It's perfectly normal for a power supply to come with 2 CPU 8 pin
Sometimes one of the cables can be split in 2 CPU 4 pin connectors, maybe that's why it says in smaller letters on one cable.
This makes it possible to power a motherboard that has only one 4 pin CPU connector, or motherboards with one 8 pin and one 4 pin connector.
Only ONE 8 pin is needed, if your motherboard has more than one 8 pin. Anything else is optional, and only needed if you have very power hungry processors (think 12 or 16 core processors).
If you don't like the extra cables, then your computer will be perfectly fine with just the 8 pin connector populated.
A single 8 pin connector can give the processor over 300 watts. The 5600x will not consume more than 100-125 watts. Extra power connectors are not needed when the first cable is barely used to half of its capabilities.
