Under the Hood
Here are a few pictures showing the layout and components inside the RM850x power supply. The RMx Series was custom designed by Corsair and manufactured by Channel Well Technologies (CWT), one of Corsair’s long standing OEM partners.
The following photo illustrates the main sections within the power supply and their functions.

The Corsair RMx Series PSUs utilizes a modern full-bridge design with LLC resonant converter topology to minimize switching losses and help increase efficiency. Two DC-to-DC converters are used on the secondary to produce the +3.3V and +5V minor rails from the +12V main section.
All of the capacitors used inside the RMx Series are high-quality Japanese made electrolytics rated for 105°C operation. The PSU incorporates two primary capacitors made by Nippon Chemi-Con rated for 470uF, 400V and 105°C. The overall component layout is clean, leaves room for good airflow and the soldering appears very good.
