I am aware of all PSU differences.
I also believe,that 99% of PSUs made in the same place,some city in China,probably called PSU-city...thats how they make it,they build a new town to pruduce one specific thing.
I saw a whole city that makes socks only.
So...to the left goes PSU with brand label,to the right goes PSU with some local label for 1/2 or 1/3 of the original price.
They both have gold or platinum certificate,and they are the same.
You're free to choose if you wish to pay double price for a label.
