Box & Bundle
The box has a clean design; on its face, you will find a photo of the PSU with the fan grille and modular panel in sight. The ATX v3.1, Cybenetics, warranty, and 80 Plus badges are in the bottom-left corner. What matters the most for a product package is its protection, and the C1500’s box is fine in this section since foam spacers fully protect the PSU at its internals. There is also a pouch for the vast amount of modular cables, which will be helpful since you most likely won’t use all of them.

The exterior design is simple but nice. The fan grille has many relatively large perforations that don’t restrict airflow. The grille could be even less restrictive to further boost the fan’s performance. On the PSU’s front side are two switches, one for the main power and the other for toggling on/off the fan’s passive operation at light loads.
The modular panel around the back hosts sixteen sockets, including two native 12V-2×6. A warning on this side states that you should not use cables from other power supplies since there is no standard pinout for the PSU modular panels, which is a great shame if you ask me. At some point, all manufacturers and brands should come down to a standardized pinout. This looks impossible for the moment, but hopefully, it will be in the future at some point.
Cables
| Modular Cables | ||||
| Description | Cable Count | Connector Count (Total) | Gauge | In Cable Capacitors |
|---|---|---|---|---|
| ATX connector 20+4 pin (600mm) | 1 | 1 | 16-20AWG | No |
| 4+4 pin EPS12V (700mm) | 1 | 1 | 16AWG | No |
| 8-pin EPS12V (700mm) | 1 | 1 | 16AWG | No |
| 6+2 pin PCIe (650mm) | 6 | 6 | 16AWG | No |
| 12+4 pin PCIe (650mm) (600W) | 2 | 2 | 16-24AWG | No |
| SATA (500mm+145mm+145mm+145mm) | 3 | 12 | 18AWG | No |
| 4-pin Molex (500mm+150mm+150mm+150mm) | 1 | 4 | 18AWG | No |
| AC Power Cord (1370mm) – C19 coupler | 1 | 1 | 14AWG | – |
The ATX cable is long enough, at 600m. The EPS cables are also long, at 700mm, and all PCIe cables are a bit shorter at 650mm. The number of peripheral connectors is high, and the distance between the 4-pin Molex connectors is adequate, at 150mm. The SATA connectors have 145mm between them, which will suffice for most usage scenarios. Lastly, all cables have the standard round shame and are painted black to be stealth inside a chassis with a dark-colored interior. In a PSU costing 370 dollars, someone could expect individually sleeved cables.
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.
