[SOLVED] Full modular PSU i have no clue

[AquaralSS]

So, i just bought a CM MWE 650W Fully Modular (80+ Gold). I never in my life dive deep into that section of PSU and now i have encountered my 1st issue.

Should i connect ATX 10P to the main power of mobo? Or just plug in ATX 18P? i know how other ide and cable works but holy, ATX 18P and ATX 10P just freaks me out to a whole new level.

Spec
i5 8400
MSI B360 Pro VH
16GB Ram
240GB M.2 SSD
1TB HDD
GTX970

I believe the 18P and 10P go together for the 24-pin (20+4-pin) MB connection. It should be a single cable.
