What brand and model motherboard are you working with? I recently put
together a system using a Gigabyte GA-P35-DS3P motherboard, and there was a
plug blocking one half of the 2x4 socket, making it clear that you could use
just one 2x2 12 volt connector if that's all your P/S supported and that was
all that you needed.
I add the part about all that you needed, since it appears that the reason
for using 2 of these 12 volt connectors is to better spread the current draw
out. You are likely to be drawing the most power if you are running a
quad-core processor and raising the voltage in order to overclock it.
Here's an extreme example of what can happen on a motherboard with only the
single 2x2 connector under those circumstances.

(Scroll down to the picture on that page. Since I'm using the same
motherboard that is depicted in the above link, I placed a thermal probe on
its 12 volt socket and ran my dual core processor overclocked, using about
1.4 volts to the CPU, to see how hot it would get. It was about 117 deg.
F., which is warm but I don't think dangerously so. Of course this is just
the temperature on the outside of the socket, and we can assume that it is
considerably warmer inside the socket where the two connectors meet. I also
won't be running my processor with more than about 1.32 volts on a regular
basis.)
The question I can't answer at this point is whether there is a preferred
half of the 2x4 socket to use with just a single 2x2 connector on your
motherboard. Perhaps there is information in your motherboard manual on
that. If you can't find anything in the motherboard's manual, you could
contact the manufacturer's tech support with your question. Some
manufacturer's have user forums that are also a good source of information
on questions such as this, since someone else has probably already raised
the same question.
I hope this is helpful.
