The GIGABYTE UD850GM 850W Power supply features a wide range of high-quality materials and designs. Ultra Durable has high-quality Japanese primary capacitors, an improved thermal solution, a 120mm smart hydraulic bearing (HYB) fan, and six circuit safety designs. It provides users with a high-quality, reliable power source that may be utilized for an extended period. The primary capacitors are made of high-quality Japanese capacitors to ensure efficient performance and long-term durability. In comparison to the standard thermal solution, we increased the heatsink size by 200% or more and optimized the airflow. The heat dissipation performance is improved by more than 10%, extending the component's service life. When the system is idle or under a low load (less than 20% load), the fan speed is automatically regulated and ceases. The hydraulic bearing fan has a longer and more reliable life cycle. The GIGABYTE UD850GM 850W Ultra Durable 80+ Gold Full Modular Power Supply comes with a 05-Year Warranty.
