    Guy's I've googled a little and can't find much on it so I decided to ask here :D

    I'm currently looking at 2 very very similar boards the ASUS M4A87TD, EVO and USB3 model's

    Now there is very very little between them as I can see, but one has a 4pin CPU power header whilst the other has an 8pin header. What's the major difference in this? will it affect overclocking and so on?

    The 8 pin is newer technology and in my opinion better.
    I would say better at clocking in general too.

    the difference is more power over more wires....


    i cant see it making a difference with overclocking unless your reaching 4.5ghz with quads or running an i7 overclocked.







    my E7300 dual core hits 4.3Ghz with either the 4 pin or 8 pin, dosnt effect it.

    Well I plan on running an 1055T :D

    As for overclocking it I'll probably be happy 3ghz, so nothing fancy.... and I realised those boards I selected actually have just 4pin CPU power headers but nevermind, it's something I was curious about anyways.

    I believe(correct me if I'm wrong):
    4 Pin is rated for 150w to the CPU.
    8 Pin is rated for 300w to the CPU.

    Though looking at both boards, are you sure one has an 8-pin? I think I'd go with the EVO though, as it has a stronger CPU power design.

    I've not seen a CPU use more than 140w, and those what I have, have been AMD of-course :rolleyes:

    At stock, but once you start to overclock the power can easily go past 150w, especially if you start with a 140w CPU.

    Ahhh I see, So they are only really needed for high end overclocked AMD's ... in a sense :)

    That would be a correct answer...

    You will only need the higher output on the motherboard if you plan to push it hard.
