The 24/20 is the main motherboard power connector. It denotes whether the board uses a 24-pin or a 20-pin connector.
The motherboard you chose uses a 24-pin connector (very bottom of the detailed specs). I'm not sure if the PSU in that case will have a 24-pin connector on it's PSU. You should probably replace it anyway. It's pretty weak.
More and more modern cards require a lot of power for them to operate correctly. By giving them their own line straight to the PSU they get better power then having to share off the motherboard with other components.
i thought they used the straight 4 pin molex, but anyway would the best thing to do would be to choose a different case? if i didnt would an atx power supply fit in that mAtx case? i know alot of questions but thanks.
That one is really nice for the price. It's a direct fit for your case as well as having dual 12v rails. Another feature, is that it has a 20+4 pin connector. What this means it has a 20-pin that you can add another four to accomodate newer motherboards.
ok thanks. should be a good machine for the price. im looking to spend >400 dollars so the sempron and onboard graphics are great as a second machine.
thanks for the help ill be sure to come back if i ahve another question
