    My X370 Taichi MB went tits up, and rather than waiting for the RMA process, I decided to just get a new MB and RMA later.

    While looking, I noticed that the X470 was not all that much more $$ than the X370 so I decided that I'd go with the X470 since it would be a bit of an upgrade.

    I'll be using my Ryzen 7 1800x on the board.

    Now, the problem/question.

    In addition to the 8-pin 12v CPU connection, there is also a 4-pin connection.

    The manual clearly states to plug in the 4-pin as well as the 8-pin.

    Now, I looked and I don't have a 4-pin cable, nor is there any provision on my HX1000 PSU for one.

    1st question: Is the 4-pin really necessary for the MB to function, or will I have to find a 8-pin to 4-pin cable before I can use the system?

    kirbyrj Why oh why didn't I take the BLUE pill?

    I don't think it's necessary as long as you aren't pushing for some massive overclock. It should boot and function fine.

    If you really want, I'm sure you could find some kind of molex to 4 pin ATX adapter somewhere.

    I was putting my x470 Taichi together last night and was wondering the same thing. I don't plan on OC'ing this particular box but in the end I plugged them in anyway just in case. Luckily there's nothing else attached to this machine - just a video card (Titan Xp), a M2 NVME SSD and a few case fans.

    Have a split 8 pin? May be unnecessary.
