Corsair are using a Hong Hua fan. Model HA1225H12F-Z DC12V, 0.58A specification. This is a fluid dynamic bearing (FDB) hydrodynamic bearing fan which should be relatively quiet based on previous experience in testing. The maximum volume is set to 2,300 rpm with an airflow of around 67.3CFM.

This unit is an active PFC + half bridge LLC resonance and synchronous rectification + DC-DC design. The design implements independent PCBs for the DC-DC modules and synchronous rectification. The level one EMI adopts independent PCB design. This is equipped with a pair of Y capacitors and two X capacitors with a common mode inductor. The primary PCB contents the second level EMI circuit including a common mode inductor and a single X capacitor and a pair of Y capacitors. An MOV and NTC are also present. An independent relay is seen between the primary cap and the PFC circuit.

The primary stage has a single Taiwanese 105c rated Elite Jinshan cap. These caps are pretty good, even if they fall a bit short of the highest grade caps from Japanese brands such as Nippon Chemi Con or Rubycon.

The modular bay is home to a plethora of solid capacitors for output filtering. The unit also has OVP, OCP, SCP, OPP and OTP protections in place.
