I have bought a new mainboard, an MSI B450 Gaming Pro Carbon, and to my surprise, it features 12 pins for the CPU power connection.
My power supply, a Pure Power 10 BN274 600 Watt, only features 2 x 4 pins connectors. Luckily, it has cable management, yet before I buy an extra 4- or 8-pin cable, I wonder:
Do I actually need to buy an extra cable to get the board up and running? Would the board run fine just with the 8 ports being plugged in? If so, which one should I chose?
The CPU is a Ryzen 2700X.
