New to power connectors, easy question for you guyz. help!

Motherboard - ASUS M2R32-MVP
CPU - AMD Athlon 64 AM2 6000+
PSU - OCZ GameXtream 700W


Hi, a quick question, the psu power leads have a 20 pin atx with an extra 4 pin cable attached to it that has 24 imprinted on it, I connect the 20 pin to the main power socket on the motherboard which leaves a 4 pin space? Do I attach this other 4 pin cable with 24 imprinted on it alongside the 20 pin on the mainboard?
Also their is another 4 pin socket close to the cpu which has (ATX12V) what is this for and what do I connect to it? I have 2 other 4 pin power cables labled CPU1 and CPU2 from my psu. what are these for?

Any help would be much appreciated

Yes you plug in the 4 pin connector (marked 24 pin) next to the 20 connector.
The 4 pin connector close to the CPU is for CPUs that need an extra 12v connection. (I believe your processor does need it.) Plug in one of those 4 pin connectors marked CPU, doesn't matter which one.

hI thanks for the kind info. my 1st pc I built was a pentium 4 with a gigabyte motherboard. I just had the 20 pin main power connector and their wasnt any need for extra power to the cpu. with this newer board/psu and cpu however I was scratching my head. what happened was I just connected the 20 pin and also a pci-e power connector to my graphics card, what I got was - power up/cpu fan on/graphics card fan on/hard drive light stayed on/black monitor screen/both dvd drives wouldnt open and my dvdrw drives busy light stayed on.  . maybe it all just didny have the power cap'n'. Ill try what you offered. thank you very much

You've just described the symptoms of the classic "forgot to insert a 4 pin power connector". I think most PC builders have tried that one, I know I have.

Hilarious thing is - I sent the item back to the website I purchased it from to get it checked for faults and they are sending me a replacemant as they found a fault in the board  how weird is that?, see when you say the 4 pin power connector (the 1 connected to the 20 pin cable or the cpu 4 pin power connector? sorry I am slow hence my username

It was the extra one near the CPU socket I once forgot to plug in... I even rechecked the connections countless times but somehow completely overlooked that plug. Did a lot of head scratching that day.
The effect is pretty much the same though since they're both extra 12v connections. (They're both for the CPU too.) Modern CPUs need a lot of extra juice.

Yep that's weird alright, pretty lucky though.

Give yer self a big pat on the back from me 

1 final question. If i plug in the 20 pin mainboard connector plus the extra 4 pin connector which is attached to the 20 pin with 24 printed on it alongside the 20 pin connector and also connect 1 of the 4 pin named cpu1 or cpu2 into the 4 pin socket on the motherboard named ATX12V... will I fry anything or is that waht Im suppose to do? 

[Deerpark]

That is what you're supposed to do.

  Got my new MB through today. remembered to plug in all power connections and hey presto lol.
Ran into another problem though, I cant enable crossfire in the CCC software. Keeps telling me I havent connected the crossfire bridge interconnections properly, Ive swapped them round and about in every possible combination to no avail. bothe cards are recognised in the device manager however 

PLEH 

[Deerpark]

You've plugged the crossfire bridge in to the cards right?
It should look something like this:

YUP, except that crossfire bridge connector in that picture looks dead 
I'm using both connectors as the little white guy on my right shoulder says thats what it needs 
However the little red guy thats usually on my left shoulder is poking and prodding about with my graphics cards 

Thanks so much for the help so far

Hmm I think someone else will have to take over... don't got personal experience with crossfire so can't really suggest anything else than checking for a newer BIOS version.

Ok m8 thanks for your support  I will try updating the bios
