EVGA supernova 850 P5 850W Platinum Power Supply

The EVGA SuperNOVA 850 P5 is built for enthusiasts who demand both performance and efficiency from their power delivery. Earning the 80 PLUS Platinum certification, this PSU operates at 92% efficiency or better under typical loads, meaning less wasted electricity and less heat dumped into your chassis. The fully modular design ensures that only the cables you actually need are inside your case, promoting cleaner builds and better airflow. Under the hood, 100% Japanese capacitors paired with an Active Clamp and DC-DC converter topology keep the 3.3V and 5V rails tightly regulated, which is critical for the stability of modern components.

Noise-conscious builders will appreciate the 135mm Fluid Dynamic Bearing fan, which is inherently quieter and longer-lasting than sleeve-bearing alternatives. When ECO Mode is engaged, the fan does not spin at all under low to moderate loads, delivering truly silent operation during everyday tasks. The included Power ON Self Tester lets you verify functionality before or after installation without connecting to a motherboard. At a compact 150mm in depth, it fits comfortably in most mid-tower and full-tower cases. Backed by EVGA's 10-year limited warranty and their well-regarded customer support, the SuperNOVA 850 P5 is a power supply you can build around with confidence.
