Functionality
I'm sorry, but I cannot access external websites or specific files online. Therefore, I am unable to translate the text from the provided URL.
'Modern' power supplies often include their own microprocessors and modified software, among other things. Their design and functionality are somewhat more compact and comprehensive than in the past, which can also lead to a higher price. This is often unjustified, but it's usually not apparent beforehand.
And in these cases, I would generally avoid buying from eBay listings.
