    I am attempting to build a server and using a supermicro SC733T-450 case and a asus NRL-LS533 motherboard. When you look at the board on the asus site it shows a 24 pin power connector which is what I need for the server case.

    However, I ordered the board from Mwave.com and it only has a 20 pin power connector. The manual shows a 20 pin connector also so why do they show 24 pin on the asus site? Did I get an older board or something? The specs on thier site also show a 24 pin connector http://www.mwave.com/mwave/SpecB/BA19507.html

    So I guess I should return the board and get one with a 24 pin connector or could I get an adapter?

    Thanks,
    George

    Being I haven't said anything stupid yet today, at least I don't think I have.
    I haven't done a pentium 4 system yet as I am currently running amd but

    Pentium 4 motherboards and power supplies use the 20 pin power connector in conjuntion with the extra seperate connector. Approved atx pentium 4 power supplies only have the 20 pin connector, not 24

    Could be all wrong but that's what I see

    It has that one, now I wonder where to look to find the adapter locally? There are a lot of online stores that have them

    Turned out that a 24 pin connector on the power supply will plug into a 20 pin connector on the motherboard. The four extra pins just hang off the side.
