They look absolutely the same to me. Top is old one, bottom new one.
Mobo is a rog strix z690 a d4, there's no difference as to how they are powered/connected to the mobo and they use the same psu cable (I'm not using any sata power splitter). I tried removing the old hdds and connecting only the new ones, using the same cables too, but nothing changed, they just don't show even in the mobo.

As far as I know they're all legit, and I bought them from the same amazon page, https://www.amazon.co.uk/dp/B07XM9RM95
