GPU power cables

I might get a 3070ti (Gigabyte NVIDIA GeForce RTX 3070 Ti AORUS Master Overclocked Triple-Fan 8GB GDDR6X PCIe 4.0 Graphics Card)  that has a recommended PSU of 850W, but I have a 750W PSU from corsair (CX750F). Would this be a major issue or no? I don't plan to do any overclocking. Also, the gpu has 2x8-pin and 1x6pin connectors, but my psu has 4 total pcie/cpu ports, 2 of which are going to my cpu (5800X). Would using 2 ports with one connector dangling be fine for a 3port gpu? You can visit my profile to see my full spec list if that's of any concern with power consumption. thanks

750W should be fine with a 3070Ti. I can’t imagine why a 3070Ti needs three GPU cables? If so you’d be fine with two and a daisy chain.
