I am new to custom builds and have the following system:

  • Corsair Obsidian 750D
    250GB SSD
    120GB SSD
    2TB HDD
    GA-Z87X-UD5H MotherBoard
    Corsair CS550M Modular Powersupply

My question; I have 6 black SATA on my board (0, 1, 2, 3, 4, 5) and 4 grey SATA (6, 7, 8, 9) on my board. I know that the black SATA are controlled by the Z87 chipset, while the others are Marvell.

I have installed one OS (win 7) on my 250GB SSD and another OS on the 120GB SSD. The 2TB is used as a storage drive.

My questions:
1) What SATA port on my board should I be plugging my drives into; does it matter the order? (e.g. Win 7 on 0, Win 8 on 1 and 2TB on 2... or can I mix; Win 7 on 0, Win 8 on 3 etc). Does it matter whether I use Marvell or Z87?
2) For power; I have 2 power cables coming off the PowerSupply; one is feeding both SSDs, one is feeding my HDD; does it matter what part of the chain they are connected to?
3) There is a ATX4P (PCIe Power Connector) on my board; do I HAVE to use this? It seems to run fine without it being connected to my powersupply (and frankly, I kind of need that power for my drives, as the way the case positions the drives, it is difficult to daisy chain them)
