    4pin power connectors?

    You know the 4 pin power connectors you get on new AMD and P4 motherboards - do you have to connect these?

    Will not connecting this have any adverse effect on the computer?

    Thanks

    if you enlarge the pic of the motherboard, you can see the 4pin connector next to the standard atx connector (on the 2nd page there's a better view)

    well thats a lie, but some motherboards seem to need it connected, others dont.. i've got it connected on my is7-e motherboard, but i dont think its compulsory

    On most motherboards your computer will not POST if you havent got the 4pin connector plugged in.

    I read somewhere (Please - don't quote me on it) that this 4 pin connectecter is actually a separate power connecter thats fed to your CPU (instead of using the 12 pin as normal.)

    Hmmm. Why anyway - out of curiosity ?

    well setting up the motherboard linked it first post, as a replacement for 2 faulty pc chips boards i had... it's all a bit academic anyway, as i don't have a psu with that kind of connector at the mo - seems to be working fine so far

    with high-drain devices, it's often needed - it's part of the design - and whether it's impletemented on that model or not does make a difference.
    Both my Tyan Tiger and Thunder series boards require it when the AGP port is in use, but if I use the onboard ATi chip for video, then it's not required. Most of my dual boards need it connected - all the supermicros, a couple of tyans and that's about it. Honestly couldn't tell you for single processor machines.
