NZXT C1200 Gold 1200W Power Supply - LABS Test Report

Duration: 03:04

The NZXT C1200 Gold ATX 3.1 available at $209 USD delivers generally solid performance, with low voltage ripple, average load regulation, and good handling of power excursions outside of a few short duration failures on the 12V rail. Efficiency is squarely in line with other 80PLUS Gold units, and its strong low load efficiency is a nice advantage for systems that spend most of their time below 200 W. Brownout performance is a clear highlight, sustaining dropouts up to 26 ms at full load, which makes it a good option for users with unstable AC power or those running UPS protected systems.

All of the good results are with the significant caveat that we tested two samples and they both failed while testing the 12V rail OCP. Additionally, the first sample triggered the protections on our AC source during the OCP test, and when plugged in to another power source it emitted sparks before becoming completely unresponsive.

We have informed NZXT of these failures and they have recently finished investigating. They found that operating the unit above the rated load for the relatively long duration of our OCP test caused a buildup of heat and the failure of a MOSFET in the unit. As we say with many other units, our protections testing is quite demanding and a unit that fails these tests may be able to function perfectly well for average use cases.

NZXT encourages all users experiencing product issues to contact NZXT customer support, and we will update this page with additional information if it becomes available.
