I plugged the 8 pin on the mother board plus it's extras like led lights speakers etc. and the graphics card, hdd, fans and all USB 2 and 3.0 and put rubber covers on almost all the extra connectors does this mound good for that all also the connectors are all weird and have like 3 of the same ones on one wire do in have to use them all or can I just use the first one on each one?
