EVGA SuperNova 850 P5 Platinum 850 Watt Fully Modular SMPS

The EVGA SuperNova 850 P5 is an 850-watt fully modular power supply carrying the 80 PLUS Platinum certification, which means it operates at 92% efficiency or higher under typical loads at 115 V AC, and 94% or higher at 220–240 V AC. That level of efficiency keeps waste heat low and helps stabilise system temperatures inside your chassis. The P5 is built around an active clamp circuit combined with a DC-to-DC converter and active power factor correction. This topology delivers tight voltage regulation and low ripple on all output rails — a measurable benefit for overclocked CPUs and multi-GPU configurations. The 3.3 V and 5 V rails are generated through a DC-DC converter stage, which improves stability compared to traditional group-regulated designs. All internal capacitors are sourced from Japanese manufacturers. Japanese-brand electrolytic capacitors are widely specified in premium PSU designs for their long-rated service life and temperature tolerance, contributing to the unit’s 100,000-hour MTBF rating. The 135 mm fan uses a Fluid Dynamic Bearing, a design that reduces friction and produces less acoustic noise over its service life than sleeve-bearing alternatives. EVGA’s ECO Intelligent Thermal Control System allows the fan to remain completely stopped at low-to-medium loads, making the unit effectively silent during light desktop or productivity workloads. Fully modular cabling means only the cables you actually need attach to the PSU, reducing internal cable clutter, improving airflow through the case, and simplifying future upgrades. The SuperNova 850 P5 supports NVIDIA SLI and AMD CrossFire multi-GPU configurations and ships with comprehensive protection circuitry: 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).
