Corsair announced RM series silence-oriented power supplies that are capable of running without fan spinning at up to 40% load. They are 80 Plus Gold rated and fully modular.
RM series have six capacity models - 450W, 550W, 650W, 750W, 850W and 1000W. All models are meant to be cooled passively at up to 40% power load. This means 1kW unit runs in Zero RPM fan mode while delivering 400W of power. When the threshold is reached, silent 135 mm Corsair NR135L fan engages.
All RM models have flat fully modular black cables for better cable management, improved airflow and aesthetics.
Corsair RM power supplies are manufactured by Chicony Power Technology/Hipro and CWT, depending on capacities. Units have a MTBF of 100000 hours and are backed by 5 year warranty. Corsair RM PSU series are compatible with Corsair Link software.
