High-quality, low-noise capacitors and transformersThe Corsair RM850 is designed with capacitors and transformers carefully selected to eliminate coil whine and other background noise that can be annoying in quiet environments.
Zero RPM Fan ModeThe efficient design of the RM850 means minimal excess heat generation, so the fan doesn't even need to spin under low to medium loads. And when you're pushing it hard, the thermal sensor controls the fan speed to ensure that it gets the cooling it needs without any extra noise.
Corsair NR135L Noise-Reducing FanThe custom-designed fan has an optimized blade profile for low-turbulence airflow and near-silent operation, even at full speed.
