Manufacturer description

The EVGA SuperNOVA 850 P2 is a fully modular 850W power supply built around 80 PLUS Platinum efficiency, hitting 92% at 115VAC and up to 94% at 220-240VAC under typical loads. That efficiency headroom matters when you are feeding a high-draw GPU and an overclocked CPU from the same rail: less waste heat inside the chassis, and a quieter build overall. EVGA's ECO Mode fan system keeps the 140mm double ball bearing fan completely stopped through low and medium load, so the PSU stays silent during desktop work and only spins up when your rig actually pulls current. Internally, the P2 uses 100%…
