Where are you from?
Is this for a gaming pc or workstation build or just a regular desktop?
Edit: Well, nevermind.
If you're from the U.S and use newegg here you go: http://www.newegg.com/Product/Product.aspx?Item=N82E16817371029
I don't care if you run your PC from a cardboard box or your friends old PC case until you upgrade but I'm not going to let you buy a bad component for your build, especially a part that can destroy your expensive components like the graphics card or cpu.
