come on, I should inventing a cool name for things that I invented
it's another thing invented by professor "me"
so long story short, I'm already out of molex and sata connector from my PSU,
and I'm gonna need an alternative power source to feed this active shroud which just happen to be the 8p PCIE
(I have an old PSU design which short all the black wire on the 8p PCIE connector to ground )
