This is the popular CSZ platform CWT provides, used in many high-capacity ATX v3.0 PSUs. The design uses analog controllers for all circuits. A half-bridge topology and an LLC resonant converter are on the primary side. The secondary side utilizes a synchronous rectification scheme with ten Infineon FETs generating the 12V rail and two VRMs for the minor rails.
The cooling fan is by Hong Hua and uses a fluid dynamic bearing for lower noise output and increased reliability. Lastly, the build quality is high; the same goes for the soldering quality. At the solder side of the PCB, CWT also enhanced some PCB traces with copper plates, for better conductivity and lower power losses, at high loads.
I won’t stand anymore in this section since I have already described CWT’s CSZ platform in many of my reviews.
Lmao, gotta love the altitude marketing. I want what their marketing team is having 😂
