Basicly identical pricing to CX500M and Modxstream Pro 500W. Good stuff this.

the internals pretty much looks the same as this one

I reckon they are the same except for the 80+ certification?

From a quick look since I am from the phone now they look the same.

thanks, I'm currently using one and as far as info goes, it doesn't have any certification cause it's 220v only.

CM thunder-m-620w i think is CWT GPM

The Cooler Master GM's CWT original name i don't know, but a 230V only version name is CWT GPN (Chieftec A-90 series) this write on the A-90 label bottom right corner.
Maybe CWT GPN Full Range? 115V 80+Bronze.
Or the Chieftec A-90 name is CWT GPN 230V only version, Chieftec Gold.

Chieftec A-90 (GDP-550C) label and internal pictures:
