After almost completing my install. I ran out of connections. I know you can’t use SATA so I need more molex connectors. Is it ok to run these dual connectors? https://www.amazon.com/dp/B00XB7PWB6?tag=tablog-20

You can use it as riser power connector (riser with 6pin PCI-e power). But you MUST NOT use it as GPU additional power connector

Bitcoin mining is now a specialized and very risky industry, just like gold mining. Amateur miners are unlikely to make much money, and may even lose money. Bitcoin is much more than just mining, though!

Can’t I use the 6+2 pins as both 6 and 6+2 pin connectors?  That would leave me 1 short. I could return one of the recently purchased cards to get one with a single connector for connection and that would then get me under what I needed.  I was under the assumption I could use 6+2 connectors as just 6 pins.

Yes, you can use a 6+2 connector as 6 or as 8 pin connector. The specs say it has 10 connectors in total but you need 11. I just checked the picture on the evga website, apparently the PSU comes with 4 cables that have 2x6+2 and 2 cables that have 1x6+2...maybe you can just buy an additional 2x6+2 cables from evga...or you have one laying around already....

Yeah I have a few spares off my old supply that I am replacing that would work. I think this is the best safest long term option. Then swapping out a card for one that takes less connectors.

All the people that I heard say that using any adapters is undesirable. I also try not to use this.

To be safe I think I’ll just upgrade to http://www.microcenter.com/product/458748/GQ_1000_Watt_80_Plus_Gold_ATX_Power_Supply

1000 watts gold rated and 10 connectors. Won’t have to worry about any molex or SATA to run 4 cards and won’t have to worry about coming close to max power on my 850.  I’ll just sell my 850 to recoup some of the cost and have the piece of mind that I’m safe when I’m not at home.
Or keep your original psu for your motherboard and risers and run your gpus off a good server psu from  parallelminer.com that's what I did just a suggestion

just make sure that the (6+2) + 6pin cable from old power supply is compatible with your  new gq unit.
