2X2 or 2X4 cpu power?

[Modred189]

Alrighty folks, I have a Q6700 OC'd to 3.12ghz.
My motherboard is a P5B Deluxe wifi/AP (amazing, love it), [P965 chipset for reference].

The mobo has a 2X4 cpu power connector , and right now, and for more than a year, I have had only the 2X2 plugged in. Never had an issue. Should I plug the second half of that connector in, or should I leave well enough alone?

I'd plug it in, its obviously not needed, but if you have the plug, give it the juice

Either way will work fine, but you may as well plug in the other part. It certainly won't harm anything.
