Those people definately have some relation of sorts with Silentpower. I have a 400W psu at home with embossing in the same place, same coating with color (might be a little darker grey) and shine, and the fan-guard looks identical if not the same. Not modular tho. Maybe use the same casing manufs or something.
Seems a decent psu, for close to £100 it would have to be very solid with it`s power quality. Also u can barely hear it
- what a bonus.
