Do I need both cpu power connectors with a single e5 2667 v2?

I just received my supermicro x9dr3-f motherboard, which has two cpu 8pin connectors for power, while the power supply I was going to use only has 1. I'm only going to be using a single e5 2667 v2 with it, do I really need to buy a new psu?

The cpu has a 130W tdp.
