Good afternoon.
There is a motherboard: MSI Z490-A PRO and PSU: Corsair RM750i
The PSU has a free slot for connecting 8 pin wires, and the motherboard has a slot for 4 pin. Please tell me a high-quality wire from the PSU to the motherboard.

Answer 1

There is no standard for modular PSU pinouts. This is what happens when they try to use non-native cables (a person just burned his hardware): https://qna.habr.com/q/796639
Well, if you don’t have an i9 with a TDP 200+ W, then the extra power cable will only for beauty, he really doesn’t need it there. Although no, not only for beauty, it will also impair cooling, because the more cables in the case, the more they interfere with ventilation.
