You can bind them together assuming the single wire can carry the current. The plug that HDPlex uses for the DC(brick) connector binds them together too.i'm just winging this so got a question. how the power into the hdplex is a 6 wire plug should i run each wire to seperate post on the psu or can wire 3live wires to one live post 3 neutral to one neutral post or use all 3 posts ?
