Motherboards for single core processors ran off of 20 pins.
Dualcores normally require 24pins plus a separate 4 pin which I believes fuels the Ram.

You will definatelly need a new PSU.

Yo. It will work. You can buy a new one if you want, but it will work.

I used a 20 pin on a rig 1.5 years ago and OCed it to 3.6, it was a e7200. Its still running.

E7200 just came out just a few months ago. Like...7.

Anyways, it should work. I think those extra 4 pins are for power phases on the motherboard.
