NZXT C1200 ATX v3.1 PSU Review

Average Noise

The average noise output is low.

Fan Noise & Speed Maps @ 28-32 °C – 115V

The fan’s speed is low at up to 600W at 12V, so noise output is below 10 dBA up to that load level. The load on the minor rails generally affects the fan speed, but not significantly. The 30 dBA mark is passed at around 935W at 12V, and the fan’s noise exceeds 35 dBA at 1080W and higher loads at 12V.

The fan speed profile at 230V is slightly more relaxed than at 115V, mainly at moderate to high loads.

  1. Thought I would share my findings.
    Firstly thank you crmaris for the good review based on this I decided to get the NZXT C1200, retiring my Corsair AX1200 (it’s now more than 10 years old). I found that I am using less power now, around 0.5Amps or 115 Watt (@ 230V) less power now, I tested playing the same game for the same period and logging with my Fluke 367FC. I did find that the inrush current is a bit higher at 5.2A, vs the 4.7A my corsair had. But overall super happy.

  2. The difference between the original C1200 and ATX 3.1 version is not just limited to the 12V-2×6 connector. The new version also has one extra PCIe connector, which is good if you have a GPU with three PCIe connectors like the 7900 XTX from AIBs.
