Look at the MB female plug and compare with the cable, you can deduce the cable pinout from looking at the RM750 PSU in case of corsair cables
The Hale90 fully modular have certain models with a full 12x2 layout that looks as if a normal 24pin extender cable would fit if you modded it male/male. link to the specific model.
I looked at the EVGA PSU female plugs and compared them to the Corsair female plugs.
On the EVGA PSU there are different numbers on each of the 24pin plugs.
I compared the G2 to the RM - Not the NZXT Hale90
The only way I could find is using extender cables or sleeving myself, Bitfenix makes extenders.
But then you would have to hide the non sleeved cables - you would the not need a modular PSU
to change the colour of cables, but it would be messy.
I have the H440 so the PSU is hidden and therefore I will go with the RM750
