Thanks for the posts regarding power. I wanted to err on the side of caution as a beginner. Plus i made the case myself and didnt feel confident with installing power, so this seemed like the best option for now. I read that i should look at having a 'beefy' power supply to have plenty of headroom, hence the 2 row powers. So far i have only 1 row installed and am taking it slowly learning as much as possible about each module. and Wow! what a fantastic journey, modular is amazing.
Made even better by the community that surrounds it.
