Today I went into the local microcenter and purchased an Asrock 980de3 / u3s3, amd fx-8350 and pny gtx650TI. When I went home to install it I get no power when I turn it on. My power supply fan attempts to turn on but fails. I hear no sounds and only get a light from the front of the case. My friend has the same setup with less wattage from the power supply and it works fine. What did I do wrong?
