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.

Excellent review , order the C1500 for my system , Amazon UK ,free shipping 40 dollars saved, for a final bill of 285 dollars !!
Great site though, thank you.
For the love of God, please lose the ad at the bottom of the page! It drives me INSANE and no other site I visit has it. Thank you.
Can you send me a screenshot? Also, we need ads to survive!
It’s not the ad itself, but it’s position on the page. The ads either side of your content are not distracting, but the space at the bottom of the page containing the ad that can be hidden, is a constant distraction and a pain in the arse! Anyway, maybe it’s just me.
NZXT C1500 vs Be Quiet! Pro 13 1600W? For future proof (Nvidia RTX 5XXX), less risk with connectors melting and overall performance?
Thanks a lot!
NZXT C1500 ATX v3.1 vs Seasonic PRIME PX-1600 ?
PX-1600
At £150 more for the Seasonic from Scan in the UK!
I just bought the NZXT C1500 based on your excellent review, currently using a Seasonic TX1000. Only upgraded in anticipation of upgrading to a Nvidia 5090. Thanks so much for your content Aris.
MEG Ai1300P vs. C1500
I will buy one of them and really need your opinion on this versus. I’ll be so glad if you reply this one.
Thanks.
C1500
So, I picked C1500 today. Thanks so much again!
Thanks for the thorough review. Maybe I missed it, but I didn’t see any EMI testing. Did you look at that?
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.
