hello, my apologies, it's the P6, I bought it on sale at an excellent price for a second unit, indeed the adapter would be the one for the seasonic, but I'm worried that they may be electrically incompatible in the connection pins of the power supply.I don't get one thing; if you already have Seasonic Focus 1000W PSU (since else-ways, you can't get Seasonic 12VHPWR adapter), then why would you use it with EVGA Supernova G6/P6 1000W PSU? Btw, your topic title says G6, while you list P6 in your post.
