Molex and Sata I'm 100% sure of.
PCI-E cable... 2x 8 pins going into one plug to the PSU (12pin).
PSU plug has numbers on them. Assume same orientation on each 8pin plug -
[1][2][3][4]
[5][6][7][8]
```` <- clip lock
them ```` being the clip lock, and looking from the cable side.
Top view
[][][][] <- to PCI-E socket on gfx
[ ____] <- plug casing
Is it clear?
