THE CX850M V2 INTERIOR
The 120mm fan used is manufactured by Yate Loon Electronics and can reach speeds of up to 2800RPM to produce airflow levels of up to 140CFM with up to 48.5dBA of noise (these are the official manufacturer specs, CORSAIR probably used a lower RPM profile).
Judging by the design of the platform this unit is probably manufactured by CWY (Channel Well Technologies).
The primary capacitor is manufactured by the Japanese Rubycon and is certified for up to 105 degrees Celsius.
Secondary capacitors are manufactured by United Chemi-Con and MF electronics (i think, first time I’ve seen these) and are also certified for up to 105 degrees Celsius.
