What power supply would work best?

[shonenrek]

Hi, I'm planning a budget gaming system build, but I have no idea what power supply I should get. I'm going to get a graphics card later (probably an Nvidia 700 series or something), but for right now, this is what I have picked out: http://pcpartpicker.com/p/9nN24D

So, what power supply do you think I should get? I don't want to go too far above $400 for the system, as I still need room for whatever OS I choose. I also have all the required peripherals, so that's no issue. Thanks in advance for your help!
