Right now I have a IN WIN IP-S450CQ2-0 G (3YR) 450W ATX Power Supply (http://www.newegg.com/Product/Product.aspx?Item=N82E16817374049) and I am planning on buying GIGABYTE GeForce GTX 960 4GB WINDFORCE 2X OC EDITION (http://www.newegg.com/Product/Product.aspx?Item=N82E16814125778#). I was wondering if my psu is compatible and can run it. I am fairly new at this, and I don't know how to check if it is.
