• Intel SSD 6
• Samsung 970 EVO SSD
• Gigabyte GC-WB867D-I - Bluetooth/WiFi
• Vengeance LPX DDR4 2x16 (32GB) 3000Mhz - RAM

To power the CPU? Use the 4+4 pin EPS cable plugged into the 8 pin header. Your PSU doesn't have a separate 4 pin to use in the neighboring 4-pin header.

these are the two cables:

8 Pin CPU female to 2 x 8 Pin PCIe male splitter
and
1 x 8pin to EPS12V 8 pin (4+4) Connector

My set up

That first one you mentioned I'd have to see. It isn't listed in the cable selection for that PSU. Unless you are talking about the PCIe 6+2 pin cables. Don't mix them up. They are wired differently. The pos and neg are reversed. In fact, only the 4+4 pin EPS connector should fit the CPU header.
