Know before you buy
The 140mm depth is quite compact for an 850W unit, making it compatible with most standard ATX cases. However, we recommend checking your specific case's power supply clearance specifications to ensure there is enough room for the cables.
This certification indicates that the power supply operates at a high level of efficiency, meaning it wastes less energy as heat compared to lower-rated units. While the savings on your monthly bill will be modest, it ensures your system runs cooler and draws less power from the wall under load.
Yes, the unit features a Fluid Dynamic Bearing (FDB) fan, which is designed for long-term reliability and significantly quieter operation than standard sleeve-bearing fans. It is well-suited for environments where low noise levels are a priority.
Absolutely. The unit comes equipped with six PCIe connectors, providing plenty of headroom for modern, power-hungry graphics cards and multi-GPU configurations.
A fully modular design allows you to connect only the cables you actually need for your specific components. This reduces cable clutter inside your case, which improves internal airflow and makes your build look much cleaner.
The SuperNOVA 850 P6 uses 100% Japanese capacitors, which are widely considered the industry standard for durability and stable voltage regulation. EVGA backs this reliability with a 10-year warranty, providing peace of mind for the lifespan of your build.
