Corsair are using an NR120L (120mm) fan in this supply. Its a seven blade rifle bearing model with a 50,000 hour life rating. Rated 12V 0.22A. These are not a widely sold fan, but if you look hard you can find them online for around AUS$18 (approx. £9.80). There are no plastic covers on parts of the fan to force direct airflow downwards over specific areas of the unit.

Corsair have partnered up with Great Wall for this unit. It adopts a Resonant LLC topology with DC to DC conversion. It is very impressive to see Corsair using high grade Japanese 105C Rubycon capacitors in the primary stage – two rated 450V 270uF for a total of 520uF output capacity. There are several rows of heatsinks inside the unit to aid with cooling from the fan above. Soldering on the PCB is decent across the board.

The unit has OCP, OPP, OTP, OVP, SCP and UVP protection built into it.
