ATX 20 pin and 24 pin

I recently bought an Antec SLK2650 BQE Solution series case. It came with an Antec 350 watt SmartPower PSU. I noticed that the ATX main power connector is 24 pins. It has a notch at the 10th row of pins, seeming to indicate it will work with my 20 pin board. According to the manual, it says is backwards compatible with previous ATX power supplies. Is this correct, or do I need to buy a 24 pin to 20 pin connector?

***Update: I have discovered that the 24 pin connector actually splits. Four pins at the end of the connector come off and detach from the rest of the connector. It seems that it will work fine, with my 20 pin board. Am I right on this issue? Also, there is a wire missing inside the 20 pin connector, is this normal?

  1. Is it right that there is a wire missing in the 20 pin connector? I turned it on, and my diagnostic card showed that the 12V, 5V, and 3.3V were correctly wired by lighting up on the card. I don't really feel like opening up my case to find out. LOL.
  2. That is what I figured. There is 20 pins on the motherboard, and on the connector there is 19, and the 20th has nothing. No wire, metal connector, you can see right through it.
  3. yea...who on earth would want a 19 pin connector?
