About this product

Cybenetics ETA SILVER The GigaMax3 has an ETA Silver efficiency rating, meaning it has a guaranteed typical efficiency of 85%. Cybenetics LAMBDA Not only the efficiency of the power supplies is evaluated, also the noise generated by it. GigaMax 3 series has Lambda grade for certificated silent PSU. Intel ATX 3.1 guide compatible PCIe 5.1 & 12V-2x6 Ready! ATX 3.1 compatible 100% ready for Intel and AMD PCIe 5.1 Ready Supports a dedicated 16pin PCIe 5.1 connector for the latest graphics cards 80 PLUS Bronze 230V EU Certified 80PLUS Bronze guarantees 85%, 88%, 85% efficiency with 20%, 50% and 100% load rates, significantly reducing overall system power consumption. The higher efficiency of the PSU means that there is less leakage of current, which means less heat, high frequency noises, and fan noise. Semi-modular PSU Semi modular design minimizes resistance and voltage drop on the cables and lowers impedance to further enhance energy efficiency, connecting only the cables your system needs to allow for smooth airflow to cool the system.
