    If the card supports agp x8 only then it wont work!!!!

    Only cards that suooptt x4/x8 will work!!!!

    You should really replace that inadequate power supply with AT LEAST a 400 watt psu. AGP 8X cards will work in 4X AGP mobo slots. The 8X cards require a bit more power than the older cards did, which is why they have a power connector built into the card.

    If a x8 doesnt support x4 then IT WILL NOT WORK!!!!

    I used to have a x4 mobo and came across this problem!!!

    if the card supports agp4x, can the 230 w psu be the problem ,i read somewhere that minimum 250 w psu is required to run this card

    Yes, absolutely!!!! You could put a terrawatt psu in there (if one exists) and it would not make a blind bit of difference!!!!

    Read the info link i posted, your mobo's agp slot works at 1.5volts whereas an agp x8 card works at 0.8volt!!!! If it did work at all, it would eventually fry the card!!!!
