How does Technic3D test PSU?

These articles are written in German so I don't think I can fully understand them. Could German readers kindly explain the test methodology of this site?
Their review list is interesting.

Also I found these two Topower. Compare them to a CWT PUFP
Maybe there's some relationship between Topower and CWT?

I know it's not the same, but it's better then nothing.
Altough I fully understand the test, I'm afraid I can not tell you what you are looking for.

The two designs do look like each other. However, I am not aware of any previous Topower/CWT connection other than engineers float between companies quite extensively. Those are both very cheap group regulated designs so they aren't going to be terribly complex for one to rip off of the other if they are not sharing things willingly.

The two designs have exactly the same component position (including every component in EMI filtering stage and standby source) and they choose the very same supervisor chip. There are a few differences, like the markings of transformers, primary/secondary capacitor choice, number of windings on output chokes, number of secondary SBDs, etc. The CWT PUFP I showed is an 270W unit while two Topowers are 350W/400W.

Why they share the same PCB design is beyond me but I'm pretty sure that's the same PCB.
