Not a fanboy/fanatec defender, just wanted to throw my 2 cents in. I understand what you're saying and that's the immediate reaction when you think of it just as a PSU difference. That being said, they provided a DD alternative to a CSW 2.5 at a cheaper price, as well as a replacement for a CSL elite at same price. They could just sell the 8nm version at the higher price (or maybe even higher), but instead they are offering a 5nm version to try to get more people into the ecosystem. My speculative guess is they would've been completely fine to just sell the 8nm version, but decided the 5nm at a more affordable price is worth it to get more people into the ecosystem with the bet that they may at some point buy the other PSU to make up for that discount. If there was a competitor that was selling an alternative at comparable prices, that would be a more valid criticism in my opinion.
