This new Corsair RM850x has proven to be a very capable power supply in our testing over the previous week.
Ripple suppression is very tight and falls well within industry rated parameters and load regulation also proves a good selling point across all the rails.
It's quite expensive
Price: around 160 euros · Efficiency rating (115V): Cybenetics Gold (87-89%) · Efficiency rating (230V): Cybenetics Gold (89-91%) · Noise rating: Cybenetics A (20-25 dB[A]) · Warranty: 10 years
The Corsair RMx series has been updated to meet the requirements of the ATX v3.1 standard
For example, if a fan speed of 500-600 rpm is selected at low load, this serves as a start point and increases as the thermal load on the power supply increases.
