Ultimate Blackout 2026 Gaming PC Build | No RGB | RTX 5090 + 9800X3D + Lian Li O11 Vision

Welcome to the new chapter of PC Elegance and gaming PC building. It’s already 2026, and I decided to revisit the PC build that started everything, the aesthetic that defined this channel from the very beginning. A new blackout gaming PC for you. This is the Anti-RGB masterpiece, a blackout pc build designed to prove that raw power needs no glow. Built inside the iconic Lian Li O11 Vision, the system combines visibility with restraint. At the heart of the build is the most popular AMD Ryzen 7 9800X3D, paired with the monolithic ASUS GeForce RTX 5090 ROG Astral OC. The new ASUS ROG Crosshair X870E Dark Hero motherboard ties everything together with precision and stability, while G.Skill TridentZ5 DDR5 memory keeps the system fast and responsive. Storage is handled by dual Kingston Fury Renegade G5 2TB SSDs, pushing next-generation speeds for both gaming and production workloads. Power comes from the new Lian Li RS1200G 1200W PSU, ensuring clean and reliable delivery under heavy load. Cooling is built around performance-first philosophy. The ARCTIC Liquid Freezer III Pro 360 AIO, combined with ARCTIC P14 Pro Reverse and P12 Pro fans, creates efficient airflow focused on thermal control rather than visual spectacle. Thermal Grizzly Contact Frame and PhaseSheet PTM complete the setup for maximum efficiency and stability. This build is more than just a pc build. It’s a continuation of the idea that started this channel, a blackout gaming pc that proves elegance and performance can coexist without RGB. A new version. A new vision. The same philosophy. If you’re looking for inspiration for your next gaming PC, learning how to build a PC, or searching for the ultimate no RGB PC, this build is made for you. 👉 Don't forget to like, subscribe, and hit the bell. 💥 Want to support my PC builds and help bring more epic content to life?
