New Graphics card issue

[Trix92]

Hey Everyone,

 

I purchased a GPU and Power Supply for my computer but when I installed the graphics card I am met with a No Signal Power Turning off soon screen (All GPU fans are running).

I have a modular Power Supply with 850W (Link To Product https://www.newegg.com/Product/Product.aspx?Item=N82E16817182314) for my GPU (Link to Product https://www.newegg.com/Product/Product.aspx?Item=N82E16814137051 ) for my desktop (Link to Product http://pcsupport.lenovo.com/us/en/products/workstations/thinkstation-e-series-workstations/thinkstation-e20/4222). 

Something I noticed is that the power supply has a 6+2 Pin to 6 Pin  and a 6+2 pin to 7 pin (It's an 8 pin but one of the pins are intentionally missing?)

So here are my questions...

Is this the correct cable for the unit?

Did I just get unlucky and get a faulty GPU?

Is my GPU incompatible with the Desktop?

Any help would be great.

Thanks!
