Precision Engineering

GaN MOSFET Efficiency
Cutting-edge GaN MOSFETs provide up to 30% higher efficiency while allowing a more compact internal layout. The added space improves airflow and accommodates larger heatsinks for better thermal management.

Intelligent Voltage Stabilizer (IVS)
Activate “GPU-FIRST” voltage sensing via the IVS cable to boost GPU voltage stability by up to 45%, especially during intensive gaming or overclocking. Prefer a CPU-first approach? Just unplug the IVS for conventional power delivery.

High-Performance Copper Pins
Upgraded PCIe® connectors offer superior thermal conductivity, reducing connector temperatures by up to 12.28°C for reliable GPU performance, even during heavy workloads.

ATX 3.1 Ready
Designed for next-gen hardware with tighter voltage and current regulation standards. The included 16-pin PCIe cable supports up to 600W of power for PCIe Gen 5.0 graphics cards.

80 PLUS Platinum Certified
Utilizing premium Japanese capacitors, the ROG Strix 850W Platinum achieves 89% efficiency at full load and 92% at 50% load, reducing heat, minimizing noise, and increasing long-term reliability.

Efficient Cooling

ROG Heatsinks
Oversized heatsinks lower temperatures, extend component lifespan, and support extended 0dB operation for silent performance.

Dual Ball Fan Bearings
With a lifespan of 80,000 hours, dual ball bearings provide durable, efficient, and quiet cooling — outlasting sleeve and even some fluid dynamic bearings.

Designed for Builders

Etched Cables
Flexible, heat-resistant etched cables simplify installation and exceed industry flame and safety standards, making cable management easier and safer.

DIY-Friendly CPU Connector
Featuring a color-coded clip and distinct design, the CPU power cable makes installation faster, easier, and more secure.

Customization Options
Personalize your PSU with included stickers to match your build’s theme and aesthetic.

10-Year Warranty
Built for reliability, backed by ASUS’s comprehensive 10-year warranty for peace of mind.
