NZXT C1200 Gold ATX 3.1 1200w Fully Modular Power Supply Review

A Closer Look – Interior

The cooling fan is a Hong Hua, which is pretty common on modern PSUs and is a brand that is well known to be excellent quality and very reliable. The PSU you’re using right now likely has a Hong Hua fan, as seemingly every brand uses them these days.

NZXT looks to be built around one of the most recent CTT designs, using a semi-digital platform for the 1200W version, and premium-quality components throughout. Of course, that’s not surprising given NZXT is a quality brand and you tend not to get to 1200W easily with cheaper components.

It features a of Rubycon main bulk capacitor, operating at 420v and 1150uF, rated to operate at up to 105c, and that should easily help make up the 1200W main voltage, if not a fair bit more actually, as it’s one of the largest single bulk capacitors I’ve seen in a PSU.

The design is a half-bridge topology, with an LLC resonant converter, again part of the semi-digital design which will help with reducing any heat generation and with improving efficiency.

There are the usual DC-to-DC converters for the 3.3v and 5v rails, but overall, it’s a pretty straightforward design here, with all the components neatly laid out, good airflow throughout, and clean soldering on all the major components.

There are a few small heatsinks, but they appear to be of good quality, and again, there’s plenty of ventilation here so I doubt heat will ever be an issue; clearly NZXT feel the same, hence the zero RPM fan mode.
