Know before you buy
A fully modular design allows you to connect only the cables you actually need to your power supply. This reduces cable clutter inside your case, which improves airflow and makes the initial installation process much cleaner.
EVGA ECO Mode allows the 135mm fan to remain completely off during low-to-medium loads, ensuring silent operation. The fan will only spin up once the power supply reaches a specific temperature threshold, balancing cooling needs with noise reduction.
Yes, the SuperNOVA 850 G6 includes six 6+2 pin PCIe connectors, providing ample power for demanding multi-GPU setups or high-performance graphics cards. Its 850W output and stable +12V rail are designed to handle the power spikes common in modern gaming hardware.
This power supply is equipped with a full suite of safety features, including Over Power, Over Voltage, Under Voltage, Over Current, Short Circuit, and Over Temperature protection. These systems are designed to shut down the unit automatically if an electrical fault occurs, protecting your other hardware from damage.
The SuperNOVA 850 G6 features a compact 140mm depth, which is smaller than many standard ATX power supplies. This smaller footprint makes it easier to install in cases with limited space for cable management or drive cages.
Japanese capacitors are widely considered the industry standard for high-end power supplies due to their superior heat resistance and long-term reliability. Using them ensures the unit maintains stable power delivery and longevity over many years of use.
