    Default New MotherBoard

    I am planning to upgrade my 10-year-old PC, and am looking at this MB to start with - Asus Prime Z950-A

    From the Motherboard Layout drawing, that, there are 2 ATX headers, 1 x 4 pin and 1 x 8 pin header as in the fig below.

    Further down the page, under ATX power connection (2): the diagram shows, either connect the 8-pin or the 8-pin AND the 4-pin.

    I am confused: Should I use only the 8-pin or the 8-pin + 4-pin header ?? Will the 2nd option give more power to the MB?

    My PSU , Corsair RM750i has got only 1 x (4+4) pin connector. Do I need to buy another PSU? Or, is there any adapter cable available?

    The 8 pin on its own will be fine.
    As it says in the Picture 8 pin OR

    Am I right to say that newer PSUs will have 12-pin connector?

    Nope -- Most PSU's come with a 8 pin, which is nearly always able to split into 2 x4.

    Some will have a 2nd 8 pin plug as well. Generally there's a 8 pin and 2 x PCIe

    So, the 8 (4+4) pin configuration is here to stay for many years to come?!

    And, newer MBs are introducing the 4 + 8 pin headers, suggesting that we will need that in the future?

    The 8 pin is common now. There are a few new boards still only have the 4 Socket, but not many.

    Doing a bit of looking (never seen a Board with the extra Socket) but the general reason is when others have asked the same question
    From experience, it suffices to install the 8 pin connector . The right 4-pin-connector is basically a redundancy that the CPU may draw upon under extreme load most likely only relevant when you do extreme overclocking.

    The 8/4 Pin layout would be for OEM power supplies that were of the LGA775 era that come with a 4 pin cable

    Rebuilding a standby HP that had a LGA775 Board upping to LGA1151 that has a 8 Pin board ,just going to populate 4 slots with the standard power supply cable
