Power supply installation question.

I have this motherboard:Image

and this power supply:Image

In the picture of the connector it looks as though its 1 connector but the 4 pin 12V is actually separate. If I plug the 12V in next to the main connector is that the same as plugging it in to the 12V port at the at the other end of the board which the manual says is for the CPU?

That power supply is made for either a 20 pin or a 24 pin connector on the board. It should have a separate 4 pin tree on the power supply for the CPU . Thats gonna be a separate tree from that connector in the picture. Hope that helps.

P.S. reread it, no that extra 4 pin in the picture is not to plug into the CPU power connector.

I have had to deal with a lot of power supply's before. Could you give me some background on your system. Is it a new system, is it an old system. Is this a new power supply, is this a old power supply. When you try to turn the machine on does the fans attempt to turn then stop, or nothing at all. If this is a replacement power supply does it have a power switch in back etc.

I got it working. :) Apparently even though the connector for the extra 4 pins for the main connector is keyed to prevent it from being plugged in the wrong way, I did. But it is shaped like a square which means 4 possible ways to plug it in if it wasn't keyed. And the key only uses 2 shapes (2 of each shape) which means still 2 ways to plug it in. I guess of the 4 possible was to plug it in, 2(well at least 1) are bad, 1 is harmless, and 1 is the correct way. The key prevents the 2 bad ways.

After some other troubleshooting, I unplugged it and the MB came on. So then I plugged it in the right way and all is fine now.
