Average Noise
The average noise output is low. Only the extremely efficient Seasonic TX-1600 achieves a better result here.
Fan Noise & Speed Maps @ 28-32 °C – 115V
The fan’s passive operation lasts long, with the PSU registering below 20 dBA noise at up to 1020 loads. The 30 dBA mark is passed at around 1250W, and noise exceeds 35 dBA at 1430W and higher loads. Lastly, the load on the minor rails doesn’t affect the fan speed profile.
Let’s look at the 230V input fan noise and speed maps.

The fan speed profile is almost identical to the one at 115V, with some slight differences in the 800-950W range.

I bought this one to replace my old Corsair RM1000X, but the +12v Rail reports to be 11.904 in BIOS and in Windows it’s between 11.904/11.808; More like 11.808 than 11.904 that is. The PCIe +12v Rails report around v12.060 with v11.883 under load. I wonder whether this is an issue with the power supply or some other component that could be giving me issues. Should I return the PSU?
Do not pay attention to what the mainboard’s sensors say, they are not accurate, at all.
I don’t understand one thing, why this C1500 platform called CTT has the same nomenclature as the platform mounted on XPG Cybercore II 1300 and MSI MEG Ai1000P PCIe5.
They are so different, starting from the double transformer of the 12v, passing through the number of capacitors on the primary, the different dc to dc stage, the different position of many components, the output connectors with only solid state capacitors for c1500 while there are electrolytic ones for the other two. On the other hand the CST platform of the Dark Power Pro 13 1600W is much more similar to the CTT.
the platform has several changes, requested by NZXT as I remember.
Thi is really a great PSU, CWT is always synonymous with trust and quality.
I saw on their site that they produce a 2000w psu with the acronym CTT, atx 3.1 pcie 5.1, 80+TITANIUM, with only one 12V-2×6 connector but there is no review or internal photo to see if the platform is further updated.
Can I say that the C1500 has a superior performance compared to the TF11550?
Yes
Hi,
Just a quick one, those Sunon Maglev fans, do they not have an issue operating vertically- as I read this somewhere.
Thanks
No they are just fine.
