Man, I'm learning new things everyday... So, lemme get some things straight. I can buy a separate PSU, Order a few of these cables and they would be more efficient then the default power bricks? My plan is to get a laptop to run the Singles I have on order. In your picture on your 1st post, that On/Off switch is for the PSU?  I most definitely will be putting in an order when my singles arrive. The SC's, So it might be a bit.
