footprint that defies expectations.

🧬 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.
