THE P7-850W INTERIOR
We don't have much information on the 140mm PWM FDB (fluid dynamic bearing) fan by YiJin Electronics but according to Aerocool it hardly ever spins over 600RPM.
It may not be very easy to spot from this far but the P7-850W was obviously based on a board by OEM manufacturer Andyson.
The two primary capacitors are manufactured by Hitachi and are certified for use up to 105 degrees Celsius.
United Chemi-Con, Nichicon and Rubycon are responsible for the secondary capacitors which in turn are also certified for use up to 105 degrees Celsius (at least the ones we were able to check).
