Power over all
The overall performance of both voltage outputs is excellent, there is nothing to criticize. Considering the low street price, the NZXT C1200 is really worth a recommendation, because it doesn’t have to hide behind significantly more expensive power supplies:
Summary and conclusion
The NZXT C1200 Gold is a high-performance power supply that meets the latest ATX v3.0 specifications. Thanks to its 600W 12VHPWR connection, it supports the most powerful graphics cards from NVIDIA to date without any problems and will also be compatible with the upcoming GPUs. The platform achieves good efficiencies, especially at low load, and is compact enough for a 150mm case. The problem is that the smaller the board, the smaller the distance between the components, so the airflow cannot be better optimized. Combine this with the increased capacity of the platform and the lack of suitable heat sinks on the secondary side, and there is only one way to manage the heat inside: increasing the fan speed. The C1200 is therefore not one of the quietest 1200 watt devices, its average noise development is over 35 dBA and therefore in the good mid-range.
At a load of up to 600 W and normal operating temperatures, the noise development is minimal, and only at an output of over 880 W does the noise development of the fan exceed 30 dBA. As long as you don’t put a heavy load on this power supply, you won’t be bothered by the noise. It is good that there is a fan speed profile for several operating and load modes. Under heavy load, other PC parts, such as the CPU and GPU coolers, will most likely make more noise than the power supply, unless you have cooled the PC with a special, ultra-quiet water cooling system.
| Full performance at 47°C ATX v3.0 and PCie 5.0 ready 12VHPWR connection (600W) High build quality Top overall performance Efficient High PF values Quiet operation at light and medium loads Correctly set protective functions Good ripple suppression Long bridging time Low inrush currents at 115 V Low power loss at 115 V ALPM support Fully modular Appropriate distance (150 mm) between peripheral connections FDB fan 10 year warranty |
Increased noise development under harsh conditions Increased vampire performance at 230V The transient response of the 3.3 V rail must be improved |
Many thanks to Aris, whose data I will be happy to use in the future if readers continue to request such power supply tests.
