Im deciding to get the B450 Tomahawk which only has an 8 pin eps or b450 gaming pro carbon which has 8 pin and a 4 pin eps and im worried whether an 8 pin only would work and will i be able to use the better VRMs on the carbon with better performance than the ones on the tomahawk without using the 4 pin (trying to OC Ryzen 5 1600 from 3.2 to 3.7-3.9)
