Okay so im building a computer with a socket 939 board and an athlon 64 3000 processor. The powersupply I have is an FSP 450watt. So, here's where i'm confused: first off it came with the 20+4 power connector, but they were broken appart. Now, I'm pretty sure I got it on right, but that doesn't cut it for me, how do I now which way those extra four pins are suppose to go. The labeling on the wires does not give them any description. Right now I have the orange and black cords on the outside. Okay, so my next q's is: next to my cpu there is a 4 pin power connection on the motherboard. My manual says it will provide 12V to the CPU power circiut. Does that need to be plugged in and if so is it the 4 cables that are yellow and black. Sorry for the (possibly stupid) q's, especially if I made it sound more confusing than it is. I have never built a system with a newer board. If anyone has an ideas it would really help. Thanks
