Corsair are using a 120mm Hong Hua fan model number HA1225H12F-Z. This is a rifle bearing fan rated 12V 0.58A. You can buy these fans online for around £10. This is not as high a grade unit as the Hong Hua Fluid Dynamic bearing models you will find in their more expensive units. As I said earlier- always going to be certain tradeoffs when you move down a companies product stack.
The OEM for this power supply is HEC. This is a half bridge topology on the primary side with an LLC resonant converter. The secondary side uses a synchronous rectification system for the +12V rail which powers a pair of VRMS to create the minor rails.
The PCB inside is quite small and densely populated with several large heatsinks to aid with cooling – this makes sense with vertical PCB boards mounted to the main one. One of the boards is home to the DC-DC converter to generate the minor rails.
Soldering quality is high throughout and the main PCB exhibits great attention to detail in this regard. I was a little disappointed to see a Taiwanese TEAPO primary capacitor used in this unit, rated 400V 680uF, however my bad experiences with this company happened a long time ago – we would like to hope that their standards have improved in recent years. Regardless – these are not high end units so we have to expect some compromises in the designs and component selection to hit specific price points. On a plus point, this primary cap is rated 105c, not 85c.
This unit ships with OCP, OVP, SCP, OPP and OTP protections.
