I bought a new Geforce 2060 to replace my old 660s which were in SLI format. Both required 6 pin Pic Express power cables while the 2060 n required 8 pin. There are 6 to 8 pin adapters that don't require two, but I felt safer not trying to pull 150 watts through 1 6 pin cable rather than the supposed 75 watts.
