PSU Question

I'm doing a build for my client, and he brought me a psu that he bought. It's an OCZ 500W PSU (OCZ500SXS), and I'm having a little bit of doubt about the 4-pin motherboard CPU connector. Im going to be building the rig in a Fractal Design Define R4, and I don't think the CPU connector will reach. Can anyone help me with this? Can it reach? Or will I have to order an extension for the cable?
