NZXT C1000 ATX 3.1 PSU (White) Review

We like to see Hong Hua Fluid Dynamic Bearing (FDB) fans in power supplies. FDB fans are great for power supplies as they combine great performance against reasonable costs. This is the first white one I think I have seen! This fan is a HA13525H12SF-Z rated at 2,300rpm, 0.5A 12 VDC. This series of fans is used quite often in higher quality units we test.

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 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, but the 1000W adopts 105c KMR Nippon Chemi Con caps. The two primary caps are 420V 560uF for a total of 1120uF. Both Nichicon and Nippon Chemi Con are very high quality (as well as Rubycon, which also may be used).
