So I bought a 1660 from gigabyte because my 1050ti is starting to give me some serious issues. I realized after I bought the 1660 that it needs an 8 pin connector. I have no clue where my bag of psu cables went after I moved, but I rummaged thro my girlfriends psu cable bag and it had what I needed. However when I went to plug that cable into my psu this morning it did not want to plug in. I googled around a bit because I have a corsair psu and the cable was an evga and apparently they aren't standardized. So my questions are, is there any way I can make that evga cable work, will it be ok to run the 1660 on just power from the pci slot until I get a cable tomorrow, and if the evga cable won't work, can I just buy an 8 pin to 8 pin cable on amazon?
