EVGA Supernova 850 P5 80+ Platinum Fully Modular ATX Power Supply ( 850 W )

The EVGA SuperNOVA 850 P5 is an 850-watt ATX power supply built for enthusiast desktop systems that demand clean, efficient, and quiet power delivery. Carrying the 80 PLUS Platinum certification, it achieves efficiency ratings of 92% or higher at 115 VAC and 94% or higher at 220–240 VAC under typical loads, meaning less energy is wasted as heat and your components receive stable, consistent power. The fully modular cable design lets you connect only the cables your build actually needs, reducing cable clutter inside the chassis and improving airflow around critical components. This is especially valuable in compact mid-tower and full-tower builds where cable management directly affects cooling performance. At the heart of the P5's quiet operation is a 135mm Fluid Dynamic Bearing fan. Fluid Dynamic Bearing technology reduces friction compared to conventional sleeve or ball bearing fans, resulting in lower noise levels and an extended operational lifespan. EVGA's ECO Intelligent Thermal Control System takes this further by allowing the fan to remain completely off at low to medium loads, making the PSU effectively silent during light gaming, productivity, and media playback tasks. The unit is built with 100% Japanese capacitors throughout, a component choice that supports long-term reliability under sustained thermal and electrical stress. An Active Clamp plus DC-to-DC converter topology provides tight voltage regulation on the 3.3V and 5V rails, while Active Power Factor Correction ensures a clean power draw from the wall outlet. Six layers of hardware protection — Over Voltage Protection (OVP), Under Voltage Protection (UVP), Over Current Protection (OCP), Over Power Protection (OPP), Short Circuit Protection (SCP), and Over Temperature Protection (OTP) — safeguard your system against a wide range of electrical faults. The P5 supports NVIDIA SLI and AMD CrossFire multi-GPU configurations, backed by six 8-pin (6+2) PCIe connectors. A rated MTBF of 100,000 hours and a 10-year manufacturer warranty reflect confidence in long-term build quality.
