Hello Folks,
If any of the following statements/questions are silly please bear with me.
 
I am for the first time, building a mining rig with following configuration:
 
6x - EVGA - GEFORCE GTX 1070Ti 8GB GDDR (dual 8 pin pcie slots) 
1x - Intel - Core i3-6100 3.7GHz Dual-Core Processor
1x - Biostar - Z270GT9 ATX LGA1151 Motherboard
1x - G.Skill - Flare X 16GB (2 x 8GB) DDR4-2400 Memory
1x - Western Digital - Caviar Blue 1TB 3.5" 7200RPM Internal Hard Drive
1x - EVGA - SuperNOVA G3 1000W 80+ Gold Certified Fully-Modular ATX Power Supply (1 MB connector, 2 CPU connectors, 5 VGA connectors, 4 SATA connectors, 1 PERF connector)
6x - 60cm PCI-E Adapter USB 3.0 1x to 16x GPU Riser 4pin+6pin+SATA
6x - PCI-Express PCIE 8 Pin to Dual 8 (6+2) Pin (power splitter)
1x - Microsoft - Windows 10 Home OEM 64-bit
1x - Fractal Design - Meshify C ATX Mid Tower Case
 
The objective is to build a safest mining rig possible so please let me know if above parts should be replaced with better parts to make the rig safe.
 
I read lots of content on the internet, read forum questions and watched ton of youtube videos, however I still havent figured out how to connect risers and GPUs to PSU. I have following questions:
1) GPU has dual 8 pin pcie slots, does that mean I need to two 8 pin connectors between one GPU and PSU? If yes then it will use up 2 VGA slots on PSU.
2) How do I connect riser to PSU unit? Do I connect one riser (using 6 pin to SATA) to SATA slot on PSU? If yes then it will use up 1 SATA slot on PSU.
3) The PSU has only 4 SATA slots and 5 VGA slots. does that mean I need 3 PSU to connect all 6 GPUs?
4) Is it safe to use power splitter to hook up 1 riser and 1 GPU to 1 splitter? The GPU has dual 8 pin slot so how would splitter work since will have 3 incoming connections (1 from riser and 2 from GPUs)?
 
There are lots of discussions on how not to use SATA connectors for risers as they are not safe. There are lots of discussions on how splitters are not safe. Therefore I am totally confused ... :(
 
Please help, if you have pictures or diagrams to illustrate set up that will be really awesome.

    Thank you Chris
     
    I had reviewed that post ealier. I need more information on how to use dual 8 pin slot for GPU (the post referenced had single 8 pin slot).
     
    Also another question I need some information on is how many PSUs I need for set of 6 (GPUS+risers), 1 Motherboard, 1 CPU? This is considering GPU and riser cables are directly connected to PSU unit. Is is recommended to have multiple PSU for same rig of (6 GPU+risers, motherboard and CPU)?
     
    Thank you in advance.

    Because you got dual 8pin cards the only way to make it work is with cable mods dual 6+2pin cables. Dual 8pin power is rated up to 375W, which is double what a 1070ti is capable of, stupid overkill design.

    As for power requirements, sum up the TDP of all the parts and divide by two or three and multiply that by 1.2 to get the safe wattage of your 2 or 3 power supplies.

    And as I said in the other thread your cpu, board, and risers should all be powered by the same power supply.
