  1. I don't think so, according to the nvidia's site http://www.geforce.com/hardware/desktop-gpus/geforce-gtx-770/specifications , your PSU will not work, "Minimum Recommended System Power: 600w". You can try to use your PSU, but probably you will have problems.
    If you are going to buy a new PSU, use this site http://www.extreme.outervision.com/psucalculatorlite.jsp , you can calculate how many W your new PSU will need, the Corsair TX750 should be enough, it will depends of your CPU
