Product Description
Asus ROG Strix 1200W Platinum Power Unleashed for Elite Builds

Smart Voltage Delivery for Peak GPU Stability
Experience elite power delivery and cutting-edge thermal management with this next-generation power supply designed for builders who demand top-tier performance and durability. At the core of its innovation lies GaN MOSFET technology, offering up to 30% higher power efficiency compared to traditional silicon-based designs. This not only improves thermal performance with a more compact and organized internal structure but also contributes to quieter, cooler operation under load.
Future-Ready Power for Demanding Builds
What truly sets this unit apart is the patented "GPU-FIRST" voltage sensing system paired with an intelligent voltage stabilizer, boosting voltage accuracy by up to 45% directly to the graphics card. The result is smoother gameplay, reduced power noise, and more consistent performance during graphically intense tasks.

Designed for the Latest GPUs and Standards
Backed by a 10-year warranty, this power supply unit guarantees long-term reliability, making it a premium choice for enthusiasts, creators, and gamers who need advanced features, quiet cooling, and next-level performance in a single, future-ready package.
