I'm confused and need help understanding the power connectors going into my optical drive and my hdd. The power connectors are both labeled P4 I believe and they are black and small and somewhat flat. Both have four wires going into the these p4 power connectors. This computer is an acer axc-605-es17. It appears that there is no sata 15 pin connector available available on either drive. Is there a power connector known as P4 or is it just a molex. I looked at a bunch of pictures and these P4 connectors look most like the 4 pin floppy disk drive power connectors. This setup looks genuinely like another piece of proprietary setup. Anybody understanding this I would greatly appreciate. Is there a four pin power connector black besides the white molex 4 pin connector?
