The 12V OCP triggering points and the OPP ones are conservatively set. Still, I would like to see a notable difference between the hot and cold OPP triggering pints, and the same goes for the 12V OCP ones. The minor rails also don’t have high OCP triggering points, but again, the triggering points should be much lower under hot conditions. Finally, this is among the few PSUs that have fan failure protection.

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.
