Power Supplies and (Internal) Power Cables

[fastmachine]

I am very slowly moving forward with a ZFS box running 5 or 6 drives, but am getting a little confused about how advanced power supplies work.

I was looking at getting something like this:
SeaSonic 550W ATX12V 80 PLUS GOLD Certified Modular
It seems to come with 6 SATA power cables, which is fine.

But If I wanted to add a 7th SATA drive is there a type of cable I should buy? Assuming the power supply had enough wattage to support it.

Would I just pick up a cable like this (6-Pin to 5 x SATA). I guess I don't understand if the SeaSonic has a standard or proprietary connector or what.

(I tried looking in the forums and SeaSonic's site, but couldn't find much detail.)

Any help would be great.

If you just needed a few more SATA power connectors, you can get something like this:

Newegg.com - sata power y

Your 550W power supply will have enough power to drive quite a few hard drives, depending on what else you are running.

Thanks.

From another search I found this. It appears that to get the exact OEM SeaSonic cables you have to go through specific suppliers. I will probably just get the Sata Y cable, but incase anyone else is interested.

I think it is easier to make this cable from available at your disposal other SeaSonic's cables and connectors 15-pin power-sata.
I advise you to contact a specialized company.

Don't go for that type of cable, because you are risking it not working with your PSU. Get a 1->4 SATA cable, like the ones made by Asaka or the likes.

I used this one, it works very well:
