According to Newegg you have one 6 pin plug, and one 6+2 pin plug. The +2 means you can remove it and use it in a normal 6 pin slot.
I would return the PSU however. Its junk, plain and simple. A 730W PSU with only 2 plugs? A little red voltage select switch? There is no information at all about how much power the 12V rails can provide as well. Not to mention that Raidmax is known for making junk. Return it, and buy something better. This is about the same price, but much better in quality.http://www.newegg.com/Product/Product.aspx?Item=N82E16817371030
