The use of multiple cables is more of a safety thing as no one cable is working too hard. That’s also why they didn’t just use 1 cable with 4 Molex if i had to put money on it.
And people often forget the drive end of the plug is only supplying one drive and well within its limits, but the PSU side is dealing with ALL the load of every other plug and splitter fed device
This person didn’t take that into consideration like 45 Drives did. Its also why i advise against all these splitters people use and why I prefer backplanes.
