Corsair are using an NR092P fan, rated 0.22A 12V. This is a good quality FDB (fluid dynamic bearing) fan which we have seen several times in the past. There are no plastic strips on this unit to direct air flow to specific parts – it is just left stock.
This unit is a Great Wall OEM part, like some previous Corsair designs. The PCB is tiny as you can see in the images above and very heavily packed. The build quality looks very good to me and soldering quality on the PCB is excellent.
It is a half bridge topology design and an LLC resonant converter increases the efficiency levels via lossless switching. On the secondary side a synchronous rectification adopts eight FETs to regulate the 12V rail. As usual, the minor rails are generation via a pair of DC-DC converters via a PWM controller.
The primary stage capacitor is a 105c Rated Rubycon rated at 420V 740uF. These are quality Japanese capacitors we value highly, alongside others such as Nippon Chemi Con and Nichicon. The power supply offers OCP, OVP, SCP, OPP and OTP protections.
