So lost on which PSU to get for my unRAID server

[Jake09]

I'm in the process of buying parts for my unRAID build which will run Plex. This is my build.

  

It's my first time building a PC and all is straightforward to me except choosing the PSU. I need help finding the right one that will support at least 8 SATA HDDs for expandability. Such a system doesn't require more than 500w-550w. What confuses me is the SATA power connector having multiple connectors on it. I think this is called daisy chaining and I'm wondering if there will be sufficient amount of power to connect say 4 drives on one strip. Wouldn't I need 1 strip per HDD? I don't think such a power supply exists.   

  

I don't really know how to express my concern in a different way but in a nutshell, I have no clue what I'm doing when selecting the right PSU and I need some help choosing one that will be able to power all my components (1 HDD for now in my build but expanding slowly to 8 or more drives through time).

  

On PcPartPicker I was selecting the filter for the number of SATA connectors I need, at least 8 connectors. Not sure if that's the correct approach.

You can use all the sata ports on one cable. Thats what there there for.

i've run 5 hard drives, 6 SSD's, and an add-in card with sata power (usb card) off a single cable. it's fine.

Great! For non modular PSUs, that's pretty straightforward as I would have to filter by number of SATA connectors I want and that'll be what's included pre attached. For a modular PSU though, what would I be looking for? Any specific requirements on the number of 6 pin SATA connectors on the PSU?

What's your PSU model? I assume you went modular?

i went modular because half the cables in before mentioned system are custom length (being two 8-pins and 24-pin of less than 10cm that's a lot of cabling saved...)
