    PSU motherboard connection.

    My PSU is a silverstone 460W. My new motherboard is an
    AN8. The problem s the PSU motherboard plug doesnt seem to be big enough for the socket on the motherboard (4 pins short)

    Is my PSU now redundant

    You'll be fine just plug the 4pin sqaure connector in and don't remove the protective cap from the other 4 pin holes on the motherboard.
    Also you could try reading your motherboard manual which probably says the same sort of thing.

    there are adapters that convert 20pin ATX to 24pin ATX, I run one, however Im not so sure that the comment about pluging in the AUX 12V is sensible, I still have to plug that into the 8pin aux connector (4pins covered)

    you need a psu, with the 20 + 4 pin connectors. and possibly the P4 and EPS12V connectors too.

    sorry i am thinking the 8pin connector only connecting the 4pin

    if you do mean your psu only has the 20pin thing and your motherboard takes 24 it should still be fine

    Like I said anyway read your motherboard manual

    you can get these connectors from maplin they are only a few pounds but it is strongly recomended that you buy a new psu rather than use one.

    Ermmm, no you dont.
    The AN8 will work fine with just a normal 20pin PSU header and the "intel" 4 pin motherboard one

    I have one next to me

    hi,

    i have a motherboard with a 20 pin socket and have just bought a new psu as the old one fried. The new psu has a 24 pin power plug. i have connected the 24 pin outlet to the 20 pin board and just left the extra 4 pin overhanging the side. (it only fits one way due to the shape of the plug and i checked the wire colours before connecting).

    does anyone know of any reason why this shouldnt be done. saves the cost of a 24-20 pin adpator. the plug is very secure in the slot and the extra outlets are not fouling anything on the board.

    I would imagine there is no problem doing that though I am surprised it actually fits.

    Normally the newer native 24pin PSUs come with the adaptor to 20pin or they have an unclipable 4pins

    going form a 24 to a 20 is fine its the other way round which there is a question mark behind

    I've got a related problem but don't know if it warrants new thread, anyway...
    Just bought a second hand Enermax noisetaker 535w psu, off ebay, which has 24/20 splittable mboard connection but no 12v P4 4 pin connection. Instead it has an 8 pin one.
    Would it be safe to cut the 4 pin connector from an old psu and connect up half the wires?
    If so which psu should I sacrifice - a Qtec 550w dual fan that sounds like you're on a runway, or a Colorsit 400w that came in a case and is virtually slient but weighs 0.0005grms?
    I thought the Colorsit might be useful in an old PIII system since it only draws 50w

    you sure they havent designed a split into it? or you sure you cant just plug it in anywy and have 4 pins off the side? give us some pics if possible

    wouldnt advise it to be honest, if you feel capable enough at soldering and have some good isolating material MAYBE but even so i wouldnt advise it. Try get a connector for it if there is no split.

    The colorsit would be alright for an old PIII system OR you could take the qtec apart and replace the fans with quieter ones
