  1. Are you inquiring about the CPU Auxiliary power connector? If so, use the 8 pin EPS connector if your motherboard has an 8 pin socket, or the 4 pin ATX connector if your motherboard has a 4 pin socket. Most PSUs expose this as a 4+4 for ease of use.
  2. The ATX 12V (The EPS is for Servers)
  3. i have an 8 pin connection

    In that case you can use either the 8 pin EPS connector or the 4+4 pin ATX/EPS connector. I'm unsure why Seasonic felt it was necessary to include the 8 pin alongside the 4+4, but they are electrically identical. The only difference is that one can be decoupled to fit in motherboards that have only a 4 pin socket.
