Stupid $350 Nov Dec 2012 build

So I just got all the parts I need to make the budget nov and dec 2012 $350 pc. One problem, the motherboard requires a 4 pin connection that the power supply DOESN'T HAVE. What can I do? I assume somebody built this before making it a real video in which case they would have solved this already.

actually, I doubt they did

 

If it has an 8 pin cpu connection just put that in the four pin.  Did you buy the one in the video?

 

I got the exact parts in the video. I only changed cases.

>I assume somebody built this before making it a real video

i seriously doubt it.

 

Can you get some type of adapter?

So I used one of the COMP 8-pins by breaking it apart (didn't even know I could). Thanks so much ragingh4vok for the help.
