Like the other two supplies we have reviewed in this series, NZXT are using Hong Hua Fluid Dynamic Bearing (FDB) fans. FDB fans are great for power supplies as they combine great performance against reasonable costs. This fan is a HA13525H12SF-Z rated at 2,300rpm, 0.5A 12 VDC –  the same fan as found in the 850W and 1000W models.

There is a small plastic flap on the side of the fan to direct the airflow specifically over the heatsinks and components underneath.

NZXT are using CWT as their OEM of choice for this unit. It is a fairly common place design – a half bridge topology on the primary side with an LLC resonant converter. On the secondary side a synchronous system rectifies the 12V rail via 10x Infineon FETs along with DC-DC converters to generate the minor rails.

The soldering quality is high and the overall design uses high quality components throughout. We saw Nichicon primary capacitors in the 850W unit and the 1000W adopted 105c KMR Nippon Chemi Con caps. The C1200 uses Nippon Chemi Con caps – the primary stage has two 105c Nippon Chemi Con KMZ capacitors rated 450V 680uf for a total of 1360uF.
