Hey, I purchased a gtx 1080 aorus , that requires 2 8 pins cables.
I have the seasonic 620w s12ii bronze, which for some reason has one 6 + 2 pin cable pcie and one 6 pin pcie. In the official seasonic web , it says it's supposed to have two 6+2 pin cables, but as I stated it's different. The psu is of good quality and I do not want to upgrade over this , is there something I can do to compensate on the 2 remaining pins?
What are the risks?

Thanks in advance.
