A Look Inside

Before reading this page we strongly suggest to take a look at this article, which will help you understand the internal components of a PSU much better.


Once we removed the casing we immediately recognized the OEM, which is Channel Well Technology (CWT). Tip: you can easily recognize a CWT platform by the green transformers and the green wrapping around the coils.


The first stage of the EMI/transient filtering stages starts at the AC receptacle with one X and two Y capacitors. The second stage on the main PCB has one X, two Y capacitors, two coils and an MOV. The bridge rectifier is a GBU1506. Opposite the bridge rectifier resides a daughter-board that houses the combo PFC/PWM controller, a CM6800. The APFC stage uses two TK20J60U mosfets and the smoothing capacitor is a Samxon (105 °C, 470μF, 400V). As primary switches we find two SPA16N50C3.


In the secondary section, passive design is used for the generation of the DC rails and the three coils indicate independent regulation for each rail. Six STPS3045CT Schottky Barrier Rectifiers (SBRs) handle the +12V rail and each of the minor rails is regulated by one STPS3045CW. The filtering capacitors in the secondary are a mix of Nippon Chemi-Con and Teapo ones and all are rated at 105 °C. We also found a lonely polymer capacitor. Finally, in the secondary heatsink resides the thermistor of the fan RPM control.


The protections IC is a PS229. We couldn't find any info/bibliography about this IC on the internet so we can't say for sure what protections it supports.


Soldering quality is above average but not even close to the best we have seen.


The fan is the same used in the TX750 V2, however this one has LED lighting. It is provided by Yate Loon Electronics and its model is D14BH-12. It's rated for 0.7A, 12V.
