    Motherboard 8 pin connector

    Hello everyone, just bought an MSI Tomohawk MAX motherboard.

    It has an 8 pin secondary power connector (CPU_PWR1). If you hold the latch at the top then bottom left, bottom right, and the two upper centre connectors are square, the rest are 'house' shaped.


    I have a BeQuiet Purepower L7 530W PSU. That has 2 4 pin connectors marked CPU 1 -P4 and CPU 2 -P8. The CPU 1 -P4 connector looks like it fits the right hand side of the motherboard socket. But the CPU 2 -P8 connector is all houses and no squares.


    Is it supposed to be some kind of universal connector where the 'houses' fit the squares? In the PSU datasheet they're both marked as 12V P4 and shown combining into P8.

    So basically - will I break anything using these PSU connectors on the motherboard?

    Thanks

    Re: Motherboard 8 pin connector

    The motherboard manual should have layout of the socket if you want to compare. It makes sense to me but as you've done I would match them up too.

    They all look like that mate, plug it in, it will be fine.

    You will find one of those blocks will only go one way

    Re: Motherboard 8 pin connector

    Yeah those two may even have a little ridge that kinda holds them together (sort of, it's more of a guide, my fat fingers always find it a bit fiddly)

    There is only one orientation that the clip will then latch onto the motherboard connector (plugging the two in as one unit at the same time)
    Grab that. Get that. Check it out. Bring that here. Grab anything useful. Take anything good.

    Re: Motherboard 8 pin connector

    It's taken a while for an update because the connector was in the very far corner of the mobo so the PSU cable wouldn't reach! Had to buy an extension:

    This has the same mismatched connector layout as my PSU and worked fine. No smoke yet

    Thanks to everyone for your help

    Re: Motherboard 8 pin connector

    Just doing my build atm and the seasonic connectors look the same as your pic but helpfully label them as " CPU" so no ambiguity sfaik that is what they're for.
