I have tried so hard to figure this out, but i am concerned that i may ruin the MOBO or PSU by not being somewhat prudent. Checked youtube and posted in other forums and no luck.

Hardware;
BTC 250 PRO Motherboard.
Gigabyte XP 1200M PSU - This is the problem. There are not that many plug connections.
MSI RX 580 OC 8GB (x6)
Molex type Risers (x6)

My concerns;
1. I have 4 x Six PIN connections on my PSU. I will use 3 of them to connect to my 6 molex riser cards. Using 2 molex connections per cable to daisy chain. I will use the cables that came with the PSU. This shouldn't be a problem right ?
2. On the 4th (last) Six PIN connection on my PSU. I will use that to connect to both of the Motherboard PCIE port power via molex 4 pin. Again, 2 molex connections on 1 Six Pin Cable connection. This is what concerns me most.
3. I have 4 x Eight PIN connections on my PSU. I will use 3 of them to connect to my 6 GPU's. Each GPU has only 1x6+2 PIN connection. Using 2 x 6+2 connections per cable to daisy chain. I will use the cables that came with the PSU. This shouldn't be a problem right ?
4. Since i have one last Eight PIN connection. I can use this with an SATA adapter to plug into my SSD. Is this possible too ?

If the above concern No. 2 is not possible, i still have 1 x 4+4 Port open on the PSU, or i can try a different way of connecting the SSD to provide that last Eight PIN Connection.

Sorry for the length, this is my first build, and probably over cautious. Thank you for any help in advance.

Here is a link, that opens I shitty excel diagram with pic's of the above hardware to illustrate it better ( i hope). Zoom in to read the description.

Solution
You have 1100 watts in video cards and only a 1200 watt power supply.
I would return that power supply and buy one bigger with more connectors instead of rigging stuff up.
