EVGA SuperNOVA 850 P2 80+ Platinum 850W Fully Modular Power Supply
The EVGA SuperNOVA 850 P2 is an 80 PLUS Platinum certified fully modular power supply delivering 850W of clean, efficient power. With 92% efficiency at 115VAC and 94% at 220-240VAC, this unit reduces energy waste and heat output. The ECO Control Fan system provides zero fan noise during low to medium load operations, while 100% Japanese capacitors ensure long-term reliability backed by a 10-year warranty.
EVGA SuperNOVA 850 P2 Platinum Efficiency and Performance
Built on EVGA award-winning P2 platform, the SuperNOVA 850 P2 features a single +12V rail delivering 70.8A (849.6W) for maximum power output and rail stability. The 80 PLUS Platinum certification guarantees up to 94% efficiency under typical loads, reducing electricity costs and heat generation. Heavy-duty protections including OVP, UVP, OCP, OPP, and SCP safeguard your components from power anomalies.
EVGA SuperNOVA 850 P2 Fully Modular Design and Cooling
The fully modular design eliminates unnecessary cables, improving airflow and reducing clutter in your case. The 140mm double ball bearing fan with ECO Mode provides intelligent cooling — the fan stops completely during low to medium loads for silent operation, then spins up automatically under heavy loads. This balance of silence and cooling makes the 850 P2 ideal for both gaming rigs and workstation builds.
