1070ti

I'm planning on getting a 2nd gpu soon so I can create a dual gpu render system for my work, but my psu only has enough psu connectors for 2 x 8 pin pcie plugs. My 1080 strix is a 2 slot gpu that uses one 8 pin + one 6 pin psu connector. I need a gpu that only needs a single 8 pin psu plug...

I'm looking to buy a full sized GTX1070Ti/GTX1080, I currently have an MSI 1070 Aero ITX but increased my case size to a NZXT H200i and cannot properly cool it so I am looking for a different (and slightly better) card to replace it!
