Don't buy that Antec. I have had a few people coming through here and know others with Antec power supplies that have multi 12v rails and have nothing but issues with their rigs.. If you want a good Power Supply don't see how cheap you can go.. Actually a power supply is like your computer insurance policy. The better the power supply is the better your rig is powered or holds up. http://www.newegg.com/Product/Product.aspx?Item=N82E16817139031&Tpk=TX%20650M
and if you want a better quality here is a better one:http://www.newegg.com/Product/Product.aspx?Item=N82E16817139012
and you can get a 10$ mail in rebate for it so itd be 110.
