Power Supply FAQs
  • The different connectors of a computer power supply:

    • The 4+4-pin, or 8-pin, CPU power connector.

    • Since the ATX12V specification replaced the ATX specification, the CPU has received it's power from a regulated +12V source. This +12V comes from either a 4-pin or 8-pin power connector. Prior to the advent of the "CPU power connector", as it is often called, CPU's voltage was regulated off of the +5V. But it was soon realized that with faster, more power hungry processors, more power could be delivered to the board by using a higher voltage and delivering it through it's own dedicated connector.

      Some motherboards utilize an 8-pin CPU power connector. This connector can provide even more power to the motherboard than the 4-pin. In order to accommodate motherboards that can use either 4-pin or 8-pin CPU power connectors, some power supplies have a 4+4-pin connector. This is essentially an 8-pin power connector that splits in half. All BFG GS and LS Series power supplies utilize 4+4-pin CPU power connectors


      This 4+4-pin power connector can be split for use with a 4-pin CPU
      power socket or combined for use with an 8-pin CPU power socket.


      The EPS12V 2.91 specification has provisions for motherboards that support multiple processors and have multiple CPU power connectors. These motherboards have both 8-pin and 4-pin CPU power connectors. All ES Series power supplies have both a 4-pin and 8-pin power connector.
