    4pin Or 8pin Power Connections To Motherboard?

    On the PSU there is an 8pin rectangular connection and a 4pin square power connection.

    On the Asus P5K there is an 8pin rectangular power connection in the top-left of the board. However, 4 of the pins are covered by a plastic cap leaving only the 4 pins in the square arrangement (the plastic cap can be removed),

    Am I supposed to remove the plastic cap and insert the 8pin connection?

    Or am I supposed to leave the plastic cap in place and only plug in the square 4pin connection?


    Here is a picture showing both the 4pin and 8pin power connections that I am referring to:

    (I think they are called the P4-12v (4-pin) and EPS12v (8-pin) connections)

    Thanks

    Just a quick question have you read the manual , and I'd think that your supposed to use 4pins if the other 4 are covered.

    The manual says:

    * Make sure to remove the cap on the EATX12V connector before connecting an 8-pin EPS +12V power plug

    * use only either a 4-pin ATX12V or an 8-pin EPS +12V power plug for the EATX12V connector

    * Do not foget to connect the 4-pin/8pin EATX12V power plug; otherwise, the system will not boot


    It doesnt really explain which to use if you have both available

    I think it means you can use either connector (some psu's dont have 8 pin) but you must use one method or the other !!
    Hark the children of the Resolution !!

    Meh, nice and clear manuals dont you love them, personally I'd just stick an 8pin plug in it just to make sure everything gets enough power, its not like somethings going to blow up so I wouldnt worry about it.

    Edit: But if something does catch on fire, blowup, electrocute you I'm not responsible ok.

    Just as Colossus says you can use 4 or 8, depending on what plug your PSU has got. The board'll run fine regardless, but the 8pin can supply a bit more juice. That won't be an issue for a normal setup though.

    Dual Core CPU use 8pin especially if you intend to overclock. The reason it is covered on the mobo is not everyone has a PSU with 8 pins, its supposed to remove any confusion when fitting with 4 pin connectors. Cough.
    Go ahead as the other guys have posted use the 8 pin and it will provide more stability and a bit of piece of mind.

    Thanks guys! Gonna use the 8pin connection as others seem to be using it fine and the extra power can only be good for stability
