EVGA SuperNOVA power supplies are well-known for their extreme efficiency, performance and reliability. In fact, over the last 3 years EVGA SuperNOVA power supplies have won over 70 awards from leading review sites. EVGA's dedication to performance has forged the latest power supply platform: the EVGA SuperNOVA G3 Series. With these new power supplies, EVGA took the best features of the award-winning G2 lineup and made them even better. The SuperNOVA G3's smaller size, improved performance and a new Hydraulic Dynamic Bearing fan give you ultra-quiet performance with an increased lifespan. A reduced size does not mean reduced performance with the EVGA SuperNOVA G3 power supplies. At only 150mm long, this makes these some of the smallest power supplies on the market today, while offering improved performance and features. Better performance, quieter operation and a longer lifespan. Next-generation systems deserve next-generation performance. The EVGA SuperNOVA G3 takes the already efficient G2 series and makes it even better with improved efficiency and lower ripple. These power supplies are over 91% efficient! Use only the cables you need, reducing cable clutter and improving case airflow.
